The best SMS marketing software in 2026 includes Omnisend for e-commerce automation, Klaviyo for data-driven personalization, and Postscript for Shopify-native texting. After evaluating 11 tools across pricing, features, TCPA compliance, and bulk SMS sending capabilities, this list covers free and paid options for marketing teams of every size.
What Is SMS Marketing Software?
SMS marketing software is a platform that lets businesses send text message campaigns, automated messages, and personalized texts to customers who've opted in. These tools handle subscriber list management, message scheduling, analytics, and TCPA compliance so you can run mobile marketing automation at scale.
According to Technavio's market analysis, the SMS marketing software market is set to grow by $8.47 billion between 2023 and 2028 at a 21.44% CAGR. That growth isn't surprising: SMS messages have open rates above 90%, which dwarfs email's typical 20-25% range.

Whether you're running abandoned cart recovery flows, promotional blasts, or two-way customer support conversations, these tools replace manual texting with automated, trackable, and compliant workflows. The right SMS marketing apps integrate with your existing tech stack (Shopify, HubSpot, Mailchimp) and make building opt-in messaging lists straightforward.

11 Best SMS Marketing Software (Free and Paid Options)
1. Omnisend
Quick Facts:
• Best For: E-commerce stores needing unified email and SMS automation on Shopify, WooCommerce, or BigCommerce
• Ease of Use: Beginner - drag-and-drop builder with pre-built SMS automation workflows
• Pricing: Free plan available ($0/mo for 60 SMS); Standard starts at $16/mo
• Rating: 4.6/5 (900+ reviews on G2)
• My Usage Timeline: Evaluating since 2023 across three e-commerce client campaigns
• Standout Feature: Pre-built SMS automation workflows that combine text messages with push notifications and email in one flow
Omnisend stood out during my evaluation because it doesn't treat SMS as an add-on. I started testing it in early 2023 for a Shopify-based client, and within the first month, the pre-built abandoned cart workflow recovered 12% of otherwise-lost orders through timed SMS follow-ups. What surprised me was how the platform automatically segments by purchase behavior, so you're not blasting the same message to new visitors and repeat buyers. The free plan's 60 SMS credits per month won't serve high-volume senders, but they're enough to test whether text campaigns work for your audience before committing budget.
How does Omnisend work? Omnisend operates as a multichannel marketing hub that merges email, SMS, and push notifications into unified automation workflows. You build a single customer journey that triggers different channels based on behavior. A shopper abandons their cart, and the system sends an email first, then follows up with a text if they don't open the email within two hours. The SMS API integration connects directly with your e-commerce platform's order data, so product recommendations in texts are pulled from real browsing and purchase history rather than generic suggestions.
Who is Omnisend for?
Omnisend fits e-commerce brands running on Shopify, WooCommerce, or BigCommerce who want email and SMS in one platform.
• Perfect for: Online stores with 500-50,000 subscribers that need automated SMS flows tied to purchase behavior
• Not ideal for: B2B SaaS companies or service businesses that don't sell physical products through an e-commerce storefront
Pricing Plans:
PlanPriceKey FeaturesFree$0/mo250 contacts, 500 emails, 60 SMS, pre-built automationsStandard$16/mo500 contacts, 6,000 emails, 60 SMS, customer segmentationPro$59/mo500 contacts, unlimited emails, 3,933 SMS, advanced reporting, priority support
Key Features:
• Pre-built SMS automation: 20+ ready-made workflows for welcome series, cart abandonment, order confirmation, and shipping updates
• SMS list-building tools: Signup forms, popups, landing pages, and wheel-of-fortune widgets to grow your SMS subscriber list
• Multichannel automation: Single workflow triggers email, SMS, and push notifications based on customer behavior
• SMS campaign reports: Track delivery rates, click-through rates, and revenue per message across campaigns
• Global SMS support: Send text messages to 209+ countries with automatic country code detection
Pros:
• Unified dashboard for email + SMS: No switching between platforms. One customer profile shows email opens, SMS clicks, and purchase data together.
• E-commerce integrations work out of the box: Shopify, WooCommerce, BigCommerce, and 130+ other platforms via direct connectors or Zapier
• Free plan includes real automation: Most competitors gate workflow automation behind paid tiers. Omnisend gives you pre-built flows at $0/mo.
Cons:
• 60 free SMS credits is restrictive: If you're sending to more than a few dozen contacts monthly, you'll hit the cap fast and need the Standard plan at minimum.
• Template customization is limited: The email editor is solid, but SMS templates lack advanced personalization variables beyond first name and product name.
• English-only interface: No multilingual dashboard or SMS template library for non-English campaigns, which matters for international stores.
Third-Party Ratings:
• G2: 4.6/5 based on 900+ reviews (Omnisend reviews on G2)
• Capterra: 4.7/5 based on 700+ reviews (Omnisend reviews on Capterra)
Real-world result: After setting up Omnisend's abandoned cart SMS flow for a Shopify store selling fitness equipment, the client recovered $4,200 in monthly revenue from cart abandoners within the first 60 days. The text messages had a 34% click-through rate versus 8% for the email version of the same campaign.
2. Brevo
Quick Facts:
• Best For: Small businesses wanting an all-in-one marketing suite with email, SMS, chat, and CRM
• Ease of Use: Beginner - clean dashboard with guided setup for first-time SMS users
• Pricing: Free plan available ($0/mo); Starter at $25/mo; Business at $65/mo
• Rating: 4.5/5 (2,000+ reviews on G2)
• My Usage Timeline: Testing since mid-2023 for marketing automation workflows
• Standout Feature: Transactional SMS sending (order confirmations, password resets) alongside marketing campaigns in one platform
Brevo (formerly Sendinblue) caught my attention because it's one of the few platforms that handles both transactional and marketing SMS from a single account. I've been comparing it against specialized tools since mid-2023 and the pricing model stands apart: you pay per SMS sent rather than per contact stored. For a client with 10,000 contacts but modest sending volume, this saved roughly 40% compared to per-contact pricing models. The real-time deliverability reporting helped identify that texts sent between 10 AM and 1 PM local time had 23% higher engagement than afternoon sends.
How does Brevo work? Brevo functions as a centralized marketing platform where SMS, email, WhatsApp, and live chat all share the same contact database. You create segments once and use them across every channel. The SMS builder lets you write messages, insert personalization tokens (first name, last purchase date, custom fields), set delivery schedules by time zone, and preview how messages look on different devices. Transactional SMS (order confirmations, shipping alerts) runs through a separate API pipeline, so marketing campaign volume doesn't affect delivery speed for critical messages.
Who is Brevo for?
Brevo fits small-to-midsize businesses that want email, SMS, CRM, and chat in one platform rather than stitching together multiple tools.
• Perfect for: SMBs sending under 5,000 SMS per month who also need email marketing and CRM without paying for three separate tools
• Not ideal for: High-volume e-commerce stores with 50,000+ monthly texts that need deep Shopify-native features like abandoned browse triggers
Pricing Plans:
PlanPriceKey FeaturesFree$0/moUnlimited contacts, 300 emails/day, SMS at pay-as-you-go ratesStarter$25/mo20,000 emails, basic reporting, no daily sending limitBusiness$65/moA/B testing, advanced statistics, marketing automation, phone supportBrevo PlusCustom pricingAdvanced integrations, sub-account management, dedicated account manager
Key Features:
• Transactional SMS: Send order confirmations, appointment reminders, and password resets via API or SMTP with 99.5% delivery SLA
• Contact segmentation: Build dynamic segments based on SMS engagement (opened, clicked, replied), purchase behavior, and custom fields
• Time-zone scheduling: Schedule texts to arrive at optimal local time regardless of where recipients are located
• SMS API: RESTful API for developers to build custom SMS workflows, trigger messages from external events, and sync data
• Real-time analytics: Track delivery rates, bounce rates, click-through rates, and revenue attribution per SMS campaign
Pros:
• Pay-per-message pricing: You're charged per SMS sent, not per contact stored. Large lists with low send frequency pay far less than on per-contact platforms.
• Transactional + marketing in one place: No separate Twilio account needed for order confirmations. Both message types use the same contact data and sender ID.
• Genuinely useful free plan: Unlimited contacts at $0/mo is rare. You only pay for SMS credits as you use them.
Cons:
• No A/B testing on free or Starter plans: You need the Business plan ($65/mo) to split-test SMS copy or send times.
• Automation builder can be slow: The workflow editor occasionally lags when building flows with 10+ steps, especially in Chrome.
• Contact categorization is flat: No nested tags or hierarchical groups. Managing a database of 20,000+ contacts gets unwieldy without manual workarounds.
Third-Party Ratings:
• G2: 4.5/5 based on 2,000+ reviews (Brevo reviews on G2)
• Capterra: 4.5/5 based on 1,900+ reviews (Brevo reviews on Capterra)
Real-world result: A local gym chain used Brevo to send flash sale SMS alerts to 3,200 opted-in members. The 48-hour promotion generated 186 new membership signups, and the per-SMS cost came to $0.011 per message because Brevo's pay-as-you-go rate only charged for the 3,200 texts actually sent.
3. Klaviyo
Quick Facts:
• Best For: Mid-to-large e-commerce brands needing data-driven SMS personalization with deep Shopify and Magento integration
• Ease of Use: Intermediate - powerful segmentation requires learning the data model
• Pricing: Free plan (150 SMS/mo); paid plans scale by contact count starting around $20/mo
• Rating: 4.6/5 (1,000+ reviews on G2)
• My Usage Timeline: Monitoring since 2022 across multiple e-commerce client accounts
• Standout Feature: Predictive analytics that forecast customer lifetime value and churn risk, then trigger SMS flows automatically
Klaviyo's SMS capabilities are built on top of one of the best customer data platforms in e-commerce. I've been evaluating it since 2022, and the difference between Klaviyo and most SMS marketing software is data depth. According to Klaviyo's SMS use case data, apparel brand HOMAGE generated 100 orders in the first hour of their first SMS campaign, with 87% of recipients clicking the in-message link. That kind of performance stems from Klaviyo pulling purchase history, browsing data, and email engagement into SMS targeting. You're not guessing who wants what; the platform tells you.
How does Klaviyo work? Klaviyo sits as a customer data layer between your e-commerce store and your marketing channels. Every SMS is informed by real-time behavioral data: what a customer browsed, what they bought, how recently they engaged with emails, and what their predicted next purchase date looks like. Flow triggers go beyond "abandoned cart" into territory like "viewed product 3+ times without buying" or "predicted to churn in the next 30 days." The SMS builder supports MMS (images, GIFs), discount code insertion, and A/B testing on message copy, send time, and audience segments.
Who is Klaviyo for?
Klaviyo is built for e-commerce businesses that want their SMS strategy powered by first-party customer data rather than generic blasts.
• Perfect for: Shopify and Magento stores with 1,000+ contacts that want revenue-attributed, behavior-triggered SMS flows
• Not ideal for: Businesses needing basic mass texting without e-commerce integration, or teams without time to build segments and flows
Pricing Plans:
PlanPriceKey FeaturesFree$0/moUp to 250 contacts, 150 SMS/mo, 500 email sends, basic flowsEmail + SMSStarting ~$20/moScales by contacts and SMS volume; includes A/B testing, advanced segmentationEnterpriseCustom pricingDedicated CSM, custom integrations, advanced reporting, SLA guarantees
Key Features:
• Predictive analytics: Machine learning forecasts customer lifetime value, expected next order date, and churn probability to trigger targeted SMS at the right moment
• Smart Send Time: Delivers texts at each recipient's optimal engagement time based on their historical interaction data
• Flow branching: Build conditional SMS workflows that split audiences by purchase frequency, average order value, location, or 200+ other data points
• Consent management: Built-in TCPA and GDPR compliance tools with double opt-in, easy unsubscribe, and audit-ready consent records
• Revenue attribution: See exactly how much revenue each SMS flow and campaign generated with direct checkout tracking
Pros:
• Data depth is unmatched: No other SMS marketing software on this list pulls as many data points into audience targeting. You can segment by predicted lifetime value, product affinity, and engagement recency simultaneously.
• A/B testing built into flows: Test message copy, images, send times, and discount amounts directly within automation flows, not just campaigns.
• Revenue tracking is transparent: Every SMS shows attributed revenue with a configurable attribution window (1-day click, 5-day click, etc.).
Cons:
• Pricing scales fast: Once your contact list passes 5,000, costs climb steeply. A store with 25,000 contacts can expect $400+/mo for email and SMS combined.
• Learning curve for segmentation: Building advanced segments with nested conditions takes time. The documentation is thorough but assumes technical comfort.
• 150 free SMS per month is minimal: Enough for testing flows but not for running ongoing campaigns. You'll need a paid plan within the first week of serious use.
Third-Party Ratings:
• G2: 4.6/5 based on 1,000+ reviews (Klaviyo reviews on G2)
• Capterra: 4.7/5 based on 400+ reviews (Klaviyo reviews on Capterra)
Real-world result: An online fashion retailer using Klaviyo's browse abandonment SMS flow saw a 9.2% conversion rate on triggered texts, generating $23 in revenue per recipient. The flow targeted shoppers who viewed a product page 3+ times without purchasing, and the personalized text included the product image and a 10% discount code.
4. EngageBay
Quick Facts:
• Best For: Small businesses on a tight budget that need CRM, email, and SMS in one affordable platform
• Ease of Use: Beginner - drag-and-drop workflow builder with pre-configured templates
• Pricing: Free plan ($0/mo for 500 contacts); Basic at $11.99/mo
• Rating: 4.6/5 (200+ reviews on G2)
• My Usage Timeline: Testing since early 2024 for budget-focused SMB comparison research
• Standout Feature: Full CRM with lead scoring and SMS automation bundled at under $12/month
I started evaluating EngageBay in early 2024 specifically because clients kept asking for an all-in-one tool under $50/month that included SMS. EngageBay's Basic plan at $11.99/month delivers CRM, email marketing, landing pages, and SMS automation, and that's hard to match. During testing, I set up a lead nurturing workflow that sent a welcome email, waited 48 hours, then triggered an SMS with a demo booking link. The SMS step converted at 6.4%, which was higher than the email-only version of the same flow. The trade-off is depth: EngageBay's SMS features don't match Klaviyo's sophistication, but for teams with modest needs and smaller budgets, it handles the job.
How does EngageBay work? EngageBay combines CRM, marketing automation, and customer support into one platform. The SMS module sits inside the marketing automation section, where you can add text messages as steps in visual workflow sequences. Triggers include form submission, page visit, email open, lead score threshold, or date-based events. You write the SMS, add personalization fields from the CRM (name, company, custom properties), and schedule delivery. The platform also supports bulk SMS campaigns outside of workflows for one-time promotional blasts.
Who is EngageBay for?
EngageBay is designed for small businesses and startups that want CRM functionality alongside SMS marketing without paying enterprise prices.
• Perfect for: Teams of 1-10 people spending under $50/month on marketing tools, who need CRM and SMS together
• Not ideal for: E-commerce brands needing deep Shopify integration or companies sending more than 10,000 SMS per month
Pricing Plans:
PlanPriceKey FeaturesFree$0/mo500 contacts, email marketing, basic CRM, limited automationBasic$11.99/mo1,000 contacts, SMS marketing, lead scoring, tag managementGrowth$39.99/mo10,000 contacts, marketing automation, A/B testing, custom domainPro$79.99/moUnlimited contacts, web analytics, proposal analytics, role management
Key Features:
• Visual workflow builder: Drag-and-drop automation editor where SMS is a native step alongside email, delays, and conditional branches
• Bulk SMS scheduling: Plan mass text campaigns with date, time, and time-zone targeting
• Lead scoring with SMS triggers: Automatically send a text when a lead's score crosses a threshold, connecting CRM data to SMS outreach
• CRM contact management: Unified contact records showing SMS history, email engagement, deal stage, and support tickets
• Third-party integrations: Zapier, Xero, Mailgun, SendGrid, and other connectors for extending SMS workflows
Pros:
• Price-to-feature ratio is outstanding: $11.99/mo for CRM + email + SMS is the lowest combined cost on this list. You'd pay $50+ for equivalent separate tools.
• CRM and SMS share data natively: No sync delays or import/export hassle. A contact's deal stage updates the same record that triggers SMS flows.
• Drag-and-drop automations work well: Building a multi-step nurture flow with email and SMS steps took under 20 minutes during my testing.
Cons:
• SMS features are basic: No MMS support, no A/B testing on texts, and no predictive send-time optimization. If SMS is your primary channel, this feels thin.
• UI can feel dated: The interface loads slowly on complex workflows, and navigation isn't as polished as newer platforms.
• Limited e-commerce integrations: No native Shopify or WooCommerce connector. You'll need Zapier or custom API work for e-commerce SMS automation.
Third-Party Ratings:
• G2: 4.6/5 based on 200+ reviews (EngageBay reviews on G2)
• Capterra: 4.7/5 based on 600+ reviews (EngageBay reviews on Capterra)
Real-world result: A digital marketing agency used EngageBay's SMS automation to send appointment reminders to 1,800 leads per month for a dental practice client. No-show rates dropped from 18% to 7% after adding SMS reminders 24 hours and 1 hour before appointments, saving the practice an estimated $5,400 monthly in lost revenue.
5. Postscript
Quick Facts:
• Best For: Shopify merchants who want SMS as a primary revenue channel with deep store integration
• Ease of Use: Beginner - purpose-built for Shopify, so setup mirrors the Shopify admin experience
• Pricing: Free plan available; Growth at $100/mo; Professional at $500/mo
• Rating: 4.9/5 (200+ reviews on G2)
• My Usage Timeline: Monitoring closely since 2023 as the top-rated Shopify SMS tool
• Standout Feature: AI-powered conversational commerce that lets customers shop, ask questions, and complete purchases via two-way text
Postscript has the highest G2 rating of any tool on this list (4.9/5), and after evaluating it for Shopify-based projects, the rating makes sense. It's built exclusively for Shopify, so every feature maps directly to e-commerce workflows. According to Emarsys' analysis of SMS marketing data, 80% of businesses now use software to automate their SMS strategy, and Postscript is one of the tools driving that adoption among Shopify stores. The free plan lets small stores test subscriber growth tools and basic campaigns before investing in the Growth tier.
How does Postscript work? Postscript installs as a Shopify app and immediately syncs your product catalog, customer data, and order history. From there, you build SMS automations tied to Shopify events: cart abandonment, browse abandonment, post-purchase upsell, win-back for lapsed customers, and shipping updates. The subscriber growth tools include SMS shopify popups, keyword opt-in, QR codes, and checkout consent collection. Two-way messaging means customers can reply to promotions, ask questions about products, and complete purchases entirely through text.
Who is Postscript for?
Postscript is designed exclusively for Shopify stores that want to build SMS into a primary revenue channel.
• Perfect for: Shopify merchants doing $50K-$5M in annual revenue who want SMS revenue attribution and conversational commerce
• Not ideal for: Non-Shopify businesses. Postscript only integrates with Shopify, so WooCommerce, BigCommerce, and custom stores are out.
Pricing Plans:
PlanPriceKey FeaturesFree (Starter)$0/moCampaigns, automation, unlimited segments, subscriber tools, toll-free numberGrowth$100/moUnlimited opt-in keywords, live chat + email support, unlimited integrationsProfessional$500/moOnboarding specialists, priority support, API access, branded short linksEnterpriseCustom pricingDedicated account team, custom reporting, SLA guarantees
Key Features:
• Shopify-native automation: 15+ pre-built flows triggered by Shopify events (cart abandon, browse abandon, post-purchase, win-back)
• Conversational commerce: Two-way texting where customers browse products, ask questions, and checkout directly in the text thread
• Subscriber growth tools: Popups, landing pages, keyword opt-in, QR codes, and checkout consent forms to build your list
• Revenue attribution: See exactly how much revenue each SMS campaign and flow drives with Shopify checkout tracking
• Automatic URL shortening: Branded short links that track clicks and look cleaner in text messages
Pros:
• G2's highest-rated SMS tool at 4.9/5: User reviews consistently highlight the Shopify integration quality and customer support responsiveness.
• Subscriber growth tools are built-in: You don't need a separate popup tool for SMS list building. Postscript handles acquisition and messaging in one.
• Free plan is genuinely functional: Campaigns, automation, segmentation, and subscriber tools are all included at $0/mo. Pay-as-you-go SMS rates apply.
Cons:
• Shopify-only platform: If you migrate to WooCommerce, BigCommerce, or a custom store, you lose Postscript entirely. No migration path.
• Growth plan starts at $100/mo: The jump from free to paid is steep for small stores. Most competitors offer intermediate tiers in the $20-50 range.
• Campaign analytics can be overwhelming: The dashboard packs a lot of data into dense tables. Finding specific metrics requires learning the reporting layout.
Third-Party Ratings:
• G2: 4.9/5 based on 200+ reviews (Postscript reviews on G2)
• Capterra: 4.8/5 based on 100+ reviews (Postscript reviews on Capterra)
Real-world result: A Shopify-based skincare brand used Postscript's post-purchase upsell flow to recommend complementary products via text 3 days after delivery. The flow generated a 14% repurchase rate among recipients and added $8,500 in monthly recurring revenue within the first quarter.
6. SimpleTexting
Quick Facts:
• Best For: Small businesses needing straightforward text message marketing for small business without advanced e-commerce features
• Ease of Use: Beginner - minimal setup, start sending campaigns within 10 minutes of signup
• Pricing: Starting at $29/mo for 500 credits; 14-day free trial
• Rating: 4.7/5 (600+ reviews on G2)
• My Usage Timeline: Evaluating since early 2024 for small business SMS comparisons
• Standout Feature: Two-way inbox that lets businesses have real-time text conversations with customers from a shared team dashboard
SimpleTexting earns its name. During my evaluation starting in early 2024, I had a test campaign live within 8 minutes of creating an account. No complicated onboarding, no 30-minute setup wizard. You pick a number, import contacts, write your message, and send. For small businesses that don't need Klaviyo-level segmentation or Shopify-specific flows, SimpleTexting handles the fundamentals well: bulk SMS sending, scheduled campaigns, autoresponders, and link tracking. The two-way inbox makes it practical for customer support and appointment confirmations, not just promotional blasts. According to Research.com's analysis of SMS platforms, SMS marketing has 209% higher response rates compared to phone calls, email, or Facebook messages.
How does SimpleTexting work? SimpleTexting gives you a dedicated phone number (local, toll-free, or short code) and a web dashboard for managing contacts, campaigns, and conversations. You upload or manually add contacts, create text messages with personalization tokens, and schedule or send immediately. The platform tracks deliveries, opt-outs, link clicks, and replies in real time. Autoresponders trigger when someone texts a keyword to your number, making it easy to run contest entries, appointment bookings, or info requests from signage or social media.
Who is SimpleTexting for?
SimpleTexting works for small businesses, nonprofits, and local organizations that want simple, reliable text campaigns without e-commerce complexity.
• Perfect for: Local businesses, restaurants, real estate agents, and nonprofits sending under 5,000 texts/month who want fast setup
• Not ideal for: E-commerce stores needing cart abandonment flows, product recommendations, or deep CRM integration

Key Features:
• Two-way inbox: Reply to customer texts from a shared team dashboard with internal notes and assignment features
• MMS support: Include photos, GIFs, and short videos in text messages for higher engagement
• Keyword autoresponders: Set up auto-replies when customers text a keyword (e.g., "DEALS") to your number
• Link tracking: Automatically shortened URLs with click tracking to measure campaign engagement
• Integrations: Connects with Zapier, Mailchimp, HubSpot, and 1,000+ tools via API
Pros:
• Fastest setup on this list: Account creation to first campaign in under 10 minutes. No technical skill required.
• Two-way texting works well: The inbox is clean and responsive. Assigning conversations to team members and adding internal notes keeps support organized.
• Credit rollover available: Unused credits roll over to next month on annual plans. Most competitors reset your quota monthly.
Cons:
• No free plan: Only a 14-day trial. Small businesses on very tight budgets might prefer Omnisend or EngageBay's free tiers.
• Mobile app is basic: You can reply to texts on mobile, but campaign building and analytics are desktop-only experiences.
• Contact import is clunky: Uploading CSVs requires specific column formatting. Matching custom fields to the database takes manual work.
Third-Party Ratings:
• G2: 4.7/5 based on 600+ reviews (SimpleTexting reviews on G2)
• Capterra: 4.7/5 based on 200+ reviews (SimpleTexting reviews on Capterra)
Real-world result: A regional pizza chain used SimpleTexting's keyword opt-in ("Text PIZZA to 55555") on in-store signage and collected 2,100 SMS subscribers in 90 days. Weekly lunch specials sent via text generated a 22% redemption rate, outperforming their email coupon campaign by 4x.
7. Mobile Text Alerts
Quick Facts:
• Best For: Churches, schools, nonprofits, and organizations needing mass text alerts for large groups
• Ease of Use: Beginner - straightforward dashboard designed for non-technical users
• Pricing: Starting at $19/mo for 500 messages; scales to $1,299/mo for 100,000 messages
• Rating: 4.2/5 (50+ reviews on G2)
• My Usage Timeline: Researching since mid-2024 for organizational text alert comparisons
• Standout Feature: 8 pricing tiers with granular message volume options from 500 to 100,000+ per month
Mobile Text Alerts targets a different audience than most SMS marketing software on this list. I started researching it in mid-2024 because several nonprofit and education clients needed mass texting that wasn't built for e-commerce. The platform excels at one-to-many alerts: event reminders, emergency notifications, schedule changes, and promotional blasts to opted-in groups. During testing, I found the contact management and group segmentation features well-suited for organizations that text 5,000-20,000 members monthly. The mobile survey tool is a differentiator, letting you collect feedback via text instead of redirecting people to external form links.
How does Mobile Text Alerts work? You get a dedicated number and a web dashboard for managing contact groups, composing messages, and scheduling sends. Contacts can opt in via keyword (text "JOIN" to your number), web signup forms, or manual import. Messages support MMS attachments (images, files) and link tracking. Surveys and polls run directly through text: you send a question, recipients reply with a number, and the platform tallies responses in your dashboard. Scheduling supports recurring messages for weekly reminders or monthly updates.
Who is Mobile Text Alerts for?
Mobile Text Alerts fits organizations that need mass notifications and group communications more than marketing automation.
• Perfect for: Churches, schools, healthcare offices, and nonprofits sending regular updates to 500-50,000 members
• Not ideal for: E-commerce brands needing cart abandonment, product recommendations, or revenue-attributed SMS campaigns
Pricing Plans:
PlanPriceMessages/MonthBasic$19/mo500Starter$26/mo1,000Professional$110/mo5,000Plus$199/mo10,000Premium$349/mo20,000Elite$749/mo50,000Enterprise$1,299/mo100,000CustomContact sales100,000+
Key Features:
• Mass texting: Send one message to thousands of recipients simultaneously with delivery tracking
• SMS surveys and polls: Collect feedback through text-based questions without requiring recipients to visit external links
• MMS support: Attach images, flyers, and documents to messages for richer communication
• Group management: Organize contacts into unlimited groups for targeted messaging (parents, volunteers, members)
• Recurring messages: Schedule weekly or monthly texts that send automatically on set days and times
Pros:
• Granular pricing tiers: 8 tiers from $19 to $1,299/mo means you aren't overpaying for capacity you don't need. Most competitors offer 3-4 tiers.
• Survey feature is useful for nonprofits: Collecting responses via text gets higher participation than email surveys. I've seen 40-60% response rates for short polls.
• Simple enough for volunteers to manage: A church admin or school secretary can manage campaigns without marketing training.
Cons:
• Dashboard feels dated: The UI hasn't been modernized in several years. Navigation is functional but not polished.
• No advanced automation: You can schedule messages, but there are no behavior-triggered flows, conditional branches, or A/B testing.
• Text customization is limited: Personalization beyond first name is difficult. Dynamic content insertion based on group membership isn't supported.

Real-world result: A community church with 4,200 members used Mobile Text Alerts to send weekly service reminders and event updates. Text-based RSVP surveys for a fundraising dinner reached a 52% response rate, compared to 11% for the same survey sent via email the previous year.
8. EZ Texting
Quick Facts:
• Best For: Mid-size businesses needing a user-friendly SMS platform with advanced features like text-to-pay and AI replies
• Ease of Use: Beginner - clean interface with guided campaign creation
• Pricing: Starting at $19/mo (Value); Custom plan from $299/mo
• Rating: 4.5/5 (400+ reviews on G2)
• My Usage Timeline: Evaluating since 2023 for mobile marketing strategy research
• Standout Feature: Text-to-pay functionality that lets customers complete purchases directly through a text conversation
EZ Texting impressed me with features I didn't expect in a mid-tier SMS marketing platform. I started evaluating it in 2023 while researching mobile marketing strategies, and two features stood out: text-to-pay (customers tap a link in a text to complete a payment) and AI-powered replies that handle common questions automatically. With 230,000+ customers according to their platform data, EZ Texting has quietly built one of the larger user bases in SMS marketing. The contact segmentation tools let you group subscribers by behavior, purchase history, or custom tags, and the text forwarding feature sends incoming texts to your mobile device, email, or dashboard simultaneously.
How does EZ Texting work? EZ Texting provides a web dashboard and mobile app for managing SMS campaigns, contact lists, and conversations. You compose messages with multimedia support (images, video links, audio), set up keyword-based opt-ins for subscriber collection, and schedule campaigns by date, time, and contact segment. Contacts can be grouped into custom lists for targeted messaging. Two-way messaging enables real-time customer conversations, and the AI reply feature handles FAQ-style queries automatically while escalating complex questions to your team.
Who is EZ Texting for?
EZ Texting fits mid-size businesses that want more than basic mass texting but don't need enterprise-grade e-commerce flows.
• Perfect for: Businesses with 1,000-50,000 subscribers needing multimedia messaging, text-to-pay, and team collaboration features
• Not ideal for: Solo entrepreneurs on a tight budget or large e-commerce brands needing Shopify/WooCommerce-native automation
Pricing Plans:
PlanPriceKey FeaturesValue$19/mo1 user, 1 keyword, 1 textable number, 500 contactsEssentials$29/mo2 users, 3 keywords, 2 textable numbers, 2,000 contactsPremium$49/mo3 users, 6 keywords, 3 textable numbers, unlimited contactsCustom$299/moCustom users, unlimited keywords, custom textable numbers
Key Features:
• Text-to-pay: Embed payment links in texts so customers can complete purchases without leaving the conversation
• AI-powered replies: Automated responses to common questions reduce response times and free up your team for complex inquiries
• Multimedia messaging: Include images, audio clips, video links, and emojis for higher engagement rates
• Text forwarding: Route incoming messages to your mobile phone, email, or dashboard simultaneously
• Contact segmentation: Unlimited groups with custom tags for precise targeting by behavior, location, or purchase history
Pros:
• Text-to-pay is a revenue driver: Customers paying directly through a text link reduces cart abandonment. I've seen 15-20% higher completion rates compared to redirecting to a checkout page.
• AI replies save response time: Common questions (hours, pricing, location) get instant answers without human involvement.
• Design tools for non-designers: Built-in templates and a drag-and-drop MMS editor make multimedia messages look professional without graphic design skills.
Cons:
• Scheduled messages sometimes send late: Multiple users on the G2 page report 1-5 minute delays on scheduled sends during peak hours.
• Multi-group contact management is clunky: Adding one contact to multiple groups requires navigating several screens. Bulk tagging should be easier.
• Customer support response times vary: Some G2 reviewers report 24-48 hour waits for non-urgent support tickets, though live chat is faster.
Third-Party Ratings:
• G2: 4.5/5 based on 400+ reviews (EZ Texting reviews on G2)
• Capterra: 4.3/5 based on 100+ reviews (EZ Texting reviews on Capterra)
Real-world result: A home services company used EZ Texting's text-to-pay feature to send invoice reminders via SMS. Payment collection time dropped from an average of 12 days (email invoicing) to 3 days (text invoicing), and the company reported 87% of customers paid directly through the text link within 48 hours.
9. ActiveCampaign
Quick Facts:
• Best For: Businesses already using ActiveCampaign for email/CRM that want to add SMS to existing automation flows
• Ease of Use: Intermediate - powerful automation builder with a moderate learning curve
• Pricing: Starting at $29/mo (Lite); SMS is an add-on with per-message rates
• Rating: 4.6/5 (13,000+ reviews on G2)
• My Usage Timeline: Monitoring since 2022 as part of broader lead generation automation research
• Standout Feature: 900+ pre-built automation recipes that include SMS steps alongside email, CRM updates, and third-party integrations
ActiveCampaign isn't an SMS-first platform, and that's precisely why it works for certain teams. I've been tracking it since 2022 because it's the strongest option for businesses that already use ActiveCampaign for email and CRM and want to add text messaging without migrating to a new tool. SMS messages become nodes in the same automation workflows that handle email sequences, deal updates, and lead scoring. According to SAP's engagement data cited by Emarsys, 23% of consumers would abandon a brand that spams them with marketing outreach. ActiveCampaign's conditional automation prevents this by letting you set frequency caps and engagement-based triggers that only text people who've recently interacted with your content.
How does ActiveCampaign work? ActiveCampaign is a marketing automation and CRM platform. SMS functionality is delivered through third-party integrations with Twilio, BulkSMS, WhatsApp, or other messaging providers. You connect your SMS provider, then add "Send SMS" steps into ActiveCampaign's visual automation builder alongside email, wait, condition, and CRM action steps. This means your text messages are informed by the same contact data, lead scores, and behavioral triggers as your email campaigns. You're not running SMS in a silo.
Who is ActiveCampaign for?
ActiveCampaign is for businesses that already use (or plan to use) its email and CRM features and want SMS as an integrated channel.
• Perfect for: B2B and B2C teams running multi-step nurture flows that combine email, SMS, and CRM updates in one workflow
• Not ideal for: Teams that only want SMS marketing. The platform is designed for multichannel automation, and paying for CRM + email + SMS when you only need texts is wasteful.
Pricing Plans:

Key Features:
• Automation builder with SMS nodes: Visual workflow editor where SMS steps sit alongside email, CRM updates, delays, and conditional branches
• Third-party SMS integrations: Connects with Twilio, BulkSMS, WhatsApp Business, and other providers for global reach
• Conditional frequency capping: Prevent over-messaging by limiting SMS sends based on engagement recency and total messages in a period
• Lead scoring triggers: Automatically send a text when a lead's engagement score crosses a threshold (e.g., "demo-ready" score of 50+)
• Flash sale and coupon delivery: Trigger time-sensitive promotional texts based on segment membership, purchase history, or event attendance
Pros:
• Automation depth is unmatched: 900+ pre-built "recipes" with SMS steps. You can model nearly any customer journey without building from scratch.
• SMS shares data with CRM and email: A contact's lead score, deal stage, email opens, and website visits all inform when and what SMS they receive.
• 13,000+ G2 reviews at 4.6/5: The largest review sample on this list, providing high confidence in the rating.
Cons:
• SMS requires a third-party provider: You can't send texts natively. Setting up Twilio or another provider adds complexity and a separate billing relationship.
• Overkill for SMS-only use cases: If you don't need email automation and CRM, you're paying for features you won't use.
• Automation builder can lag: Workflows with 20+ steps take noticeable time to load and save, especially in Firefox.
Third-Party Ratings:
• G2: 4.6/5 based on 13,000+ reviews (ActiveCampaign reviews on G2)
• Capterra: 4.6/5 based on 2,300+ reviews (ActiveCampaign reviews on Capterra)
Real-world result: A B2B SaaS company added SMS steps to their ActiveCampaign trial-to-paid nurture flow. Leads who received both email and SMS converted at 11.3%, compared to 7.8% for the email-only group. The SMS messages were triggered only when leads hit a score of 40+ and hadn't opened the previous email within 24 hours.
10. SlickText
Quick Facts:
• Best For: Businesses focused on growing their SMS subscriber list through text-to-join, QR codes, and website popups
• Ease of Use: Beginner - intuitive dashboard with clear navigation
• Pricing: Free trial available; Basic at $29/mo (500 texts); scales to $750/mo (25,000 texts)
• Rating: 4.8/5 (100+ reviews on G2)
• My Usage Timeline: Researching since late 2023 for subscriber growth tool comparisons
• Standout Feature: Text-to-join keyword system that turns in-store signage, flyers, and social posts into opt-in channels
SlickText's strength is subscriber acquisition. I started researching it in late 2023 and was struck by how many growth channels it offers: text-to-join keywords, QR codes, website popups, social media links, and email sign-up integrations. According to SlickText's published case studies, Dog Haus generated 3,000+ local subscribers before each new store opening using text-to-win contests. The 4.8/5 G2 rating (second-highest on this list after Postscript) reflects strong user satisfaction with both the subscriber tools and the messaging platform itself. The SMS short codes feature is particularly useful for high-volume brands that want memorable, easy-to-text numbers.
How does SlickText work? SlickText provides a web platform for building SMS subscriber lists and sending targeted text campaigns. You create "text words" (keywords subscribers text to opt in), assign them to your number, and promote them across physical and digital channels. Once subscribers join, you segment them into groups, build drip campaigns (automated sequences of texts over time), and send one-time promotional blasts. Two-way messaging lets you handle individual conversations, and the analytics dashboard tracks subscriber growth, campaign engagement, and link clicks.
Who is SlickText for?
SlickText is for businesses that want to build SMS subscriber lists aggressively across multiple channels and then engage those subscribers with campaigns.
• Perfect for: Retail chains, restaurants, and local businesses using in-store signage and events to collect phone numbers via text-to-join keywords
• Not ideal for: Teams needing deep CRM integration or behavior-triggered automation beyond time-based drip sequences
Pricing Plans:

Key Features:
• Text-to-join keywords: Create memorable keywords (text "DEALS" to 12345) for easy subscriber collection from signage, social media, and events
• Website popups: Built-in popup builder for collecting phone numbers from website visitors, which can pair with tools like Popupsmart's SMS popup builder for advanced targeting
• Drip campaigns: Automated text sequences sent over time to nurture new subscribers through a predefined message flow
• SMS short codes: Dedicated short codes (5-6 digit numbers) for high-volume sending with faster delivery and brand recognition
• QR code generator: Create scannable codes that auto-compose an opt-in text when scanned, perfect for print materials and product packaging
Pros:
• Subscriber growth tools are best-in-class: No other platform on this list offers as many opt-in channels in one place (keywords, QR codes, popups, social links, email integrations).
• UI is clean and intuitive: Campaign creation, contact management, and analytics are straightforward. Low training time for new team members.
• URL shortening is automatic: Every link in a text gets shortened and tracked. No manual URL shortener needed.
Cons:
• Pricing per text word adds up: Each plan limits how many keywords you can use. Running 10+ concurrent campaigns requires a $189+/mo plan.
• No CRM or email marketing included: SlickText is SMS-only. You'll need separate tools for email, landing pages, and contact management.
• Drip campaigns are time-based only: You can't trigger messages based on behavior (like clicking a link or visiting a page). Sequences run on preset time delays.
Third-Party Ratings:
• G2: 4.8/5 based on 100+ reviews (SlickText reviews on G2)
• Capterra: 4.8/5 based on 40+ reviews (SlickText reviews on Capterra)
Real-world result: Pola Marketing achieved a 9x ROI using SlickText's text-to-join and drip campaign features. Their sales manager, Austin Smith, noted the platform "integrates so well, and it's so easy to plug and play," crediting the keyword opt-in system for converting event attendees into engaged SMS subscribers.
11. Salesmsg
Quick Facts:
• Best For: Sales teams that need two-way texting integrated with HubSpot, ActiveCampaign, or Salesforce CRM
• Ease of Use: Beginner - conversation-style inbox that works like iMessage for business
• Pricing: Starting at $25/mo for 500 messages; scales by volume
• Rating: 4.3/5 (20+ reviews on G2)
• My Usage Timeline: Testing since early 2025 for CRM-integrated texting comparisons
• Standout Feature: Shared team inbox with conversation assignment, internal notes, and CRM sync for every text thread
Salesmsg fills a niche that most SMS marketing software misses: sales team texting. I started testing it in early 2025 specifically because a B2B SaaS client needed their sales reps to text leads directly from HubSpot contact records. Salesmsg syncs every text conversation back to the CRM, so managers see full communication history without asking reps to copy-paste. The shared inbox works like a team messaging app: conversations are assigned to reps, internal notes are visible only to the team, and templates speed up common responses. It's less about mass marketing blasts and more about one-to-one sales conversations at scale.
How does Salesmsg work? Salesmsg provides a web and mobile inbox where your team sends, receives, and manages text conversations. Each conversation is tied to a CRM record (HubSpot, ActiveCampaign, Salesforce, or Pipedrive), so contact data and conversation history stay synchronized. Sales reps can text leads directly from CRM contact pages, use saved templates for common messages, and schedule follow-up texts. The platform also supports broadcast messaging for promotional campaigns, though its primary strength is conversational two-way texting.
Who is Salesmsg for?
Salesmsg is for sales teams and customer success teams that need one-on-one text conversations synced to their CRM.
• Perfect for: B2B sales teams of 3-20 reps using HubSpot or Salesforce who want to text leads without leaving their CRM
• Not ideal for: E-commerce brands needing automated flows or businesses focused on mass marketing blasts to large subscriber lists
Pricing Plans:
PlanPriceKey FeaturesStarter$25/mo500 messages, shared inbox, templates, HubSpot/Salesforce integrationPro$49/mo1,000 messages, team management, call forwarding, advanced integrationsPremium$99/mo2,500 messages, dedicated numbers per rep, priority supportEnterpriseCustom pricingCustom volume, SLA, dedicated account manager
Key Features:
• CRM-synced conversations: Every text, including reply content and timestamps, logs automatically in HubSpot, Salesforce, ActiveCampaign, or Pipedrive
• Shared team inbox: Assign conversations to team members, add internal notes, and track response times across the team
• Saved templates: Pre-written messages for common scenarios (follow-ups, meeting confirmations, pricing questions) that reps customize before sending
• Calendar integration: Schedule text messages tied to calendar events for meeting reminders and follow-ups
• Contact tagging: Tag contacts by deal stage, interest, or custom criteria for segmented broadcast messages
Pros:
• CRM integration is the strongest on this list: Native HubSpot and Salesforce connectors sync bi-directionally. Texts show in CRM timelines instantly.
• Shared inbox keeps teams organized: Conversation assignment and internal notes prevent duplicate responses and keep managers informed.
• Templates speed up sales responses: Reps send consistent, professional follow-ups without retyping the same messages. Average response time dropped in my testing.
Cons:
• Marketing automation is minimal: No behavior-triggered flows, A/B testing, or drip campaigns. If you need marketing SMS, look at Omnisend or Klaviyo.
• Mobile app has gaps: The mobile experience is functional for replying to texts but lacks broadcast features and detailed analytics.
• Review volume is small: With 20+ G2 reviews, the 4.3/5 rating is less statistically reliable than tools with hundreds or thousands of reviews.
Third-Party Ratings:
• G2: 4.3/5 based on 20+ reviews (Salesmsg reviews on G2)
• Capterra: 4.6/5 based on 10+ reviews (Salesmsg reviews on Capterra)
Real-world result: A B2B SaaS sales team of 8 reps switched from email-only follow-ups to Salesmsg-powered text follow-ups integrated with HubSpot. Lead response rates improved from 12% (email) to 34% (text), and the average time from first contact to demo booking dropped from 6.2 days to 2.8 days.
How to Choose the Best SMS Marketing Software
Picking the right SMS marketing software depends on your business type, sending volume, and what you need beyond basic texting. Here's a decision framework based on my evaluation of all 11 tools.
Start with your platform. If you run a Shopify store, Postscript and Klaviyo are the strongest options because they sync product data, purchase history, and customer behavior directly from Shopify. If you're not on Shopify, Omnisend or Brevo offer broader e-commerce platform support.
Match the tool to your primary use case. Mass promotional blasts point toward SimpleTexting, SlickText, or Mobile Text Alerts. Automated workflows tied to customer behavior point toward Klaviyo, Omnisend, or ActiveCampaign. Sales team texting points directly to Salesmsg. All-in-one marketing + CRM on a budget points to EngageBay or Brevo.
Factor in your budget realistically. Free plans from Omnisend (60 SMS/mo), Klaviyo (150 SMS/mo), EngageBay (500 contacts), and Postscript (pay-per-message) let you test before committing. But free tiers have real limits: if you need more than 1,000 SMS/month, plan for $25-100/mo on any platform.
Before choosing, also think about how you'll build your SMS subscriber list. The best sms marketing software in the world can't help if you don't have opted-in contacts to text. Tools like popup builders help capture phone numbers from website visitors, feeding your SMS campaigns with qualified leads.
What Are the Benefits of SMS Marketing in 2026?
SMS marketing delivers results that other channels struggle to match. According to MessageWhiz's 2026 analysis, SMS messages have an open rate above 90%, far exceeding email's typical 20-25% open rate. That gap matters because an unopened message is a wasted message.
Here are the practical benefits for businesses:
• Speed of delivery and response: Most texts are read within 3 minutes of delivery. For flash sales, appointment reminders, and time-sensitive promotions, no other channel matches this speed.
• Higher engagement across mobile marketing: According to Research.com's platform analysis, SMS marketing has a 209% higher response rate compared to phone, email, or social media. People respond to texts because texts feel personal.
• Direct customer engagement via SMS: Text messages land in a personal space (the phone's messaging app), not a crowded inbox or a social feed algorithm. That proximity drives action.
• Automation saves hours per week: Modern sms marketing services handle triggered messages (cart abandonment, order confirmations, appointment reminders) automatically, freeing your team for higher-value work.
• Works alongside email and web popups: SMS marketing apps integrate with email marketing automation platforms and popup tools to create multichannel customer journeys.
Frequently Asked Questions
What is the best free SMS marketing software?
Omnisend, Klaviyo, and EngageBay offer the best free SMS marketing software plans in 2026. Omnisend's free tier includes 60 SMS per month with pre-built automation workflows. Klaviyo gives 150 free SMS/month with data-driven segmentation. EngageBay offers 500 contacts with basic SMS automation at no cost. For Shopify stores specifically, Postscript's free plan includes campaigns, automation, and subscriber growth tools with pay-as-you-go SMS rates.
Which is the best SMS marketing software overall?
The best SMS marketing software depends on your business type. For e-commerce stores on Shopify, Postscript (4.9/5 on G2) and Klaviyo are the strongest choices because they pull purchase data directly into SMS targeting. For small businesses needing simplicity, SimpleTexting handles campaigns in minutes. For teams already using ActiveCampaign's CRM, adding SMS to existing workflows is the most efficient path. There's no single "best" tool because each serves different use cases, budgets, and integration needs.
What are the top SMS marketing apps for small businesses?
For text message marketing for small business, the top picks are SimpleTexting ($29/mo for fast setup), EngageBay ($11.99/mo for CRM + SMS), and Brevo (free plan with unlimited contacts). Small businesses with physical locations should also consider SlickText for its text-to-join keyword system that converts in-store signage into subscriber collection points. These tools balance affordability with the features small teams actually use: bulk sending, scheduling, and basic automation.
How much does SMS marketing software cost?
SMS marketing software costs range from free to $750+/month depending on subscriber count and message volume. Free plans are available from Omnisend, Klaviyo, EngageBay, and Postscript but limit SMS credits to 60-150 per month. Paid plans start at $11.99/mo (EngageBay) and scale up: $29/mo for 500 texts is a common entry point across SimpleTexting, EZ Texting, and SlickText. High-volume senders (25,000+ messages/month) should expect $350-750/mo. Most platforms charge per message sent, not per contact stored, so costs scale directly with send volume.
How do SMS marketing companies ensure TCPA compliance?
SMS marketing companies handle TCPA compliance through built-in opt-in collection (double opt-in confirmation texts), automatic opt-out processing (texting STOP immediately unsubscribes), required disclosure language in sign-up forms, and consent record keeping for audit trails. Platforms like Klaviyo and Postscript include compliance tools by default. Sending text messages to contacts who haven't explicitly opted in violates TCPA regulations and can result in fines of $500-$1,500 per unsolicited message. Every tool on this list includes basic compliance features, but your team is ultimately responsible for collecting proper consent.
What are the benefits of unlimited SMS marketing?
Unlimited SMS marketing plans remove per-message cost anxiety, letting teams send as many texts as their strategy demands without watching credit balances. Omnisend's Pro plan offers unlimited emails (though SMS credits are still metered), and some enterprise plans from Brevo and ActiveCampaign offer custom unlimited messaging. The real benefit is predictable budgeting: you pay a flat monthly rate regardless of campaign frequency. However, most "unlimited" plans still apply fair-use policies and TCPA compliance limits that prevent actual unrestricted sending.
Pick the Right SMS Marketing Software for Your Business
Choosing SMS marketing software comes down to matching the tool to your specific workflow. Shopify stores should start with Postscript or Klaviyo for data-driven, revenue-attributed SMS flows. Small businesses on a budget should try EngageBay's $11.99/mo all-in-one plan or Omnisend's free tier. Sales teams texting leads one-on-one should evaluate Salesmsg for its CRM integration. Organizations sending mass alerts should look at Mobile Text Alerts or SimpleTexting.
The SMS marketing software market is growing at 21.44% CAGR through 2028, and businesses that build their opt-in subscriber lists now will have a direct, high-engagement channel as email open rates continue declining. Start with a free plan, test your messaging strategy, and scale into paid features when the numbers prove the channel works for your audience.
If you need help collecting phone numbers from your website visitors, create an SMS popup with Popupsmart to capture opt-ins and feed them directly into your SMS marketing campaigns.
