Justuno is a conversion rate optimization platform used by ecommerce teams to grow email and SMS lists, recommend products, and lift average order value. It is a capable suite, but businesses look for alternatives for two recurring reasons: the learning curve on advanced targeting rules, and pricing that starts at $59 per month with no free plan to grow into.
Platforms like Popupsmart, OptinMonster, Privy, BDOW!, and Hello Bar take different approaches to onsite lead generation. Below we review five Justuno alternatives in 2026, comparing their key features, pricing, and limitations so you can pick the popup builder that fits your website.
We've been working with popup builders for more than six years and have tested many of these tools across real marketing campaigns. The list below reflects our hands-on experience with popup campaigns and conversion optimization.
1. Popupsmart

Popupsmart is the most practical Justuno alternative for teams that want strong targeting without the setup overhead of a full CRO suite. Marketers launch campaigns without developers, and the free plan means you can validate a campaign before you pay for anything.
Some of the features of Popupsmart:
• Exit-intent popups, floating bars, slide-ins, and embedded forms
• Advanced targeting by behavior, device, traffic source, and location
• No-code editor with 350+ customizable templates and an AI popup builder
• Gamified popups, cookie consent templates, and multi-step forms
• Unlimited campaigns on paid plans, with A/B testing from the Advanced plan
• Native integrations with Klaviyo, Salesforce, HubSpot, Mailchimp, ActiveCampaign, and more
Price: Free forever plan with every campaign type and targeting option included, so small websites and startups can run real campaigns without paying. Paid plans start at $39 per month and cost $69 per month at 100,000 pageviews, or $32.5 and $57.5 on annual billing.
Compared with Justuno, Popupsmart trades CRO-suite depth for speed and cost, and at 100,000 traffic it runs about a quarter of the price. Teams that want a targeted popup live today, rather than a platform to administrate, consistently choose it over heavier tools.
2. OptinMonster

OptinMonster is one of the most widely used popup builders for lead generation and conversion optimization, and a common cross-shop against Justuno for content sites and WordPress publishers.
Below are the primary features of OptinMonster:
• Exit-intent popups and scroll-based triggers
• Drag-and-drop campaign builder
• Advanced targeting and segmentation rules
• A/B testing and analytics
• Integrations with major email marketing platforms
Price: OptinMonster offers several pricing tiers depending on traffic and feature requirements, with no free plan.
Compared with Justuno, OptinMonster is less ecommerce-specific and more oriented toward general lead generation. Businesses comparing Justuno alternatives often evaluate it alongside Popupsmart when segmentation matters more than product recommendations.
3. Privy

Privy is a marketing platform built primarily for ecommerce businesses that want to grow email lists and drive sales through popups plus email and SMS campaigns.
Below are the primary features of Privy:
• Email capture popups and announcement bars
• Exit-intent and cart-based triggers
• Drag-and-drop campaign builder
• Email and SMS marketing automation
• Integrations with Shopify and other ecommerce platforms
Price: Privy offers a free plan with limited features and paid plans that scale with contacts and email volume.
Compared with Justuno, Privy bundles the messaging channel with the popup, which suits stores that want capture and follow-up in one tool. Shopify merchants often shortlist it alongside Popupsmart when comparing Justuno alternatives.
4. BDOW! (formerly Sumo)

BDOW!, formerly Sumo, is a conversion optimization tool that helps websites grow email lists through popups, forms, and onsite messages.
Some of the features of BDOW! include:
• Email capture popups and opt-in forms
• Scroll-trigger and exit-intent targeting
• Drag-and-drop popup builder
• Basic analytics and reporting
• Integrations with email marketing platforms
Price: BDOW! offers a free plan with limited features, while paid plans unlock additional campaign options and integrations.
Compared with Justuno, BDOW! is deliberately simpler and covers list growth without the CRO machinery. It is a reasonable fit for content sites and small stores that found Justuno heavier than they needed.
5. Hello Bar

Hello Bar is a conversion tool that helps websites capture leads and drive engagement through bars, popups, and simple onsite messaging.
Below are the primary features of Hello Bar:
• Top bars, sliders, modals, and page overlays
• Drag-and-drop campaign builder
• Basic targeting and trigger options
• Email capture forms and call-to-action buttons
• Integrations with email marketing platforms
Price: Hello Bar offers a free plan with limited features, while paid plans unlock additional targeting options and campaign capabilities.
Compared with Justuno, Hello Bar focuses on lightweight announcement and capture elements rather than full conversion programs. Businesses evaluating Justuno alternatives often consider it alongside Popupsmart when the goal is a single, simple onsite message.
