Switching from OptinMonster to Popupsmart

We move your campaigns for you

  • Free campaign migration: our team rebuilds your OptinMonster popups in Popupsmart.
  • 2 hours of consultancy on your campaigns, free: a $300 value.
Book your free migration

What carries over

  • Your email list and CRM stay where they are: Popupsmart sends each lead to Klaviyo, Mailchimp, HubSpot and its other integrations on every plan.
  • On WordPress, Popupsmart's optional plugin adds its snippet; on any other site, one line of code does.

What you rebuild

  • Popups don't carry over between tools, so each campaign is rebuilt: our team does it for free, or you rebuild it yourself from a template or with the Popupsmart AI agent.
  • Targeting rules, schedules and frequency caps are set again; exit intent, location and the other display rules are on every plan, the free one included.

What else you need

  • A/B testing starts on Popupsmart's Advanced plan; OptinMonster includes it from Plus.
  • Inline and sidebar forms and content lockers have no Popupsmart equivalent; if your site relies on them, compare them first in Popupsmart vs OptinMonster.

Also considered, not yet listed

  • Wisepops and Alia: Wisepops is a managed service priced for large stores, and Alia runs on Shopify only. Neither fits a WordPress site collecting leads, so we left them off this list.
  • Klaviyo forms and Mailchimp forms: Signup forms built into an email platform. They're free with it but aren't popup builders, so we haven't compared them here.
  • OptinMonster's own higher plans: If exit intent or location targeting is what you're missing, Pro adds exit intent and traffic-source targeting, and Growth adds location and new-visitor targeting.

How we made this list

We make Popupsmart, one of the tools on this list, and list it first. The picks and the entries say where each other tool fits better, and where OptinMonster itself is the better choice.

Prices and free plans come from each vendor's own pricing page, read on the dates shown beside each tool; OptinMonster's on 26 Sep 2026. Where a vendor bills impressions, visitors or list size rather than pageviews, the table says so and converts nothing. Popupsmart's figures come from our pricing page.

Reviews: an AI assistant read every G2 review of each product and sorted what the reviewers praise and criticise into themes; the counts are reviews per theme, out of all the reviews read. No person has checked every tag. Sleeknote has too few G2 reviews to read alone, so we also read its Capterra and Trustpilot reviews. Mailmunch has no G2 reviews, so its entry gives its WordPress.org rating and no theme counts. Review sites mix organic reviews with ones the vendor invited; each product's reviews say which.

The screenshots are ours, of each vendor's home page while logged out, and each caption gives the day it was taken.

Frequently asked questions

What is the best OptinMonster alternative?
The best OptinMonster alternative depends on why you're leaving. If your team has no developer and wants campaigns live the same day, built by hand or by the Popupsmart AI agent, with exit intent and every integration on every plan, Popupsmart. For a WordPress site on a budget, Popup Maker's free plugin. For every feature on a free plan, OptiMonk or Claspo. For embedded forms and email from one company, Poptin. For ecommerce teams with many websites, Sleeknote. For popups, email and SMS in one app, Privy. For forms, landing pages and email in one tool with a WordPress plugin, Mailmunch.
Is there a free alternative to OptinMonster?
OptinMonster has no free plan, only a 14-day money-back guarantee. OptiMonk (10,000 pageviews a month), Popupsmart (5,000 pageviews), Claspo (3,000 pageviews) and Poptin (1,000 visitors) all start free, and Popup Maker's core plugin is free with no traffic limit, on WordPress only. Mailmunch's free plan covers forms, popups and landing pages with its branding. Sleeknote and Privy offer a trial instead.
Which OptinMonster plan includes exit intent?
OptinMonster includes exit intent on Pro and Growth, its two higher plans; Basic and Plus don't include it. Location and new-visitor targeting come only with Growth. Popupsmart puts exit intent, location, traffic-source and new-visitor targeting on every plan, the free one included. OptiMonk and Claspo put every feature on every plan, and Popup Maker adds exit intent with Pro, $99 / yr for one site.
How do OptinMonster's prices compare as traffic grows?
OptinMonster bills campaign impressions and its pricing FAQ advises a plan with 20–30% more impressions than your pageviews. Its smallest plan is $21 a month for 2,500 impressions, and above 100,000 impressions it quotes a custom plan. Sized that way, Popupsmart costs less at every traffic level we compared on monthly billing, and from the second year on annual billing, when OptinMonster renews at full price; OptinMonster's first annual year costs less at several levels. The full price table is in Popupsmart vs OptinMonster.
Can I move my OptinMonster popups to another tool?
OptinMonster popups don't carry over to any of these tools, so each campaign is rebuilt. If you move to Popupsmart, our team rebuilds your OptinMonster campaigns for free and adds 2 hours of consultancy on them (a $300 value). With the other tools you rebuild each one yourself, from a template. Your email list stays in your email platform, so connecting the new tool to it keeps new leads going to the same place.
Why do people look for OptinMonster alternatives?
In our reading of every OptinMonster review on G2, the complaints are a learning curve and an editor that can confuse, missing features such as form fields and display logic, the price for small businesses with features kept for higher plans, and reporting detail. Its reviewers praise its ease of use and the leads and sales it brings in, and most of those reviews were written between 2019 and 2023. Ease of use is also what Popupsmart's reviewers praise most, in our reading of its 141 G2 reviews.
