We move your campaigns for you

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 Shopify, discount codes stay in Shopify: Popupsmart can hand each visitor a unique code, show a product feed in the popup and target by what's in the cart.

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 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; OptiMonk includes it on every plan.
  • If your store relies on OptiMonk's product recommendations and revenue per campaign, compare them first in Popupsmart vs OptiMonk.

Only 6 reviews on G2: too few to count themes.

Reviews written 2019–2026, 1 in the 12 months before we read them

Also considered, not yet listed

  • Justuno, Hello Bar and ConvertFlow: Not listed: we haven't read every one of their reviews yet, so there's no reading to set beside the others.
  • Klaviyo forms and Shopify Forms: Signup forms built into an email platform and into Shopify. They're free with those platforms but aren't popup builders, so we haven't compared them here.
  • OptiMonk's own paid plans: If the free plan is what you've outgrown, its paid plans keep every feature and start at $19 / mo for 20,000 pageviews.

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 OptiMonk 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; OptiMonk's on 22 Sep 2026. Where a vendor bills visitors or impressions 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. Alia has no G2 page, so its entry gives its Shopify App Store 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 OptiMonk alternative?
The best OptiMonk 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, and on several websites, Popupsmart. For popups with email and SMS in one app, Privy. For a Shopify store that wants AI or a team to run its popups, Alia. For campaigns a strategist builds for you, Wisepops. For forms inside your pages, OptinMonster. For a WordPress site on a budget, Popup Maker's free plugin. For the same all-features model with a free plan, Claspo.
Is there a free alternative to OptiMonk?
OptiMonk's own free plan is the biggest of the hosted tools here, at 10,000 pageviews a month. Popupsmart (5,000 pageviews), Claspo (3,000 pageviews) and Poptin (1,000 visitors) also start free, and Popup Maker's core plugin is free with no traffic limit, on WordPress only. Privy, Alia, Wisepops, OptinMonster and Sleeknote don't: they offer a trial or a money-back guarantee instead.
How do OptiMonk's prices compare as traffic grows?
OptiMonk starts at $19 / mo for 20,000 pageviews and is the cheaper of the two up to 30,000 pageviews a month. From 30,000 to 500,000, Popupsmart costs less or the same and covers more websites on each plan. The full price table is in Popupsmart vs OptiMonk.
Can I move my OptiMonk popups to another tool?
OptiMonk popups don't carry over to any of these tools, so each campaign is rebuilt. If you move to Popupsmart, our team rebuilds your OptiMonk 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 or, in OptiMonk, with its AI agent. 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 OptiMonk alternatives?
In our reading of every OptiMonk review on G2, the complaints are an editor that can be hard to handle, missing features, design limits and the price for smaller companies. Its reviewers praise its customer support above everything else, and most of those reviews were written in 2021 and 2022.
