OptinMonster - 2026 Pricing, Features, Reviews & Alternatives

OptinMonster is a cloud-based solution for lead generation and marketing automation which allows users to create and A/B test a range of custom opt-in forms.

With OptinMonster, users can build a range of form types, including slide-ins, floating bars, inline forms, scroll boxes, lightbox popups, slide-ins, and more. The drag-and-drop form builder allows users to customize form branding, including messages, images, and colors, without requiring any coding. Built-in page-level targeting enables the display of unique campaigns or offers based on the location and behavior of visitors, allowing users to segment their email list based on subscribers’ interests and website interactions. Different form variations can be A/B tested to identify the version with the highest conversion rate, with users able to change the form headline, content, style, layout, and opt-in trigger. OptinMonster automatically replicates the existing opt-in form being tested for users to make changes to, then randomly serves up each variation to visitors and tracks impressions, conversions, and landing pages for each option.

OptinMonster also includes Exit-Intent® Technology, which automatically tracks visitor behavior, identifies when they are about to navigate away from the site, and serves up targeted campaigns as they are about to leave. The system is designed to reduce cart abandonment and increase conversions. Campaigns can include invitations to chat with support agents, special offers or discounts, incentivised email list signups, and more.
