OptinMonster specializes in converting website visitors into email subscribers and leads using pop-ups, slide-ins, floating bars, and other on-site campaign types. Syed Balkhi and Thomas Griffin launched it in 2013 as a WordPress plugin, and it has since evolved into a standalone SaaS platform that works with any website.
The tool’s strength is its targeting and trigger system. You can show different offers based on referral source, geographic location, device type, pages visited, time on site, and more. Exit-intent technology detects when a user is about to leave the page and displays a targeted campaign — a technique that’s become standard practice in e-commerce and lead generation.
OptinMonster’s page-level targeting lets you customize campaigns for specific URLs, categories, or content types. A visitor reading a blog post about email marketing sees a different opt-in offer than someone browsing your pricing page. This level of targeting significantly outperforms generic site-wide pop-ups.
The drag-and-drop builder includes a library of pre-built templates for lightbox pop-ups, fullscreen welcome mats, slide-in scroll boxes, gamified spin-to-win wheels, and inline forms. A/B testing lets you compare different headlines, offers, and designs.
OptinMonster claims to serve over 1.2 million websites. It’s part of the Awesome Motive portfolio alongside WPForms, MonsterInsights, and other popular WordPress products. Pricing starts at $9/month for the Basic plan (billed annually), making it accessible for small sites. The Pro and Growth plans unlock advanced targeting, behavior automation, and more campaign types. The tool integrates with every major email marketing platform, CRM, and e-commerce platform.
