These advanced popup triggers are highly effective in growing your email list, reducing cart abandonment, and saving you moeny on PPC advertising and retargeting ads.

Cole Joseph, Owner of Cole’s Classroom See Case Study Popup A/B Testing, Email Marketing Integrations, and Popup Analytics Unlike other WordPress lead generation plugins, OptinMonster comes with reliable A/B split testing and accurate analytics without slowing down your site. Most of them use wp-ajax to setup analytics. This slows down your site and also results in unreliable analytics due to cache plugin settings. Similarly, A/B testing in a most WordPress popup plugins is broken because caching plugins can skew the data. We fixed both these issues with our superior infrastructure, so you can have reliable A/B testing for popups, accurate conversion analytics, and seamless email marketing / CRM integrations for your marketing (bonus: lead storage & lead backup are included, too).
