OptiMonk

OptiMonk is a popup and banner builder that specializes in exit-intent technology, which triggers when a visitor's mouse leaves the window. Behavioral targeting lets you show different popups to repeat visitors, mobile users, or people from specific referrers, all designed to capture emails.

E-commerce sites and publishers use it to recover abandoning traffic, reduce bounce rates, and grow their lists. It works as a plugin on WordPress or integrates via a code snippet on other platforms.
