Convert Abandoning Visitors into Subscribers

Over 70% of visitors who abandon your website will never return. Our exit-intent technology detects the exact moment a visitor is about to leave your site so you can display a targeted optin form to convert them into subscribers or display an exclusive offer.

Time on Site triggers allows you to instantly show your optin to visitors or display it after they’ve been on your site for a specific time. This strategy is perfect for rewarding visitors who have spent a lot of time on your site.
