In our Email Lab experiment, Omnisend exit-intent popups resulted in a 19.03% conversion rate (and helped Organic Aromas boost signups by 150%). Almost one-fifth of all new subscribers converted into customers with a single popup!
Not too shabby at all.
The exit-intent dialog box gives you an additional chance to re-engage with a visitor when he/she is about to leave your website. You might stop them from exiting by offering a signup deal.
