I was once a disbeliever myself. I didn't like popups at all. But we doubled our email signups, so the results speak for themselves, it just works. OptinMonster makes it super easy and is well worth the money.

Exit intent popups have doubled my email opt-in rate. When done right, you can see an instant 12% lift on driving sales. I highly recommend that you use OptinMonster for growing your email list and sales.

Ever since we installed OptinMonster we have seen a 241% increase in newsletter signups on Search Engine Journal. Not only have we had more signups, but the popup itself is very easy to customize and comes across as an unobtrusive way to transparently build a marketing list.
