I hate popups, so I was hesitant to try one on my site. But the results from OptinMonster exit-intent popup speak for themselves. I doubled my subscription rate immediately without annoying my users. I haven’t had a single complaint. My only regret is that I didn’t start using OptinMonster sooner. I can only imagine how many subscribers I could have added to my email list! If you have a blog, then I highly recommend you start using OptinMonster. I’ve researched them all, and it’s the best in market.

Don’t take our word for it. See for yourself!

OptinMonster played a huge role in growing my email list from 0 to 11.3k in my blog’s very first year. Before OptinMonster, I was getting just a few email subscribers/day – now I’m adding over 3,000 subscribers to my list every month. It’s also great for custom page-level affiliate offers to drive sales. I can’t recommend it enough.
