Popups by OptinMonster – Best WordPress Popup Plugin


Best WordPress Popup Plugin

Did you know that over 70% of website visitors who leave your website will never return? Why? Because most people find your blog, read, and leave (that’s just a natural pattern).

Wouldn’t it be nice if you can convert some of those people to subscribe to your blog?

That’s where OptinMonster can help. The OptinMonster WordPress popup plugin helps you grow your email list and get more subscribers with popups and other types of high converting optin forms.

OptinMonster App
OptinMonster is a standalone application that integrates with all website platforms including as a WordPress plugin. You must have an OptinMonster account in order to take advantage of our popups and other incredible features. Click here to learn more about OptinMonster.

Powerful Exit Intent® Technology

OptinMonster is among the pioneers of exit intent popup technology. It helps you track user’s mouse behavior and prompt them with a targeted popup message at the precise moment they are about to leave.

Our WordPress exit popups allow you to re-engage the visitor and encourage them to subscribe to your email list. Exit intent is proven to increase conversions.

We used it on our site, WPBeginner, and increased conversions by over 600%.

But don’t just take our word. See what one of the experts are saying:

In only 7 months, we added more than 95,000 names to our email list using OptinMonster’s Exit Intent™ technology. We strongly recommend it!

Advanced Page Level Targeting and Behavior Personalization

Our WordPress popup plugin integrates with our powerful targeting and segmentation engine so you can show your perfect offer to the right people at the exact right time to maximize your website conversions.

OptinMonster’s page level targeting module allows you to display unique offers and campaigns based on visitor’s location and interaction on your website.

This allows you to segment your email list and group your subscribers based on their interest and interaction with your website. Segmentation allows you to send relevant emails to your subscribers which results in higher open rates, higher click through rate, increased sales, greater revenue, greater customer retention, and lower unsubscribe rate.

OptinMonster’s easy A/B split testing tool helps you eliminate the guess work and make data-driven decisions on what works best.

You can try different content, headlines, layouts, styles, and opt-in triggers, to see what converts best.

Bought the full subscription in Nov 18 and have been using it just fine up until a few week ago. We recently upgraded our site, a brand new installation and when we re-downloaded the plugin, we noticed the switch to turn of the Optinmonster branding icon was disabled. after numerous attempts with their email only support (weak) I requested a refund for the balance of the term. I already spent 150, and I would have needed to up it another 10$ per month. Their tech support claims its been that way since we purchased the plan, but, we would NOT have used it with the 3rd party branding, so they are lying to cover up the price bump.

The support techs were a huge help in getting our new campaign up and running. We've already experienced a 47% increase in our daily optins. A highly effective plugin. Excellent support. Recommended with confidence.
