As Hunter Boyle says, popups are like Just Bieber: “You either find them good or evil but now, of late, one notes their presence almost anywhere – as they still attract high numbers.” Okay, it’s safe to say – popups are effective. .. really, really, really effective. I have not witnessed any particular case where optin popups negatively impacted the site’s conversion rate.

Again, I remember several times when pop-ups helped revolutionize CRO by as much as 300 % in specific cases. If you doubt it, you don’t have to believe me; all these points are well-established facts. All that is required is installing one of the best popup plugins for WordPress. These are fast and convenient, and some are available at no cost.

1. OptinAble

OptinAble was one of the pioneers who used free optin popups for marketing, or better said, for lead generation. They dominated the market a few years ago, and even their popup plugin, which I am using today, is one of its best.

Exit-Intent is the flagship selling point that OptinAble offers to users through its software, it is designed to detect when users are likely to leave your page, and it alerts you to send in the optin popup at the best moment.

2. SumoMe ListBuilder

The main reason I began using the SumoMe List Builder app was the free version, which hardly has anything complicated. It is one of those plugins that does not require the kind of help and assistance as other complicated ones; it’s simple and easy to install. In five minutes, you have a simple, subtle opt-in popup based on the abovementioned images on your website.

It can automatically collect emails, and the position of this widget and the frequency of its appearance on your website can be customized. Go premium, and the popup turns into a versatile object with many templates and methods for data gathering.

3. Ninja Popups

Ninja Popups is undoubtedly one of the best top-rated ever sold in CodeCanyon and with good cause. This plugin enables you to create a range of popups with different purposes, be it for getting subscribers’ emails, sharing a video, or sharing on social networks. This offers more creativity than you’ve seen regarding how flexible it is for a twenty-dollar investment.

4. PopUp Domination

Another very good service for pop-ups and other similar opt-in techniques is PopUp Domination which costs mid-range and offers you all the features you need in an optin popup. It encompasses A/B testing and many targeting choices, among others; while most templates are rather dated, they are some of the best in performance.

5. Dreamgrow Scroll Triggered Box

This good, free window plugin allows you to add at least a basic popup to your site. It provides one layout with all the different styles of colors. The Dreamgrow Scroll Triggered Box is one of the most interesting plugins as it does only one work but works perfectly.

6. Icegram

In detail above, Popup is a free plugin that Icegram provides, together with several other marketing-related features. It has quite some interesting features that could be found on some of the best free wallpaper apps, and it could have ranked higher if it had been easier to navigate. If you are of the ‘tape-gaffer’ web designing lot, then Icegram is one of the ways you can introduce some premium aspects and fees.

7. Pippity

Pippity is for everyone who does not want the level of customization found in Ninja Popups but wants something more than a one-feature show like PopupX. It claims to provide one of the simplest interfaces to ‘hack’ into WordPress. While this feature reduces its rank on our list, this plugin is a handy tool for those who do not want to waste time on complex setups.

8. YITH Newsletter Popup

Moving to the full-screen popup, which appears as a floating bar at the bottom when the page loads, this is another simple plugin that only does one thing: to make a full-screen popup. In fact, the spacing and style only appear optimal when one has plenty to say; nonetheless, if you desire a massively boisterous popup template, you shall find none better than this one.
