8 Best WordPress Popup Plugins 2021 (Free & Premium)

Email marketing is the most effective way to build an audience and to promote businesses. In fact, building an email list is one of the best investments you can make.

According to a report, every $1 spent on email marketing brings an average return of $42. That’s a better return on investment than the ROI from all social media platforms combined.

Setting up email optin forms and popup messages are the easiest ways to grow your email list. As well as to convert your website visitors into leads and potential customers.

This is where WordPress popup plugins come to help.

What Is a Popup Plugin?

WordPress popup plugins allow you to easily integrate email marketing services such as MailChimp with your website and to collect the emails of your website visitors. Every email collected from a popup plugin form gets stored directly on your email marketing service automatically.

The main purpose of a popup plugin is to setup popup messages on your website. Most popup plugins come with an editor where you can design your own messages. And setup how the popup messages are shown to visitors. You can choose to show a popup message when a user scrolls down on a page or after a short delay.

This whole process of creating popups and integrating email marketing services is very easy as well.

Main Features to Look for in a Popup Plugin

Before you start looking for a WordPress popup plugin, remember to look for these features and functions.

Compatability with Themes and Plugins

When choosing a popup plugin or any WordPress plugin, the first thing you should do is make sure it’s compatible with your theme and other plugins already installed on your website.

Some plugins often have conflicts with theme functions and third-party plugins. So before you buy and install a plugin, make sure to read the plugin description thoroughly to make sure it’s compatible with all your plugins and themes.

Integration with Email Marketing Services

There are dozens of email marketing services out there. MailChimp, AWeber, Constant Contact, CampaignMonitor, just to name a few. Whichever platform you’re using, check to ensure the popup plugin supports integration with your preferred email marketing service.

Exit-Intent Technology

Have you ever noticed how some websites show a popup message just when you’re about to leave the website or close the tab? Well, that’s done with the help of exit-intent technology.

This technology detects when a visitor is about to leave and shows a popup message to grab their email before they leave. This technology is usually only available with premium popup plugins.

Popup Designer

Designing popup messages to reflect your branding and to blend in with your website design is important to create a seamless user experience. Most popup plugins include a popup builder or an editor that lets you design your own popup forms and messages using a drag and drop interface.

Now that you know what to look for, try checking out some of the popup plugins below to get started.
