7 Best Email List Building Plugins for WordPress


Are you looking for a proven way to boost site engagement, conversions, and sales?

If you are, look no further than your email list.

An email list can have a profound effect on your website, whether you run a blog, online business, or recently launched an eCommerce shop. In fact, an email list full of the addresses of people that have shown interest in your brand offers you the perfect way to stay in touch with them long after they’ve left your site.

Of course, you’ll need to collect some email addresses before you can start sending out your email campaigns.

The good news is, however, that cultivating an email list may be easier than you think. All you need is the right email list building plugin to help your visitors subscribe to your list quickly and effortlessly.

Today we’re going to take a look at the top WordPress email list building plugins in the market. But first, let’s dive into why email is the top marketing channel.

Why Stick with Email Marketing?

Many people will tell you that email is dead and not worth the effort. What’s more, they’ll try to convince you that social media and blog content are the best ways to improve traffic numbers, increase conversions, and keep site engagement at an all-time high.

Of course, building a strong social media presence and publishing valuable content are always going to be important. But when you take a look at the benefits that email marketing provides, there’s really no excuse not to build a bigger email list.


So, now that you know why you should invest in an email marketing strategy, let’s take a look at some of the best email list building plugins for WordPress.

Best Email List Building Plugins for WordPress

1. Thrive Leads

Thrive Leads might just be the best WordPress list building plugins out there. It comes with every feature you could possibly need to grow an email list with highly qualified subscribers, and offers site owners plenty of design and customization options for seamless branding.

You can choose from a variety of opt-in form types such as a lightbox popup, widget opt-in, in-content form, slide-ins, content lock, and even a screen filler.

From there, you can target your site visitors in a way that will boost conversions. For instance, display specific opt-in forms based on category or tag or on certain posts or pages. More so, reveal certain opt-in boxes to return visitors and new visitors so they get the offers they want.

  • 20+ opt-in box animations
  • Drag-and-drop editor for easy form creation
  • 2-Step Opt-in Forms
  • A/B Testing and detailed analytics

  • 4 trigger actions: exit intent, time delay, scroll, and element clicks

Thrive Leads can be purchased for a one-time payment of $67 for use on a single WordPress site. If you want the best value for your money, however, you might consider signing up for a Thrive Themes Membership($19/month) so you can access all of their themes and plugins on up to 25 websites.

2. OptinMonster


OptinMonster is another full-featured solution that fits right in with our roundup of email list building plugins for WordPress. That said, OptinMonster is not so much as a plugin as it is a web application that works seamlessly with all platforms, not just WordPress.

Check out our real-life Wix examples and stunning Squarespace examples if you’re on the fence about which platform to use.

Use the drag & drop builder to easily create any number of opt-in forms (complete with pre-designed templates) – fullscreen welcome mats, inline forms, floating bars, and even countdown timers – and encourage site visitors to subscribe the minute they arrive on your site.

In addition, define the following types of trigger actions, all based on user behavior: exit intent, 2-step optins (click a link or image), scroll trigger, timed display, campaign schedules, and inactivity.

Which WordPress Email List Plugin is Best For You?

Since every site owner has different needs, we’ve narrowed it down a bit here to help you choose the right fit.

Thrive Leads is widely considered one of the best list building plugins for WordPress users. It gives you all the necessary features, the best value for your money, and comes with regular updates. Moreover, if you’re not sure yet what you want to do with popups or forms for your site, Thrive Leads is best, because it’s so comprehensive.

Bloom is a great deal because you get so much value for your money (they include other plugins and themes in the package in the price). Another advantage Bloom comes with is access to some cutting-edge features such as trigger actions like after commenting and purchasing, which isn’t seen with other list building plugins.

If you’re interested in unique features, OptinMonster could be right for you. For example, you can set up a popup to display based on how someone has interacted with a product or service you’re offering. OptinMonster is also ideal if you have more than one website to manage, or if you’re looking for a lightweight plugin.

If you’re looking for something quick, simple, and easy, download the free version of WP Subscribe. And for those wanting to avoid popup opt-in forms at all costs, Optin Forms is the most affordable, customizable, and popup-free option on the list.

Wrapping Up

Before we leave you to your decision, here’s one word of advice:

Each of these plugins provides you with plenty of options for your popups and/or opt-in forms (no hurting for choice here!). The trick is to experiment with different form types to see which type of opt-in form produces the highest conversion rates for you.

Then, you can stick with what works best and watch your email list grow like it never has before.
