4.5 of 5 Stars

#1. Thrive Leads

Thrive Leads

Thrive Leads is a feature-heavy list building plugin from the team at Thrive Themes. It is among the highest recommended tools for lead generation. The plugin offers everything you need to build and grow a mailing list from the traffic you drive to your WordPress website.

You are given the ability to create any type of opt-in form you'd like. Not a lot of tools provide this, but Thrive Leads is one of them that gives you lightbox popovers, scroll boxes, in-content forms, and more. You will even have 2-step popovers.

One of the best things about Thrive Leads is the amount of quality opt-in form templates it gives you. For every type of form you have access to 100+ templates that are designed for maximum conversions.

You will also have access to Thrive's front-end WordPress editor—Thrive Architect. It is technically a standalone plugin, but you are able to use this very easy-to-use drag and drop tool to edit your forms.

Thrive Leads Drag and Drop

Thrive Leads offers much more high-end features.

You've got the analytics and reporting, where it shows you how your conversion rates are doing.

You've got the a/b testing, where you can split test your opt-in forms against each other.

You've got the asset delivery, where you can send downloadable content and opt-in incentives straight to your subscribers' inboxes.

You've got the Smart Links feature, where you can customize any URL on your site and send it to your subscribers so they won't have to see you opt-in forms again.

There is more we could talk about here. But we'll save that for a proper Thrive Leads review. 🙂

Thrive Leads Pros and Cons


  • Build any type of opt-in form you'd like. Including 2-step popovers.
  • Design your forms with Thrive Architect, a front-end drag and drop editor that is easy to learn.
  • Access to hundreds of opt-in form templates.
  • Integrates with all or most of the email marketing tools in the space (ex: Mailchimp).
  • Advanced trigger options - exit intent, page load, number of seconds, scroll percentage.
  • Ability to automatically send downloadable assets (ex: checklists, ebooks) straight to your subscriber's inbox after they signup.
  • Ability to display or not display any of your forms anywhere on your WordPress website.
  • Ability to perform A/B split tests against two different types of forms or 2 of the same.
  • Everything is tracked - clicks, impressions, and conversions.
  • Will not break the bank. Unlike some on this list, you can get Thrive Leads for a one-time fee.


  • Support is limited to one year. If you need further assistance you will need to pay for it.
  • Does not come with broadcasting, apart from the asset delivery feature. You will need to find this service elsewhere, we like ConvertKit. 🙂

#2. OptinMonster


OptinMonster is very similar to Thrive Leads. They offer just about the same product with the same set of high-end features.

One of the major differences, however, is OptinMonster is not a WordPress plugin anymore. It started out as one, but it was recently turned into a cloud based web app. Meaning everything is done outside your WordPress blog.

This is great for two reasons: 1) if you have multiple sites you can run everything in one place, and 2) you will have one less plugin installed on your website, making it better for performance reasons.

The best thing we like about OptinMonster is how smooth their interface face. Instead of having to click and load multiple pages OptinMonster has everything set in five tabs. This makes it super easy to create your opt-in forms. And you get a pretty great drag and drop editor too.

As for opt-in forms, you'll have access to popovers, slide-ins, fullscreen welcome mats, floating ribbon bars, and in-content boxes. That's basically every type of opt-in form you'd need. And they all have dozens of high-quality templates to choose from.

You will also have the ability to create 2-step opt-in forms using their MonsterLinks feature. This allows you to turn any text or image into a clickable link that triggers a popover.

The powerful lead generation tool comes with a ton of high-end features. The advanced display rules lets you display any form on any page you want. The trigger option lets you trigger your forms based on the amount of time, the scrolling percentage, or even when it detects exit intent or inactivity.

There is a truckload of more features we could talk about. But we'll leave that for a proper OptinMonster review. 🙂 For now, you can find more details below.

OptinMonster Pros and Cons


  • Great interface. Makes the process of creating opt-in forms a walk in the park.
  • Comes with all the essential types of opt-in forms. All with dozens of great templates.
  • MonsterLinks gives you the ability to create 2-step opt-in forms.
  • Advanced display rules gives you the ability to display or not display your forms anywhere.
  • Ability to trigger forms based on exit intent, time on page, scroll percentage, or even inactivity.
  • Ability to perform advanced A/B split tests.
  • Integrates with all the popular email solutions.
  • Tracks everything - clicks, impressions, and conversions.
  • Supports content locking, geo-targeting, adblock detection, and more.


  • Even though you can get access for $9 a month (billed annually), this plan is very limited. You only get popovers.
  • To have access to everything OptinMonster offers, you must opt for their Growth plan, which costs nearly $600 a year.
  • May run into problems if you run multiple sites. Their top plan only supports 5 sites. 

#3. Sumo


Sumo is one of the most popular list building tools out there. The best thing about Sumo is it's free to use. And you'll get access to most of its high-end features.

One of the great things about this tool is everything is done on Sumo's servers. But to connect it with your site, you will need to install the Sumo plugin.

Another thing you will probably like is you could nurture your mailing list right from your Sumo dashboard.

Sumo will keep track of every person who signs up.

And you will be able to send emails anytime you'd like.

To build your list, Sumo offers all the best types of optin forms. You've got the popup, the scroll box, the inline (in content), the welcome mat, the smart bar, and even the two-step popover (triggers when link is clicked).

We'll take a much deeper dive into the tool in a Sumo review. But for now, you should take a look at these:

Sumo Pros and Cons


  • Simple form editor that is fairly easy to use.
  • Access to all the popular opt-in forms, including the 2-step.
  • Access to dozens of decent opt-in form templates.
  • Access to advanced analytics and proper A/B testing.
  • Access to three extras, including share buttons.
  • Ability to send emails to your mailing list.
  • Integrates with all the major email providers.
  • Comes with a free version.


  • Design features and elements feel limited.
  • While it comes with a free version, it's hard to imagine being successful with it, as it is very limiting.

#4. LeadPages


LeadPages is a web-based lead generation tool similar to OptinMonster, in that everything is done outside your WordPress admin dashboard. LeadPages, however, is very different from the others on this list.

At its core, LeadPages is a landing page builder. It's one of the best in the market. Easy to use, a great selection of quality templates, and 100% customizable.

There are also two tools for opt-in forms—pop-ups and alert bars (top/bottom). Both comes with quality templates and the easy to use drag and drop builder.

We could go on and on about LeadPages. But we'll leave that for a proper Leadpages review. 🙂

LeadPages Pros and Cons


  • Ability to create high converting landing pages.
  • Ability to create full on websites from the LeadPages platform.
  • A fairly easy to use drag and drop builder.
  • Comes with A/B testing and analytics and reporting.
  • Integrates with all the popular email marketing platforms.
  • Offers a 14-day free trial.


  • Does not support regular opt-in forms, aside from pop-up boxes and top/bottom bars.
  • Does not provide templates for the opt-in forms. You're left with a basic layout.
  • All in all, the opt-in forms need a lot of work.

#5. MailMunch


Like all the other six plugins on this list, MailMunch could be number one. It offers everything you need to convert your website visitors into email subscribers. And more.

There's the optin forms:

It may not provide a larger selection as others on this list, but these five types will surely do the trick.

The popover (popup) is one of the highest converting optin forms out there. Especially when it's used with exit-intent. And MailMunch offers this feature.

The embedded form can be used anywhere throughout your website. One way to use it with content upgrades.

For example, if you've got a blog post about the top recipes for lunch, you can create a PDF where you have all the recipes in a tidy checklist. You can then embed your form at the beginning or end of your post where your readers would see it.

And for the other three...

The topbar to convert visitors in the first few seconds, the scrollbox to convert people toward the end of their visit, and the sidebar for everyone else.

Aside from the forms, MailMunch offers another way to generate leads. Landing pages.

There are 21 templates to choose from. But only two are available in the free version - one of which is very basic.

You will also be given the ability to nurture your leads with MailMunch's broadcast and autoresponder features.

Broadcasts will let you send emails straight to your subscribers' inboxes.

Autoresponders will let you send emails the second a person subscribes to your list. This can be a welcome email or a delivery system for your incentives and content upgrades.

Now, MailMunch also offers a bunch of other cool features. But we'll save the rest for a proper MailMunch review. 🙂

MailMunch Pros and Cons


  • Comes with a good drag and drop editor that is easy to use.
  • Supports 2-step technology.
  • Access to the essential types of opt-in forms, each with around a dozen quality templates.
  • Access to landing pages for even more lead generation opportunities.
  • Advanced display rules and trigger options. On par.
  • Advanced analytics and A/B split testing.
  • Ingrates with most of the popular email marketing platforms.
  • Everything is done on the MailMunch platform.
  • Mobile optimized.
  • Affordable. Comes with a free version.


  • Cannot redirect your subscribers to Thank You pages after opting in.
  • Does not support screen filling opt-in forms.

#6. ConvertPro

Convert Pro

Convert Pro was nowhere near our radar prior to the research for this post. But, we're glad we found it.

Why are they on this list?

First off, Convert Pro offers a wide selection of opt-in forms, each with their own templates.

The triggering options are some of the best we've ever seen. There are a few of them to choose from, but they're also very easy to configure.

The Modal Popup (lightbox popover), for instance, can be set to trigger only when visitors are about to leave your website.

Only a couple forms offer the exit intent. But there are other triggers, too. There's one where you can trigger at an X amount of seconds. There's another where you can trigger when the visitor shows inactivity for 60 seconds. And there are two more where one triggers after scrolling down a percentage of the page and the other at the end of a blog post.

Can you A/B test these forms, you ask? Yes.

However, it's not as pretty as others on this list. First, you will need to hook up your Google Analytics account with the tool so everything can be tracked.

But the test creation process is very simple. And you could have the tool automatically pick a winner after an X amount of time.

We'll publish a full ConvertPro review in the near future. You can check out the pros and cons here for now:

ConvertPro Pros and Cons


  • A very nice drag and drop builder that is easy to use and learn.
  • Comes with most of the popular types of forms.
  • Integrates with the popular email solutions.
  • Display or not display forms on any page.
  • Trigger options include exit intent, time on page, and scroll percentage.
  • Supports adblock detection.


  • After comparing its pricing with the others, it's not the worst but could be a lot better.
  • Some templates are pretty basic.
  • Does not support email broadcasting or autoresponders.

#7. Bloom

Bloom Email Optin Plugin

Bloom is the email opt-in plugin by Elegant Themes, the geniuses behind one of the most popular WordPress themes ever—Divi.

Bloom offers nearly everything the top tools offer. Such as a wide selection of form templates, A/B testing and analytics, ability to choose where your forms are displayed, and more.

With that said, there are reasons this plugin isn't in our top 5.

For one, it does not support the front-end drag and drop builder. While their editor provides a preview button and decent customization options, we believe that it isn't as powerful as Thrive Leads or OptinMonster, for example.

Another reason is it does not support exit-intent technology, which has become an essential tactic in boosting conversions.

On top of that, you cannot purchase Bloom on its own. Which may be a blessing in disguise. Elegant Themes offers all their products in their membership—which includes high-quality themes and one of the best social sharing plugins.

There are a ton of great things about Bloom also. We'll go more in-depth in our Bloom review. 🙂

Bloom Pros and Cons


  • Supports the popover, inline box, widget, slide in, and content locking.
  • Supports the 2-step trigger option.
  • Supports A/B testing and analytics and reporting.
  • Comes with 100+ opt-in form templates.
  • Integrates with all the popular email marketing platforms.


  • Does not support some form types - top/bottom bar, scroll welcome mat, screen filler.
  • Does not support the front-end drag and drop builder.
  • Does not support exit-intent.
  • Cannot buy the plugin separately.

#8. MailOptin


MailOptin is one of those email plugins that could end up in our top 3 very soon. The right features are there. We are looking forward to seeing what the plugin becomes in the future.

It's a freemium type of plugin where you could install it straight from your WordPress dashboard via the plugins page. But like with all freemium tools, it is very limited.

One of the great things about this opt-in forms plugin is the lead nurturing feature. If you opt for the paid version you will gain access to email broadcasts where you could send newsletters straight out of WordPress.

And to actually grow your mailing list, you will have access to the essential types of opt-in forms—popovers, slide-ins, widgets, etc.

Do you want more details? Don't worry. We're going in-depth with this one in a proper MailOptin review. 

MailOptin Pros and Cons


  • Create nice opt-in forms using the WordPress customizer.
  • Increase conversions with split tests, analytics, and reporting.
  • Display your forms on any post or page.
  • Ability to choose your triggers - exit intent, etc.
  • Integrates with the major email marketing platforms.


  • Needs its own drag and drop editor and more opt-on templates.
  • Missing the screen filler forms like the welcome/scroll mat.
  • Annual premium pricing may be a little high, however, considering it offers more than just opt-in forms, perhaps it could be worth the dough.

#9. WP Subscribe Pro

WP Subscribe Pro

WP Subscribe Pro is not like the top plugins. It''s part of the MyThemeShop suite. And it's a smaller mailing list plugin. In that it does not offer the selection of opt-in form types nor templates.

It also does not provide a drag and drop builder. But its form builder is fairly easy to use.

All in all, this is a simple list building plugin. With its cheap pricing, it's a perfect starter tool for anyone who is just starting their blog. You would get access to the pop-up box and the widget.

If you're interested in more information, you can look out our WP Subscribe Pro review.

WP Subscribe Pro Pros and Cons


  • Lightweight and responsive.
  • Decent display and trigger settings.
  • Integrates with some of the most popular email marketing providers.
  • Will not break the bank. Very affordable.


  • It's a beginner plugin that only supports pop-up and widget forms.
  • No drag and drop builder.
  • Basic design options.

#10. Optin Feature Box by PlugMatter

Plugmatter's Optin Feature Box is a different plugin. Very unique to the others on this list.

This only gives you one type of opt-in form. The Feature Box.

This opt-in type is located at the top of a webpage—right below the navigation area and above the page's title/headline.

Plugmatter offers 10 templates for your feature box. Each are 100% customizable.

You can give it a try for free on their website. The design editor is simple to use.

If you would like more information we'll go more in-depth in our Plugmatter Optin Feature Box review.

PlugMatter Feature Box Pros and Cons


  • Create a high converting feature box with ease.
  • Lightweight and responsive.
  • A/B testing, analytics, and reporting.
  • Display your feature box on any post or page.
  • Integrates with many email marketing platforms.
  • Affordable. One time fee.


  • If you want more than a feature box you'll need a separate plugin/tool.
  • If you're picky 10 templates may not be enough.

Best WordPress List Building Plugin For ME?

We gave you ten list building tools to choose from. How the heck are you supposed to pick one that won't waste your time (and money)?

If you want nothing but quality, we'd have to recommend Thrive Leads. There's a reason why it holds the top spot. We've used it for years.

But if you cannot afford a premium opt-in plugin right now, perhaps you should give MailMunch a try.
