wphacks email list building plugins

If you don’t already have an email list for your website, you should probably stop everything you’re doing and start building one right now.

Your mailing list – the list of people who have signed up to receive emails from you – is potentially the most valuable asset in your marketing arsenal, and can help you to increase site traffic, build better relationships and trust with your audience, and ultimately make more money.

Email lists are so powerful because they offer an amazing conversion rate compared to other types of online marketing – in fact, email is 40x more effective than social media for acquiring new customers.

Your list is also totally owned by you and under your control.

Google changes its algorithms and sends you back to page 10 of the listings? No worries.

Facebook decides to start charging for business pages? Who needs Facebook anyway?

Ok so you’re convinced – you need an email list. But how on earth do you get started at building one?

Fear not, as WordPress site owners are spoiled for choice in terms of list building plugins that will do all the hard work for you so you can sit back and let the sign-ups start flying in!

Best Mailing List Plugins to Choose From for Powerful List Building

All you need to start building an email list is a simple form on your site to capture a visitor’s name and email.

Plugins make it easy to add this form to your site without any coding required and all the data you collect will be added to your WordPress database for easy export or integration with mailing software.

Effective list building plugins also offer extra features to help improve your conversions such as:

  • Pop-ups, slide-ins, and other eye-catching ways to display your sign-up form
  • Functionality to offer opt-in incentives such as a free e-book
  • Reporting so you can see how well your forms are performing

Looking for a plugin that offers all of this and more? Read on for a summary of some of the best list building plugins for WordPress:

01. Thrive Leads

Thrive Leads

Thrive Leads is considered by many to be the gold standard of list building plugins and it offers pretty much any feature you could possibly want, along with unlimited customization options.

This is a premium plugin but it’s actually great value for money considering all the functionality that you get, and it’s cheaper than several of the other premium options.

One of the great things about this plugin is that it’s designed specifically for WordPress users by the team behind Thrive Themes, so you know it’s a quality plugin that’s not going to slow your site down like some other generic solutions that aren’t built for WordPress in particular.

Price: $90 / quarterly or $228 / yearly

02. ConvertBox


ConvertBox is just like every other marketing tool in the market. It lets you collect leads by integrating with some of the best email marketing service providers around, segment your funnels, create lead capture forms, and even A/B test variations to see what’s working (and what’s not).

That said, this WordPress mailing list plugin prides itself in giving website owners a way to personalize every experience site visitors have while on your site. In other words, you don’t just display a random popup optin form whenever someone lands on your site. Instead, you deliver the right kind of message to people based on their interests.

ConvertBox comes with 4 built-in notification templates that include simple corner callouts, notification bars, modal window popups, and full page takeovers. And with a powerful, yet user-friendly drag and drop editor, you can easily create whatever kind of marketing element you need to build a bigger email list and grow your business.

Features included in ConvertBox include:

  • Real-time data tracking and analysis
  • Segmenting and tagging capability
  • Intelligent targeting based on CRM data, sales, referrers, and more
  • Dynamic text replacement for delivering personalized messages
  • Countdown timers that integrate seamlessly with all offers
  • Specialized mobile editor for on the go changes
  • Fast cloning of elements or entire steps
  • And much more…soon

This new guy on the block is not quite available yet. In fact, the team behind ConvertBox is working hard to add more powerful features to the plugin before making it available to all. However, if you’re interested, you can request early access now and see what all the hype is about. For doing so, you’ll even lock in a special lifetime price.

Price: Will be $99/month or $1,188/year…unless you unlock the early bird special, which right now is going for a one-time payment of $395. This license will be good for up to 10 websites and come with 250K views/month.

03. Optin Forms

Optin Forms

Optin Forms is a free plugin developed by the team at FancyThemes and is a simple solution for creating opt-in forms on your website without any coding knowledge or fuss.

It comes with five customizable form designs and works with 7 of the most common email marketing solutions including AWeber and Mailchimp.

This plugin doesn’t have the fancy templates and advanced features of many of the other list-building software solutions. However if you’re after something simple and free, and you’re using one of the supported marketing platforms, it does the job.

Price: FREE

04. OptinMonster


OptinMonster is designed to increase the conversion rate of your website – converting visitors into subscribers, growing your email list, increasing page views, and getting more sales.

This plugin comes with over 65 pre-designed mobile-friendly form templates that are ready for you to customize as you wish. An advanced targeting engine also allows you to show personalized messages based on user behavior.

Some of the features included with OptinMonster include:

  • Drag and drop form builder
  • Automated actions and personalized messages based on user behavior
  • A/B split testing
  • OnSite retargeting – customizing promotions for returning users
  • Integration with major eCommerce platforms

OptinMonster is particularly powerful in its targeting based on location, device, referrer, page, cookie, and more. It’s a good choice for eCommerce sites running segmented marketing campaigns.

One other thing to note is that OptinMonster is cloud-based rather than being a traditional WordPress plugin. This can be useful if you want to use it on several sites as everything can be managed in one central location. You can use it on any website – not just WordPress sites

Price: $9 – $29 a month depending on the features required and the number of sites you want to use it on.

05. OptimizePress


OptimizePress is a landing page builder rather than an opt-in form builder. It provides mobile-ready templates for creating landing pages, sales pages, and product launch funnels.

Sometimes the optimal way of building your list is by using targeted landing pages rather than a form integrated with the rest of your content. Of course you don’t have to choose between the two – often a combined approach is the best option.

Most list building plugins don’t have the option to build whole landing pages so OptimizePress is definitely worth a look if that’s what you’re trying to do. It’s really easy to use with a drag and drop builder and you can choose to either customize one of the pre-built templates or start from scratch with your own design.

As well as the all-important opt-in form, there are over 40 custom elements to choose from when you’re building your page such as testimonial blocks, progress bars, and video players.

Another feature that will come in handy for some users is the plugin’s capability to create secure membership portals – you can create a member’s only area of your site as an incentive to sign up for your mailing list without the need for any extra software.

Price: $97 for use on up to 3 sites.

06. Bloom


Bloom is one of the plugins offered with Elegant Themes membership, which means if you’re already an Elegant Themes member, you can use it on any of your sites for no additional charge.

The pop-ups and fly-ins can be triggered by various user actions including time spent on page, reaching the bottom of the post, after scrolling, or after purchasing. However it’s notably missing the “exit intent” trigger that’s a feature of some other plugins.

Just like the themes that Elegant Themes is most famous for, Bloom is beautifully designed and comes with over 100 professional templates that you’re free to customize for your own purposes.

💯 You can learn more about Elegant Themes in our review here.

Other features include:

  • A/B split testing
  • Integration with an unlimited number of mailing list accounts
  • Conversion and list statistics
  • Targeted display settings.

Bloom strikes a nice balance between offering a flexibility and customization without being bloated and providing you with lots of extra features you probably won’t use.

Price: Included with Elegant Themes membership ($89 per year)

07. Leadpages


Like OptimizePress, Leadpages is a landing page builder that you can use to create launch pages, opt-in campaigns, and more.

It comes with over 160 beautifully designed templates ready for editing, that are optimized for conversion. In fact you can even choose templates based on their conversion rate to give yourself the best chance at getting new sign-ups to your mailing list.

Leadpages also comes with a Facebook ad builder, which will come in handy for those looking to build an audience through social channels.

Sumo provides a whole suite of tools designed to grow your website’s traffic and encourage people to sign up to your mailing list.

There are a few tools that come in the package that you’ll be most interested in if you want to build your list:

  • List Builder makes it easy for you to create a lightbox pop-up to capture emails, integrated with all the main email campaign software

09. Ninja Popups

Ninja Popups

Ninja Popups integrates with all the popular mailing list software and makes it easy for you to create pop-ups that are specifically designed to convert.

A drag and drop editor simplifies pop-up creation and there is a library of over 70 pre-designed themes to choose from.

The pop-up can be triggered by exit intent, scrolling, or after a set time of inactivity. You can also target different pop-ups for different pages.

Other features include:

  • Opt-in locker
  • Social locker
  • A/B testing
  • Anti pop-up-blocker system
  • Over 70 animation effects.

Ninja pop-ups is very reasonably priced and a lot cheaper than many of the other list-building plugins. It doesn’t offer as much customization and as many features as some other solutions, but if you just want to create pop-ups, it’s a great value option.

For a small additional fee you can buy add-on packs including the Opt-in Bars pack to turn your pop-up into a bar ($12), the Widget Extra add-on to integrate your designed pop-ups into content as a widget ($8), and an extra theme pack, which includes ten new theme designs ($9).

Price: $25

Choosing the Best WordPress Mailing List Plugin

All of these plugins work well and will make the task of building your list much easier and faster. If you’re still not sure which one to pick, take a moment to think exactly what you want from a plugin.

If you just want to add a simple subscriber form in a pop-up and you’d rather not spend any money, one of the free options such as Optin Forms will do the job.

Thrive Leads and ConvertBox are both premium solutions with lots of features. If you’re managing lots of sites, Convertbox’s cloud-based dashboard will make your job easier, but otherwise Thrive Leads works out better value for money with a one-off payment.

If you want to build landing pages rather than just a couple of pop-ups, you may want to look at Thrive Architect or Leadpages.

For Elegant Themes members, no need to buy an extra plugin as Bloom does the job beautifully. If you’re not already a member you might want to consider it to get access to the themes and other plugins.

  1. Why aren’t their solutions for the stock WordPress Jetpack Email subscription forms? I have been using them and it’s completely free. The only lack is the support for Jetpack Email subscription forms or its shortcode.
    It sends an email to every email subscriber automatically whenever a new post is published.
