10 of the Best List Building Plugins for WordPress In 2015

No matter what niche you are in, one thing you need to focus most on is building an engaging email list. This will not only help you get more targeted traffic, but it will also help you build trust with your audience.

If you want to run a successful business online, building an email list is the way to go.

Email list is the key. An engaging email list of subscribers can easily out-perform the results from social media sites like Facebook or Twitter.

The easiest way to go about this is to make it super easy for your readers to subscribe to your email list. This means adding opt-in forms in key locations of your website including sidebar and below content area. There is a good number of free and premium plugins available in the market, that makes it easy to add opt-in forms on your WordPress powered website.

In this post, I will share some of the best list building plugins that can help you get more email subscribers.

Top Mailing List WordPress Plugins

1. Optin Monster


With a long list of features, OptinMonster tops this list building plugins’ roundup. It is a revolutionary plugin. Name a thing that you could do to create a list and make more people to signup, and OptinMonster can do it for you.

With OptinMonster, you can ask people to join your mailing lists through different ways.

Optin Skin is a powerful list building plugin for WordPress. Optin Skin comes with 18 templates (skins). You can customize those skins or create a new one (requires basic knowledge of HTML and CSS) to match your blog design. There’s a $97 flat fee for unlimited sites license – it includes lifetime updates and support, which is pretty decent for its features. Optin Skin supports split testing, so you can test the theme, and see how it is converting. Also, an impression is only counted if the user reaches or scrolls through the point where your form is visible. You can analyse each skin’s performance through Optin Skin’s settings page.

Thrive Leads is a powerful lead generation tool that comes with a dozen of fantastic features and optin form designs. After OptinMonster, this is my second-best choice for popup plugins.

6. SumoMe

sumome plugin

SumoMe List Builder is a free list builder app from AppSumo. However there are some restrictions. At the time of writing this post, SumoMe only supports MailChimp, Aweber, Campaign Monitor, and Constant Contact. So if you’re using any other service, then you can rule out this plugin.

Sumome has a very premium feel about it. You can create elegant lightbox popups that drive subscribers. You can also set Sumome to show a popup when the users are about to leave your site (exit intent technology). You will find many other premium optin popup plugins that rave about this feature. But Sumome offers it for free and is very easy to setup.

Adding optin form below the header is an incredible way to build your list.

How to Pick the Right Plugin?

If you’re investing in a premium list building plugin, then consider the ones that allow split testing. Because there’s no sure way to know which method works best than testing out different variations.

Thrive Leads is perfect for WordPress site owners, who want value for money. The plugin provides all the useful features including different triggers to test optin forms, well-designed templates, timely optin forms, and content upgrade style forms.

SumoMe for people who want something more than just list building solution. The plugin follows a freemium model and is packed with some great features including that aren’t for list building like social sharing buttons, heatmap solution, anlaytics, among other stuff. I have been using on WPKube for last few weeks and so far it doesn’t seem to be that resource-intensive. Plus they have some unique features like Welcome Mat, that you won’t find in other plugins.

Want a lightweight solution? Go with OptinMonster. Not a plugin technically, as they are now a cloud app, but it still has all the features you need to build a powerful email list. Plus it can work on any type of site (including the ones that aren’t on WordPress).

That’s it for the best list building plugins. If you have any questions about how to install / configure any of these plugins on your site, feel free to drop a line in the comments section below.

  1. Jens P. Berget says

    Hi Devesh,

    I can confirm that optinskin is an awesome plugin. I have been using it for a while and it’s brilliant.

    It was very easy to install and I love the split-testing and the stats that are available.

    Great post.

    • Devesh says

      Hi Jens,

      That’s excellent to hear. Thanks for coming over here and leaving a nice comment.

      Have a fantastic day.

  2. Ann says

    Thank you for the information. I will consider Optinskin and will get if from you if I need it. Good work, Devesh.

  3. Ehsan Ullah says

    I have been searching for something similar plugin for free and I’ve found out many, but Optinskin is Optinskin, Really I have to buy this plugin as soon as possible.

    • Devesh says

      hehe Ehsan. There is no better plugin then OptinSkin, I’ve been using it for last few weeks and getting great results.

      Thanks for stopping by, bud.

  4. Rahul kuntala says

    I’m in the process of building email list for my blog, I’m going at good pace even without using any extra plugins, thanks to MD2..

    But, I should check out this plugin (I heard a lot of buzz about this).. Thanks for the review Dev!

    • Devesh says

      Hey Rahul,

      That’s fantastic to hear. MD2 is a fantastic skin, Alex did excellent job in adding extra (list building) features.

      Thanks so much for coming over here and leaving a nice comment.

  5. OKay Marketing says

    This is a great list Devesh! I’m finally glad to see someone mention WP Subscribe and Optin Forms. Both are great. Sometimes people get a little too over hyped with Ninja and SumoMe… I am actually having great success with WP Subscribe and in my opinion it looks the best out of all of them. Boris, the developer of Optin Forms also released a new premium plugin called Optin Lock which is basically Optin Forms on steroids :) You should take a look. Again, great list and happy new years!

    • Devesh says

      You’re right, those two are great plugins. I have been experimenting with WP Subscribe Pro and really liked the interface. Plus it only costs around $19.

      Thanks for your suggestion – I’ll check it out.

      Happy New Year, Brian.

  6. donna merrill says

    Hey Dev,

    Gosh, I feel like a kid in a candy store! What a great collection and I want them all!

    This is how I feel as I went down each of the ones listed. They are fantastic and from a marketer’s perspective, my mind is spinning.

    This is a keeper and I’ve bookmarked it already so that I can return to review this more carefully and run it by my partner.

    Thanks so much, I didn’t know the many things that these can do.


    • Devesh says

      Ah that’s awesome to hear :). Thanks for the nice comment, Donna.

      Would love to hear which candy plugin you plan to use on your site.

  7. Jake says

    I am tempted to buy optin monster, but with thrive leads just around the corner, I think I will wait a bit and see what they come up with.

    • Devesh says

      Yup, it will be releasing in a few weeks. Definitely worth a wait, considering all the products, Thrive Themes has released in past few months are well coded and easy to use.

      I plan to update the post, once it is released.

      Thanks for the comment, Jake. Enjoy your rest of the weekend.

  8. Adrienne says

    Hey Dev,

    This is a great post and I went in search this past week of a better list building plugin. I actually purchased OptIn Monster but ran into a few issues with it. I emailed support and they are trying to help me out with it so I might not have it up and running by the time I get back to blogging on Monday.

    I checked out a few others like Hybrid Connect but when I put the code on my site the opt-in box didn’t appear. I know I’m not the smartest person with coding but I can darn sure follow directions. LOL!!!

    I tried Opt-In Skins in the past and didn’t like that one at all. I’m still not a fan of pop-ups so will probably never go that route.

    I appreciate this list though in case I can’t get OptIn Monster figured out. I’m hoping they can help me.

    Happy New Year!


    • Devesh says

      Hey Adrienne,

      I have been using OptinMonster here on WPKube, and everything seems to be working. I think it is one of the best all-in-one solutions for adding opt-in forms, as it comes with a ton of other features (as add-ons). You should wait till Monday, there support is great.

      But if you just need a plugin to add opt-in forms (no popups or slide-ins), then Optin Forms (by Boris Beo) is a fantastic plugin.

      Happy New Year to you too, Adrienne :). Hope you had a fantastic holiday season.

  9. says

    Amazing list Devesh.

    Thanks for including Plugmatter Feature Box in it. It’s always great to see your product listed on a blog that provides great value to its readers. :-)

    I have always been a strong proponents of premium list building plugins to boost email list and will continue to do so. Again, this a great collection.

    Anyway, wish you a great new year.

    • Devesh says

      Glad to hear that, Syed.

      List building plugins like Plugmatter, plays a huge role in building an effective email list. Thanks for stopping by.

  10. Carol Amato says

    Hello, Dev,

    Happy New Year! :-) Very good article, and I appreciate you sharing this info.

    You are absolutely right, list building should be a priority and we can all benefit from this info you’ve given.

    I agree with you – E-mail marketing is much more important than social media and can give much better results.

    I’ve heard of a lot of the plug-ins you’ve mentioned here, but those that are new to me are Optin Skin and Optin Architect.

    Personally I use LeadPages, and really like LeadBoxes in particular. So glad that I was taught from the beginning to start building a list early, so I have no regrets.

    Hope your Monday has been fabulous so far.


    • Devesh says

      My pleasure, Carol.

      I’m with you on building email list from early one, a lot of people ignore this, and focus on social media and other sources of traffic. What they need to do instead, is reduce dependency on Google.

      Optin Skin and Optin Architect are both great plugins, but if you are using Leadpages, I don’t think you will be needing either of the them.

      Hope your year is off to a great start, Carol. Thanks for stopping by.

  11. Michael Karp says

    Hi Dev,

    Great post man. Detailed, well-researched, and you’ve given people some solid info to make the right choice(s) for their site.

    I’m going to check out a few of them right now, and possibly recommend them to clients in the future.

    Have a good one,


  12. Katie says

    What about Magic Action Box? I have seen other bloggers recommend that plugin. Thoughts?

  13. Theresia Lee says

    Hey Dev,

    Thanks for the great list. I definitely agree with OptinMonster on top of your excellent list.

    Have you tried using it with Sendy.co? I personally think OptinMonster+Sendy is the ideal solution if you want to create and significantly grow your list without breaking your bottomline.

    OptinMonster doesn’t “natively” support Sendy. That’s why I’ve built a plugin to make them seamlessly integrate and play along nicely together. You may want to check the plugin here: http://appvisionaire.com/downloads/optinmonster-sendy-integration-addon
