7 Best Email Marketing Plugins for WordPress in 2019 (Free and Paid)

Email marketing, WordPress plugins

Email marketing is the most effective solution for connecting with your audience and keeping them updated with your content.

Most people find your website, read some information, leave and then never return. Only a few of them really do something that will boost your conversion rate. Wouldn’t it be great for your business to convert some of those people to subscribe to your mailing list?

The most important asset of your online presence is your email list.

No, it´s not the design of your WordPress theme or your content. These just help a lot to get your email subscribers. But if you’re not gathering prospects, they don’t do you much good.

As you build your email subscriber list, promoting your new posts becomes faster and more effective. You can send a notification to thousands of interested people who want to read your content and get highly-targeted traffic to your website.

To get acquainted with the world of generating leads via email, I will list some of the best free and paid WordPress plugins for email marketing. Let’s start with the best.

1. Thrive Leads

The Thrive Leads plugin is definitely located at the top of our list in case you don’t want any compromises in your email list-building strategy. We recommended it to all of our clients and they’ve witnessed duplication and even tripling their conversion rates after installing and configuring it properly.

What makes Thrive Leads special is time-saving, easy handling without any programming or coding knowledge.

Below is the list of its potential benefits to your online presence.

More Opt-in Forms

Unlike the vast majority of plugins on the market, there are several types of forms available:

  • Classic Sign-up Box – On the right that stays always in the field of vision and not just above the fold
  • Pop-up Box
  • Sticky Ribbon – (Since ThematoSoup is one of the sticky header plugin authors, we can confirm that the Thrive team made a serious shift when it comes to this type of add-on, both from the frontend and backend)
  • Inline Forms – Especially suitable for bloggers who have major following. The main attention is always on the text, and with this function it is possible to increase the number of email subscribers up to 200% compared to the classic sign-up box on the right
  • 2-step Opt-in – Suitable primarily for marketers who want to build a relevant email list. The site visitor must do 2 steps – click on the link and sign in with an email.
  • Slide In – Display the relevant opt-in boxes on the right side of the blog and customize for every blog post
  • Screen Filler – Ok, we admit that we did not use this. It should increase conversion rates, but I do not personally like to bomb our visitors that much
  • Content Lock – A recommendation for articles that have viral potential. Especially how-to articles. Set up some worth of content in exchange for email
  • Welcome Mat – Similar to Screen Filler
  • Multiple Choice Form – Engage your visitors!

Advanced targeting

Every marketer knows that today it’s more important than ever to make content relevant. It’s the same with email marketing plugins. For one of our clients, we installed a special email form that is relevant to the topic of each blog post. For example, if an article was about WordPress Security then the form offered a whitepaper on security. This way, the conversion rate has risen to 350%!

Advanced statistics

Even though we are marketers and the installation of Google Analytics code is not a problem, the built-in thrive leads statistics help us set it a lot faster and measure the effect of the set up email forms.

Here are the reports you get access to:

  • Conversion Report
  • Conversion Rate Report
  • Cumulative Conversions Report
  • Comparison Report
  • List Growth
  • Cumulative List Growth
  • Lead Referral Report
  • Lead Tracking Report
  • Content Marketing Report

A/B Tests

Pay special attention to A/B tests when installing the plugin. In relation to the time you put into configuring and installing the plugin, your investment should return X10 times. When you set it up correctly, the email plugin works on its own!

What to measure

  • Types of opt-in forms – does a content locker work better or a pop-up box
  • Different email triggers – does it work better with a 3-second pop-up or with an exit-intent function
  • Different offers – do you achieve better conversion rates using an e-book or a free course that you offer?

Trigger options

Exit trigger – when someone tries to get out of the site, the form is shown

Time trigger – email form does not have to be boring – show it only to those who showed interest in your content

Scroll Trigger – similar to time trigger, the email form appears after the visitor scrolls more than a specified percentage of the page

Click Trigger – the form appears after clicking on a particular item or link

Precise targeting

This is the option we used to increase the number of leads for one of our clients. The tactic is simple – show the relevant (email) offer to each visitor.

  1. Hi Ivan!

    We’re so sad you forget about us :'(

    Maybe it’s because you didn’t know us :) We’re a brand new Newsletter plugin for WordPress called Jackmail and the first one ever to include a routing platform so you don’t have to fiddle with complicated smtp settings.

    Check it out :
    Plugin, support, features and updates are free! You only pay above the free plan (which is 3000 emails per month for free !)

    Have a great day :)

  2. This is an awesome list. But I think as a beginner one should start with MailChimp, which is free for first 2000 subscribers. This is a huge number of subscribers for a beginner and kick-start email marketing. Many thanks for sharing this list.

    1. I agree. Santanu. Everyone should try MailChimp. That’s why it’s in the article, maybe not as high as it deserves, but it’s there :)
      Thanks for the comment and for stopping by.

    2. Got mailchimp activated but d settings took me to some merri go round tour that ended up asking me to pay.
      Thought you said for the first 2000 subscribers list its absolutely free, can’t experience it here,or there an alternative way?

  3. Thank you for the list.

    I also as a beginner started with MailChimp.
    Now I use Mailster from CodeCanyon. Never regretted or looked back.


  4. Helⅼo would you mind letting me know which web host
    you’re working with? I’ve loadded youг blog in 3 different
    web browsers and I must saаy this Ьlog loads a lot faster then most.

    Can you recommend a good web hoѕting provideг at a reasonable price?

    Kudos, I apprecіate it!

  5. According to Optin Monster “Over 70% of your visitors do just that and never return”
    and thats true, we have noticed this in our clients website and when we suggested them about Optin forms to collect emails and start taking actions, their sales started increasing.

    Everyone should at least try once and do A/B testing with it. Check what is working for them and then take the next step.

    You have covered the most important plugins that anyone will love to go with. The only draw back is “for a newbie it’s costly” like SumoMe shows data only for past 7 days and if you want to check for more days you have to pay.

    1. You’re right on both of the statements. A/B testing and collecting emails and prospecting is what everybody should do and yes, it can be costly for newbies, but you’ve got some free options as well.

  6. Hey Ivan, thanks for sharing the email marketing plugin list. OptinMonster is helps to grow email list & increase subscribers using pop-ups and high converting opt – in forms.
    IMO beginner should start with Autopitch, which is 30 days free trial with 2000 contacts & 2000 emails.

  7. A great comparison of the two veterans of email marketing, Ivan.

    I have an account with many autoresponder services. I tend to prefer Aweber, but I think it is just because I started with it and I’m just more used to it.

    However, both companies offer a great service and are very easy to use, with an almost self-explanatory user interface.

    The reason why I have an additional GetResponse account was to have buyers from JVZoo automatically added via API using single opt-in. As Aweber allows this meanwhile too, it became obsolete.

    With the recent release of their marketing automation tool, GetResponse made another great step forward.

    Although I just had a fast look at it, it seems to be much more powerful than Aweber’s campaigns which were released a while ago but lacks a lot of necessary functions.

    If I would get started now and had to decide between Aweber and GetResponse, I’d choose GetResponse, mainly because of their new automation tool.
