How to find a suitable WP newsletter plugin

WordPress is a very popular content management system, mainly because of the huge number of available plugins. The official plugin directory offers almost 1,000 different WordPress newsletter extensions. So how do you decide which one is the right one for you? Here are some criteria to look out for:

  • GDPR compliance: You must ensure that newsletters comply with the GDPR. Some plugins integrate support for GDPR compliance, for example, by including a double-opt-in procedure. GDPR compliancy is a good idea in an increasingly connected world.
  • Language: Depending on the primary language you use on your website, you may want to select a WordPress newsletter plugin that includes a language extension.
  • Scope: Some plugins only integrate the newsletter sign-up form which means you’ll need to combine them with additional plugins. Other extensions offer more complete solutions.
  • Presentation: Plan in advance how you wish to integrate the newsletter registration form. If your newsletter is optional, for example, an eye-catching pop-up window may not be as effective.
  • Compatibility: Whichever plugin you choose, ensure that it is compatible with the WordPress version you are using and, if applicable, with the newsletter service of your choice.
  • Costs: Plugins vary widely when it comes to pricing. Many extensions are designed in such a way that you can access basic functions free of charge but need to pay for extended features of the respective WordPress newsletter plugin.

Mailchimp for WordPress (MC4WP)

Mailchimp for WordPress links WordPress with the Mailchimp email marketing system. This is a great option for beginners, as it allows up to 10,000 newsletter emails per month to be sent to 2,000 subscribers free of charge. Those who need a larger volume can purchase it on a monthly subscription basis. The same applies to the WordPress newsletter plugin which is basically free – but for an annual subscription fee you get access to premium features like additional forms or email notifications.

Before you can use the WP newsletter plugin, you need to link your WordPress using your Mailchimp API key. Once entered, the plugin confirms the integration. After that, you can create as many registration forms as you wish, adjust settings and positions. MC4WP displays the HTML code for these directly in the backend.

The newsletter subscription forms are:

  • User-friendly
  • Optimised for mobile devices
  • GDPR-compliant (double opt-in can be (de)activated)
  • Suitable for setting up automatic forwarding
  • Suitable for embedding in posts or pages via WordPress shortcode



✔ Decent editor in the free edition, excellent editor in the paid edition

✘ Customisation options are limited

✔ 10,000 newsletters to up to 2,000 users per month free of charge

✔ All forms are automatically responsive

MailPoet is an all-in-one solution for designing and integrating your WordPress newsletters and notification emails. Similar to Mailchimp, the extension can be used for free, up to a certain quota.

Apart from a higher newsletter volume, paying customers get additional features such as premium support, detailed analyses, and the option to send emails via their provider of choice or the MailPoet service.

To design your newsletter, MailPoet provides a user-friendly editor in the backend and a handful of templates. Drag and drop fields, headers, images, etc. to the desired location. Alternatively, you can redesign your newsletter registration form from scratch.

The forms you can create with the WP newsletter plugin have the following features:

  • Optionally presented as pop-up, slide-in, fixed bar or box at end/edge of page
  • GDPR-compliant (double opt-in can be (de)activated)
  • Individual colour design of background, font, and frame
  • Programming in CSS possible

WordPress newsletter: why GDPR compliance and double opt-in are important

The web is accessible from anywhere in the world. This means that your subscribers and page viewers may be based in the European Union. As of May 2018, the General Data Protection Regulation (GDPR) applies across all EU member states. This means that the following now applies when sending newsletters: The recipient has to consent to the processing of their personal data and the processing needs to be legally compliant. In addition, you must be able to provide information at any time about how a subscriber’s personal data such as an email address is stored and used.

However, the GDPR doesn’t stipulate that consent must take the form of a double opt-in procedure. If you don’t issue a confirmation email to consent to a newsletter subscription, you’re technically not in violation of the GDPR. However, since the regulations stipulate that you must be able prove at any time that a user has agreed to receive your newsletter, you can use double opt-in as a proof of this requirement.
