12+ Best WordPress Email Plugins in 2021: Marketing, Newsletters, and More

Searching for the best WordPress email plugins to boost your site’s email marketing efforts?

Because email marketing plays such a key role in most websites, you can find an array of WordPress email plugins that help with everything from growing your lists with forms to managing subscribers, sending emails, setting up automation sequences, and more (sometimes all in the same plugin!).

To help you find the best plugin(s) for your needs, we did the work to curate 12+ of the best email plugins for WordPress users in 2021 and beyond.

These plugins cover a range of features, but they’re all focused on one overriding goal – improving your WordPress site’s emails and/or email marketing.

Let’s get right to the plugins…

12+ Best WordPress Email Plugins

1. HubSpot

HubSpot offers an all-approach to email marketing (and marketing in general) on your WordPress site. You get a powerful customer relationship management tool (CRM), email marketing, marketing automation, scheduling software, ticketing system, and more in one package.

With HubSpot’s drag-and-drop form and popup builder, you can design your own custom lead generation forms that feed into the free CRM. Or, you can use your favorite form plugin and still send leads to your CRM.

From there, you can segment and tag your customers as needed. Then, you can easily use the drag-and-drop email builder to send them one-off messages or set up automation sequences and funnels.

For eCommerce stores, HubSpot also has a dedicated WooCommerce integration so that you can sync all of your store and customer details to HubSpot. You’ll also be able to set up eCommerce-focused automation like abandoned cart reminders and after-purchase emails.

Key Features:

  • Access your CRM and other features from your WordPress dashboard.
  • Flexible CRM to store your subscribers’ details, create segments, track activity, and more.
  • Send one-off emails to individuals or segments. Or, set up automatic sequences and marketing automation rules.
  • Drag-and-drop email builder, along with professionally designed email templates.
  • Drag-and-drop form and popup builder to create lead generation forms.
  • Integrates with most other popular form and list building plugins.
  • Get access to other ways to interact with your customers and capture leads, such as live chat and chatbots.

Pricing: The HubSpot CRM and WordPress plugin are free to use forever. There are optional paid plans to add more marketing features if needed.

Use It For: Use a single tool for your CRM, email marketing, marketing automation, customer support, and more.

2. WP Mail SMTP

WP Mail SMTP 12 best email service 2021

WP Mail SMTP is a slightly different take on a WordPress email plugin. Instead of helping you send marketing emails or set up automation like HubSpot, WP Mail SMTP helps you make your WordPress site’s transactional emails more reliable.

If you’re not familiar with the term “transactional emails,” these are the automatic day-to-day emails for things like password resets, form submission notifications, comment approvals, etc.

By default, the way that WordPress sends these emails often ends with them arriving in the spam folder (or just not sending at all). But with WP Mail SMTP, you can connect your WordPress site to a dedicated email sending service – called an SMTP service.

Using a dedicated service lets you be confident that your emails will always arrive at your recipients’ inboxes and avoid their spam folders.

Key Features:

  • Configure your WordPress site to send emails using a dedicated SMTP service. Works with virtually all popular plugins that send emails.
  • Dedicated API integrations for SendGrid, Mailgun, Gmail API, Sendinblue, and more.
  • Works with any SMTP server, including the SMTP servers that many WordPress hosts offer.
  • Send test emails to make sure everything is working.
  • Email logging (Pro).

Pricing: There’s a free version that will work for most sites. The Pro version adds more features for $99.

Use It For: Making your WordPress site’s transactional emails more reliable and avoiding issues with WordPress not sending emails.

MailPoet is a full-service email marketing and newsletter plugin that lets you manage everything without leaving your WordPress dashboard.

You can create forms to grow your subscriber lists, manage subscribers and create segments, and send emails using a visual drag-and-drop builder. It supports both one-off emails and automatic newsletters, such as a weekly digest that automatically inserts your latest blog posts.

If you have a WooCommerce store, MailPoet also includes built-in features for abandoned cart reminders and after-purchase emails, as well as revenue statistics to see how effective your email marketing efforts are.

To send emails reliably, MailPoet includes its own built-in SMTP sending service. Or, you also have the option to connect it to a third-party SMTP service if you prefer.

Key Features:

  • Manage everything from inside your WordPress dashboard.
  • Create forms and popups using the native WordPress block editor.
  • Supports one-off or automatic email newsletters.

4. MailOptin

MailOptin WordPress Email

MailOptin is a fairly unique WordPress email plugin because it can serve two different functions depending on which version you purchase:

  • Build your email list – you can create popups, notification bars, and other types of opt-in forms to grow your email list. This is the only focus in the free version and the premium version expands on its abilities with new list building features.
  • Send newsletters – if you use a supported email marketing service, the premium version also lets you design and send one-off or automatic email newsletters from your WordPress dashboard.

You’ll still need to rely on an email marketing service to manage subscribers and deliver the emails for sending newsletters. But you can design everything using the real-time WordPress Customizer.

Key Features:

  • Create email opt-in forms that connect to your email marketing service or CRM.
  • Different form options including popups, slide-ins, inline forms, notification bars, and more.

With it, you can use the native WordPress block editor to design the text of your emails. You also have the option to publish blog posts directly to your email subscribers, which lets you create your own Substack experience.

Newsletter Glue does not have its own email sending or list management features, though, so you’ll need to pair it with one of the supported email marketing services. These include Mailchimp, ActiveCampaign, Campaign Monitor, GetResponse, MailerLite, Sendy, and some other options.

This ability opens up some beneficial applications for email marketing. For example, let’s say you have an online course powered by LearnDash and you’re using the HubSpot CRM. You could use Uncanny Automator to apply a tag to a user when they perform a certain action, like passing a quiz or registering for a course. Then, you could use that tag to have HubSpot fire off an email to that person.
