12 Best WordPress Email Plugins of 2025 (Hand-Picked)

We’ve all been there: Waiting for the account activation email that never came. Or the password reset link that never arrived. Blame it on the “WordPress-Not-Sending-Emails” issue, but it’s no fun having to contact support for such stuff.

As a business, you need to ensure that such key email communications — or transactional emails — get delivered instantly to your users.

Not just that, your marketing emails (think newsletters, lead nurturing drip sequences, and promotional/sales campaigns), too, must land in time in your subscribers’ inboxes (and not hours later in their SPAM folders!).

WordPress email plugins are the solution most people use.

Trusting the default WordPress email system and your web host for a 100% deliverability of your transactional and marketing emails is not a good idea for various reasons.

Your web hosts usually have daily email sending limits and sometimes can even have compromised reputations on shared hosting.

To ensure good deliverability of all your emails, you need to use some of the WordPress email plugins that let you send your WordPress emails via trusted email sending services. Let’s look at the best WordPress email plugins that let you do this.

Here goes.

What Makes the Best WordPress Email Plugin?

Here are some key factors to consider when choosing the right email plugin for your needs:

• Reliable email deliverability: You want your emails to reach recipients’ inboxes, not their spam folders. This often requires sending emails through trusted SMTP providers to improve email delivery.
• Ease of use: No one likes complicated things, and integrations can be jarring to do. Having a setup wizard that guides you through setting up the integration and a UI that is self-explanatory helps in the long run. Plus, workflows that are optimized to be simple, rather than filling the screen with hundreds of options, are a nice thing to see.
• Comprehensive email marketing features: The most common use case for WordPress email plugins is to automate email communications. Like sending newsletters, or email sequences after someone joins an email list. Look for features that can reduce your workload and help better collaborate with team members.

• Integration with other tools: All-in-one solutions are expensive, and are not very good. You can use many plugin combinations to get the most needed functionality to manage your email communications. However, they need to complement each other properly.
• Customization and design flexibility: Customizable templates and design tools to allow you to create emails that align with your brand’s aesthetics.​
• Compliance and security: Robust security measures to protect your email lists and campaign data from unauthorized access.​

I do consider these qualities while testing email plugins listed in this guide. By prioritizing these features you get the tools that you can trust for day-to-day work.
