Do you want the best SMTP plugin to fix email delivery issues on your WordPress site?

SMTP improves the reliability and deliverability of email notifications and transactional emails sent by your WordPress website.

While this seems really technical, SMTP plugins make it easy for anyone to apply these changes to their site.

In this guide, we’ve handpicked the best SMTP plugins for your WordPress site that will fix email delivery issues and make sure your emails hit the recipient’s inbox.

First, let’s be clear on what SMTP is and why you need it.

What is SMTP in WordPress?

In technical terms, SMTP is a communication protocol used for sending email messages between servers. It stands for Simple Mail Transfer Protocol,

In the context of your WordPress site, SMTP can improve email delivery rates. It helps you set up the right configurations so that every email you send from your WordPress site gets delivered. It also makes sure the email hits the recipient’s inbox and doesn’t go into the spam folder.

Aside from that, SMTP also helps in the following ways:

  • Reduce spam flags
  • Customize email ‘From Name’
  • Monitor the status of email delivery
  • Test and troubleshoot any issues

To understand how SMTP works, you need to know that by default, WordPress uses a built-in PHP mail function to send emails. This method may not work reliably, especially in shared web hosting environments.

This is why you need an SMTP plugin. Once SMTP is set up, all email notifications generated by your WordPress website are sent through the configured SMTP server.

This includes contact form submissions, user registration emails, password reset emails, and WooCommerce order notifications.

You can usually test the connection to ensure that your website can successfully communicate with the SMTP server. Plus, SMTP allows you to authenticate your website when sending emails, reducing the likelihood that your emails will be flagged as spam.

In a nutshell, SMTP will help you avoid common email delivery problems and enhance the professionalism of your communication.

With that said, let’s check out the list of the best SMTP plugins.
