WordPress is normally a terrible choice to send your emails because your web hosting server will be used to send the emails. Since it’s not optimized for this task, you end up with poor deliverability.

SMTP stands for “Simple Mail Transfer Protocol” and a server can be optimized to send emails using this protocol.

Below you’ll find the best plugins for integrating your WordPress site with SMTP, so you can send emails quickly and reliably. This will affect newsletters sent with plugins like MailPoet and transactional emails like the “thank you” emails your WooCommerce customers receive.

Which SMTP plugin is best?

Sending reliable emails used to be tough. With the help of various email service providers and integrated SMTP plugins for WordPress, it’s much easier for users with little to no coding experience.

Some of the SMTP plugins above offer a completely free plan so you don’t have to worry about periodic costs. What’s left to do is to pick an affordable email service that fits best with your goals and email needs.

Email service is no longer the playground of big tech companies like Google, Microsoft, or Amazon. When it comes to sending commercial emails, using newly launched mailers like Postmark, Sparkpost, Mailgun, or Pepipost can be advantageous. Some of them offer a forever free plan, too. So explore and choose wisely.
