Top 30 WP SMTP Plugins for 2020 | WordPress SMTP Plugins

Published : January 1, 2020 | Updated : May 23, 2024

If you are working on any WordPress sites that accept public registration then your WordPress site needs to send a lot of transactional emails to its users. These can be, in case of e-commerce emails regarding order confirmation emails, password reset emails, etc. These emails can be sent over using a simple WP SMTP Plugin.

Millions of messages get exchanged over the networks regularly, and almost all sent from websites use some form of SMTP Plugin. Alternatively, sometimes sending and receiving emails from your WordPress creates serious headaches and pain. This is because, with the native WordPress email solution — wp_mail, a significant portion of those emails will likely end up in recipients’ spam folders. And this is something that you do not desire? Am I right?

Once when an email is sent across, your hosting provider becomes responsible for properly delivering the email to the concerned recipients. And when this does not happen the email reaches the spam folder. Addressing such kind of issues takes time and effort. But fortunately, the simple solution to this comes in the form of SMTP Plugins that are available in the WordPress repository. And thus the hosting provider can be easily changed simply by installing the SMTP Plugin on your website.

What is an SMTP Plugin?

Before we look for some great SMTP plugins, let us spare some time to understand what SMTP does and how it is of use to us. Since not all emails are transferred successfully as some of them get bounced over the network, the email open rate gets lower. This is where the SMTP comes handy.

SMTP, basically stands for Simple Mail Transfer Protocol which is a protocol used for sending and receiving emails over a network. So how SMTP works is that when you send an email, its server breaks it down into its relevant parts. This helps move it from your email client to your recipient’s email client. And therefore most of the emails that are in your inbox probably have come from an SMTP server.

With an SMTP Plugin installed on your website, you can order your WordPress site to send emails via a properly-configured SMTP server, rather than your WordPress site’s server. And with this setup by your side, your WordPress site will send the email to the SMTP server. This then processes the email and sends it on to the proper destination which here, in this case, is the recipient’s inbox.

Now because the SMTP server is configured in such a way that it handles sending emails with proper authentication in place, your email deliverability rates are improved and the chances of your email making it to recipients’ inboxes are also better.
