WordPress SMTP: Guide & WordPress best SMTP plugins

Hello everybody, today im happy to present my complete WordPress SMTP guide. Coupled with my recommendation on WordPress best SMTP plugins. Moreover, we will also talk about WordPress SMTP configuration, WordPress SMTP settings and the WordPress mailing service itself.

Finally, for “dessert”, we will cover the method of integrating SMTP without plugins. So, without further delay, let’s get started!

Email Services In WordPress: wp_mail

By default, WordPress comes with a built-in mailing mechanism called: wp_mail. The core of this mechanism uses the native PHP Mail functions to sent emails. Meaning? Your emails will be routed and handled by the hosting’s email server by default. This could be a problem for a few reasons:

  • Your emails might get flagged as spam, if not initially, then somewhere along the road.
  • If you have traffic and your email activity is high, it is wiser to switch to SMTP. Due to the simple fact, it will most likely handle the volume in a better way than the native hosting email server.
  • Finally, and most importantly, the header of the email will display the hosting address. This could be bad due to the simple reasons you will want your branded domain there.

As you can see above, these are the major downsides of the native way WordPress handles emails.

The Solution: WordPress SMTP Email Set Up

We can solve all these problems mentioned above by switching to WordPress SMTP and configuring our WordPress SMTP Settings. By doing so we switch the default way of handling emails in WordPress. We connect our email account and route everything trough that Third-party email providers(Gmail, Gsuite, Yahoo, etc..).

  • Your emails will not go to the spam folder, you are using official accounts of a formal and well-established provider.
  • It is most likely that Google or Yahoo won’t crash under a lot of emailing 🙂
  • The mail headers will represent your brand and identity.

As you can see, we pretty much solved all the problems above. Now that we got that out of the way and we understand the differences between these 2 ways. We can go ahead and figure out how we go and implement this.

WordPress SMTP – Making The Transition

In WordPress this can be achieved in two ways:

  • With the help of a plugin
  • without a plugin at all, coding required.

Now before we dive into it, I would like to briefly break down some common definitions in the world of SMTP:

  • SMTP Host – the server hostname
  • SMTP Port – the port your server works on( usually 25 )
  • Encryption – if you have SSL/TLS encryption set
  • Username – the username for the account
  • Password – the password for the account

Now Allow me to go ahead and start with the first method. I’m going to go over the best SMTP Mailer plugins for WordPress.
