SMTP Authentication will allow your WordPress site to authenticate with the server before sending out a notification. This ensures all outgoing notifications from your site is from an authenticated source. In case your WordPress site is ever compromised, it also helps prevent your account from sending bulk emails and spam through your server without your knowledge.

We recommend two commonly used WordPress SMTP plugins:
  • WP Mail SMTP by WPForms
  • Easy WP SMTP by wpecommerce
To setup and configure a WordPress SMTP plugin, please follow the instructions outlined in the Related Article above.
