WP SMTP Mailer – SMTP7

Takes 2 minutes (at most) to set up and works perfectly.

Quick and handy

Good plugin


It's a no-nonsense way to set up SMTP. I use Brevo for the relay server. They have a nice free tier. Combined with Brevos's easy-to-find API key, it's no sweat to have emails sent from your domain. For example, From address: your.name@yourdomain.com From name: Head Editor 



Getting an email sent to you@yourdomain.com is a whole other can of worms. But it's nice that this plugin doesn't have that. It keeps the settings simple.
