There are A LOT of SMTP plugins for WordPress, some uses third-party libraries with no too much luck, others looks like the same plugin (almost identical source code) but with different name…
Most of them overwrites from address and from name fields ALWAYS, breaking functionality of some other plugins that send emails using wp_mail() function.
So the history repeats again, I can’t find one simple plugin that fits my needs, so I created one for myself and share it with you in the hope that you’ll find it useful.
If you’re happy with the plugin <a href="https://wordpress.org/support/plugin/sar-friendly-smtp/reviews/?filter=5" rel="ugc">please don’t forget to give it a good rating</a>, it will motivate me to keep sharing and improving this plugin (and others).

SAR Friendly SMTP

It probably works fine, but I uninstalled it immediately after activating it because it clutters up the admin menu with a new top-level item, even though you only interact with it once.

Adds another top-level admin menu

A friendly SMTP plugin for WordPress. No third-party, simply using WordPress native possibilities.

WP SMTP Mailer – SMTP7

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

Quick and handy


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.


Simple yet effective
