CL Simplest SMTP


I've been using Carlos's SMTP plugin for WordPress, and honestly, it's exactly what I needed. Super easy to set up, no complicated menus or unnecessary extras. Within minutes, I had it up and running, and it fixed all my email delivery issues like a charm.



The best part? It's lightweight and doesn't slow down the site, which is a big win. Plus, it works perfectly with providers like Gmail and Outlook—I haven’t had a single issue since installing it.



If you're looking for something simple, effective, and hassle-free, this is the plugin for you. Great job, Carlos!


Fantastic!


Great plugin for configure your own SMTP mail server. Simple, easy to install and works fine. And the best feature, you can define the data in variables in your wp-config.php. 



It's an excellent choice for me.

Carlos nails it!!



We are pleased to have this simple plugin without the useless options that others add.Thank you!!

⚠️ IMPORTANT NOTICE: THIS PLUGIN IS NO LONGER MAINTAINED ⚠️
Active development and support for System Requirements Check have officially ended.
<ul>
<li>Why? The technical environment has evolved, making this plugin antiquated. Web standards have moved away from client-side technologies like Adobe Flash Player and Java Runtime Environment (JRE), which this plugin was originally designed to check. Modern web browsers and WordPress core now handle environment baseline checks natively, rendering this specific client-side check obsolete.</li>
<li>Closing Date: This plugin will be officially closed to new downloads on the WordPress.org repository on December 31, 2026. </li>
<li>What this means: No new features, bug fixes, or security patches will be released. The plugin is provided “as-is.” Existing installations will continue to function but will receive no further compatibility updates.</li>
<li>Support: The support forums will no longer be monitored.</li>
</ul>
Thank you to everyone who supported this project over the years!
