With over 22 years of email delivery success, SMTP.com is the trusted transactional and email relay provider for over 100,000 businesses worldwide. This WordPress integration for SMTP.com enables you to send and track your emails seamlessly.
Don’t worry about maintaining your email server or taking care of its IP reputation, forget about dealing with ISPs like Gmail, Yahoo or Microsoft in attempting to understand why your email isn’t reaching its destination. SMTP.com manages all this on your behalf. Simply create a SMTP.com account to <a href="https://registration.smtp.com/?afid=wpplugin" rel="nofollow ugc">get started</a> and set up this plugin. Although this plugin is free you will need a paid subscription with SMTP.com to send emails from your WordPress site.
You can send emails from your WordPress site using the SMTP.com API or the standard SMTP protocol. Our plugin will suggest the best way for you to send email even if your provider has restricted access to outbound internet ports. Either way, SMTP.com will still ensure your email gets delivered.
Another useful feature provided with our WordPress plugin is the ability to track your email delivery from within the plugin itself. See the results of your recent sends to ensure successful delivery or identify the reason why your particular email hasn’t been delivered.

YaySMTP – WP Mail SMTP with Email Logs, Tracking & Reports

I just wanted to come and say thank you for this amazing plugin. This is basically the only plugin that works for multisite global configuration. 

I lost 45 minutes trying different plugins for my multisite network, basically i tried all those plugins with millions of installs and none of them do what this plugin does.

Great job!

Excellent! Great job.


This is the ultimate SMTP plugin. It even has email logs, which is a must-have. It's incredibly easy to use, and the developers are available right away! It's truly excellent.


The best SMTP i've tried


Happy to finally find this plugin. Simple to setup and Microsoft 365 is free on this one ! :)



Thanks you the team for this amazing plugin ;-)
