WP Mail Debugger

I "found" this plugin when its creator presented it at WCPhx 2020. Its extremely easy to use, and is helpful in a day and age when SPFF and DKIM issues make debugging mail tough. Show your users the mail is going out. Or as a plugin developer, use it to review output.

This is so good

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 ;-)
