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
