An incredibly useful tool

This kind of functionality is so incredibly useful. Normally you never need to check it, but what if users of your site say that something is up with the emails they’ve been receiving. How will you check what is actually being sent by WordPress? This plugin waits quietly, logging everything, ready for when you need to check it.

Essential plugin, which I install on all my sites.

The developers are responsive an have fixed the issue I recently had.
