A light weight plugin that helps with email debugging by providing the following features:
<ul>
<li>Log all emails sent by WordPress</li>
<li>Display an HTML preview of the logged emails</li>
<li>Disable email sending</li>
<li>Search by anything</li>
</ul>

Mail Grab

As a developer, this plugin is really helpful to me. It has a nice place where I can see a history of the mails sent while debugging my things.

The disable feature is especially great!

P.S. Works on a client website, but not locally for some reason. I suspect it might be an issue with my environment. Will update to give feedback in case somebody else has issues.

Clean and simple

Debug WordPress emails with ease. Log all emails and disable email sending if needed.
