Stops outgoing emails sent from WordPress. This plugin stops 
outgoing emails generated by WordPress core, plugins, and themes. 
Emails sent using the <code>wp_mail()</code> function, will not be sent. 
In the case where an author does not use the recommended <code>wp_mail()</code> 
function and instead sends the email using another mechanism, an email will 
still be sent.
This plugin allows you to suspend sending emails when doing development work. 
Any calls to <code>wp_mail()</code> will fail silently. WordPress 
will operate as if the email were sent successfully 
but no email will actually be sent.
On the admin menu page Settings > Stop Emails, there is the option 
to log all emails to the PHP error log. By default this logging is 
disabled.
NOTE: If using the PHP <code>mail()</code> function directly, this 
plugin will NOT stop the emails.

Stop Emails

Simply Works

This works great. I had used it months ago for something else. But I needed to migrate a Ning.com website with members into a new Buddypress site. I had to make sure the members were not emailed or pinged. This plugin stopped all outgoing emails to all the members.

Works Great!

Worked out of the box for me on a VPS; we were developing a system in parallel to an existing site and someone else installed this instead of using our existing process. I learned of a new plugin and a new way of doing things for WP. Very impressed.

Great turn-key solution

Excellent plugin! Easy, effective, bloatless.

Easy and Effective
