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

<h4>Redirect all email sent by WordPress to the admin’s email address.</h4>
When activated, this plugin will send all email sent by WordPress to the admin email address instead of the intended recipient.
It uses the wp_mail filter to modify the “to” address for all email sent by WordPress. When active, all email sent through WordPress’s wp_mail() function is rerouted to the admin email address as configured under “Settings – General”.
One of its uses is to allow the creation of new users during testing. WordPress requires user email addresses to be unique, and sends confirmation messages to these addresses. Using this plugin, you can use fake addresses, and still receive the activation links.

Mail Caesar!

I love plugins which you install and just use without the hassle to go through a bunch of confusing options and settings. This plugin is such a lean and clean little helper, eg. if you need to test functionality for a new website and don't want the mail to be sent to your client.

Bonus for the superb plugin name! 👍🏻

Cool stuff

Redirect all email sent by WordPress to the admin's email address.
