Blocca invio Email


Stops outgoing emails sent from WordPress. This plugin stops
outgoing emails generated by WordPress core, plugins, and themes.
Emails sent using the wp_mail() function, will not be sent.
In the case where an author does not use the recommended wp_mail()
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 wp_mail() 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

NOTE: If using the PHP mail() function directly, this
plugin will NOT stop the emails.

  2. Activate Stop Emails through the ‘Plugins’ menu in WordPress.

Where do the emails go?

The emails are lost forever.

Why are some of my emails still being sent?

Most likely, this is due to a plugin you have running.
There are two different things the plugin could be
doing to cause emails to still be sent.

  1. The plugin is overriding our overriding of the sending mechanism.
  2. The plugin is calling the PHP function mail() directly.

Unfortunately in either of these cases, this plugin will not be able to stop
the email.

I want to log the emails that are stopped

You can enable logging of stopped emails on the
admin menu page Settings > Stop Emails.

Emails will be logged to your PHP error log.

Why would I want install in the mu-plugins directory?

Activating a plugin normally requires logging into the site.
Installing the file in the mu-plugins directory allows you to
activate the plugin without logging in. This can be
helpful when setting up an existing site locally.

I develop a lot of WordPress sites and normally this isn’t an issue. But I’ve been developing a membership site and normally when I do a site that includes users and their email addresses I just click on the box that asks to send the user notification of their password. But on this particular site the users need to be approved. I’m using BuddyPress and a plugin that allows user moderation, BP Registration. The problem came in when when I had to start approving members so they would show up in the list. These were existing members so they needed to be active. I started getting emails asking what the heck was going on. Each of my members were getting notices that they had been approved. I had to take the time to explain to each one of them what had happened. Very time consuming, very embarrassing. Glad I found this since I have several members that still need to be added. I added myself as a user and checked the box to notify me of my password. No email! I changed my password. No email! I approved my account. Still no email! Works perfectly. I can now develop in silence and not worry about alerting/confusing members. Thank you for your work! Allen

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.

This works great. I had used it months ago for something else. But I needed to migrate a 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.
