How to Disable Default WordPress Emails
If you want to use BNFW to disable a default WordPress email, such as the one that is sent to the admin when a user changes their password, all you have to do is to create a notification for the one you want to disable, then set it to ‘Notification Disabled’ in the ‘Save Notification’ meta box in the top right of the screen. In this example, you would create a notification for ‘Password Changed – For Admin’ within BNFW, and then set that ‘Notification Disabled’.
Once this is done, this default WordPress notification should no longer be sent.
Depending on your settings, because of how WordPress is set up, you may need to perform an extra step in order to override the New Comment and Comment Awaiting Moderation email notifications. To do this, please un-tick ‘Email me whenever anyone posts a comment’ and ‘A comment is held for moderation’ under Settings > Discussion in the WordPress Admin.
