If you get a lot of new user signups on your website every day, then the number of emails you receive from Easy Digital Downloads may become annoying. If this is the case with your website, let me share with you an easy way to disable Easy Digital Downloads’ new user notification emails.
Just copy and paste this code into your functions.php file or create a new plugin with this code:
remove_action( 'edd_insert_user', 'edd_new_user_notification', 10, 2 );
The above code removes the function edd_new_user_notification from the hook edd_insert_user. This function is responsible for sending out email notifications for new users. The edd_insert_user hook is fired when a new user is added.
