Functions.php : Disable New User Registration Admin Emails

This allows you to disable the new user emails sent to the default admin email set under Settings > General, ‘Administration Email Address’ without installing an additional plugin.

To start,make sure you have admin access to the backend of WordPress. Because this requires you to have the ability to add/edit the code snippet below onto the functions.php file within the current theme folder.

				
					//Disable the new user notification sent to the site admin
function smartwp_disable_new_user_notifications() {
//Remove original use created emails
remove_action( 'register_new_user', 'wp_send_new_user_notifications' );
remove_action( 'edit_user_created_user', 'wp_send_new_user_notifications', 10, 2 );
//Add new function to take over email creation
add_action( 'register_new_user', 'smartwp_send_new_user_notifications' );
add_action( 'edit_user_created_user', 'smartwp_send_new_user_notifications', 10, 2 );
}
function smartwp_send_new_user_notifications( $user_id, $notify = 'user' ) {
if ( empty($notify) || $notify == 'admin' ) {
return;
}elseif( $notify == 'both' ){
//Only send the new user their email, not the admin
$notify = 'user';
}
wp_send_new_user_notifications( $user_id, $notify );
}
add_action( 'init', 'smartwp_disable_new_user_notifications' );
