Moderation Question/Request

The speed of email sending is something to take up with your host. If your host is like most hosts these days, they would probably prefer that you do not use them for sending email and instead send using SMTP.

The ‘fastest’ sending for email will be a commercial API service like SES or Sparkpost.

add_filter('uwp_send_admin_email_to', 'uwp_send_admin_email_to_cb', 10, 2);
function uwp_send_admin_email_to_cb($site_email, $message_type){

    $email_to = array();
    if('mod_admin' == $message_type){
        $email_to[] = get_option('admin_email');
        $email_to[] = 'info@someadmin.com'; // Change to your email address
        // $email_to[] = 'info2@someadmin.com'; you can add more email addresses like this
        $site_email = $email_to;
    }

    return $site_email;
}
