If you’re using WHMCS to manage your cPanel shared servers, this is probably a request that you’ve received a few times. You have clients that are set up to pay invoices automatically from their credit cards, and they’d rather not receive the “Invoice Created” or “Invoice Payment Reminder” emails every month.
Normally WHMCS only allows you to disable these emails globally but, by making use of the EmailPreSend action hook, we can set up a list of clients not to receive these.
To get started just download the following script, change the file extension to
.php, edit it to set up the
$client_ids and place it in your WHMCS
Please note, this script doesn’t disable only the automatically sent invoice notification emails, but also blocks manual sending of these for the selected clients.
