How to add your own Global Opt Out Message
Account Owners, Administrators, and Moderators can add, edit, and delete a default Opt Out Reply message for their organization. You will find this option in the administrator console with your global recommended replies. Select New Opt Out and enter your organization's preferred opt-out message, and then click the "Create Opt Out Reply" button.
Your administrator console and user messenger will now include this message by default when managing opt-outs. Scripts can be edited before completing the opt-out for better message flow. One click of "Complete opt out" will send the message and opt-out the contact. Un-checking the box will complete the opt-out without sending a message and cancel will close the opt-out menu without completing the opt-out.
