When using an Alphanumeric Sender code, recipients cannot reply directly to the message because the "sender" is a brand name (e.g., ABCDEF) rather than a numeric phone number. Moreover Alphanumeric sender codes supports one-way communication only. This prevents using standard OPT OUT Keywords like "STOP". To maintain compliance and a positive user experience, businesses must provide alternative opt-out methods such as hosted preference centers or secondary numeric codes like short or long codes.
To ensure a compliant and user-friendly messaging program, use one of the following two primary methods:
This is considered the Best Practice for Alphanumeric sender codes. It provides a seamless transition for the user and allows for more granular control over communication.
How it works: Include a shortened, trackable URL at the end of the message (e.g., brand.co/stop). Or use the preference center merge field in the SMS.
If you have a secondary numeric code (Short Code or Long Code) in Marketing Cloud Next, you can direct users to that specific number to unsubscribe.
How it works: Include instructional text such as: "To stop, text STOP to +XX XXXX XXXXX" or "Text STOP to XXXXX."
Considerations:This requires the user to manually open a new message thread and type in a number, which is less convenient than a link.
