Opt-Out Keywords for SMS Messages in Marketing Cloud Next

Every SMS sender code reserves keywords that recipients use to opt out of receiving messages. These keywords are always reserved.

• STOP
• QUIT
• CANCEL
• END
• UNSUBSCRIBE

Note Only short and long codes support opt-out keywords. Alphanumeric sender IDs don’t support two-way messaging, so recipients can’t reply to opt out.

A marketing admin can assign custom opt-out keywords to sender codes in Salesforce Setup. In the body of your SMS message, include one of these keywords and brief opt-out instructions.

To opt out, a recipient must reply to the sender code with an opt-out keyword appearing before the first space in their message. Salesforce immediately unsubscribes the recipient from all messages from that sender code.

Example

Try one of these SMS opt-out instructions that are fewer than 25 characters:

• Text STOP to opt out.
• Reply QUIT to end.
