When you send CEMs by email, you may offer one or both of the following unsubscribe methods:
- sending an email; and/or
- clicking on a link that will take the user to a web page where he or she can unsubscribe
When you send CEMs by text message, then you must offer both of the following unsubscribe methods:
- replying to the text message with the word “STOP”; and
- clicking on a link that will take the individual to a web page where he or she can unsubscribe
See a suggested unsubscribe notice in the Model Language (PDF).
