Will Twilio automatically handle my short code’s replies to the keywords HELP and STOP?

Unlike a 10-digit (long code) phone number, Twilio does not handle your Short Code HELP & STOP replies, or your opt-out list. You should build this functionality into your own short code messaging application.

For information on carriers’ requirements for short code HELP and STOP replies, please see the following resources:

Industry standards for U.S. short code HELP and STOP
Industry standards for HELP and STOP for Canada short codes
