Invitees can opt out of, opt back in to, or get general help about the text messages that your workflows send them by using one of the standard responses below:
To opt out of text messages, reply STOP.
Note: You will not be notified if your invitee has opted out of texts messages.
To opt back in to text messages, reply START.
Note: Invitees must respond to the same number for text messages they originally opted out of. If they reply to a different number, then they will not be re-enrolled into text messages.
To get information from Twilio on text messaging, reply HELP.
