My customer sent the word
QUIT in response to one of my Text notifications. Now, I can't send them any messages. How do they change it so they can receive messages again?
Zendesk uses Twilio as our provider and by default they handle standard English-language reply messages such as
CANCEL, in accordance with industry standards. When the customer sends one of the above words, they will be sent the following message:
"You have successfully been unsubscribed. You will not receive any more messages from this number. Reply START to resubscribe."
It is currently not possible to customize the default response triggered by these keywords. However, to receive messages again from your number, the customer will need to reply with
INFO are also key words.
Twilio does not forward HELP/INFO messages to your incoming message webhook. So these one word messages will not create tickets in your Zendesk account.
