Twilio, by default, handles standard English-language reply messages such as HELP, INFO, STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT in accordance with industry standards. If the activist's response matches one of these keywords, they will receive your default help or unsubscribe message. You can set custom Help Responses and Unsubscribe Responses in the box. All other responses will be filtered according to the process laid out in this document.
Note that this won't work for the first two business days after it has been set. We have to do some things on our end first!
