Reserved Keywords

The following keywords are always enabled and cannot be changed, in accordance with industry standards:

  • STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, and QUIT unsubscribe a user from a Campaign.
  • START and YES re-subscribe the user from a Campaign if they have previously unsubscribed. If the person texting START or YES is already subscribed, or is a new participant, their text will be treated as a normal response. For this reason, you can use YES or START as a keyword for an inbound campaign.
  • HELP and INFO trigger a standard reply: "Reply STOP to unsubscribe. Msg&Data Rates May Apply." To prevent unwanted behavior, never instruct users to text HELP or INFO to one of your polls as a response to a question. The reply message cannot be changed for long code (standard) phone numbers, but can be customized for short code numbers. More information on long vs. short code numbers in Shortcode vs. Longcode.

Do not use reserved keywords STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT, HELP, or INFO as prompts to initiate a campaign. For example, instructing users to "Text HELP to [number] for help with your loans" will trigger the standard reply above rather than beginning a poll.

Note: Reserved keywords only trigger special behavior if they are texted in as the only word in the incoming text message. For example, keywords actions will not be triggered by "Help with loans" or "Stop signs at dangerous intersections."

Spanish Reserved Keywords

ALTO (stop), INICIO (start), and AUXILIO are reserved as Spanish equivalents of the above English keywords. These words also cannot be used to initiate an inbound poll.
