Managing Opt-Outs on Twilio Channels
Opt-outs are common among SMS and IVR services. According to the TCPA, your contacts should have the ability to do so at any time. Use this guide to learn how to track and manage these contacts via Twilio and your Nyaruka account.
When a contact sends: STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT to one of your Twilio numbers, Twilio will prevent them from receiving any additional messages until that contact responds START. Specifically, they'll receive the following message:
"You have successfully been unsubscribed. You will not receive any more messages from this number. Reply START to resubscribe."
When that contact resubscribes, they'll receive the following message:
"You have successfully been resubscribed to messages from this number. Reply HELP for help. Reply STOP to unsubscribe. Msg&Data Rates May Apply."
When Twilio notifies us that a contact has blacklisted one of your Twilio numbers, we place that contact in the default 'Stopped' group in your account's Contacts tab. The contact is removed from all other groups and specially marked so that any outbound message attempts are blocked.
Have Twilio notify you of errors–like the 21610 blacklist error.
For more information on proper SMS or IVR-based communication, consult our TCPA compliance guide.
