Compliance considerations

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices:

  1. Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications.
  2. Only communicate during an end-user’s daytime hours unless it is urgent.
  3. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language.
  4. Do not contact end-users on do-not-call or do-not-disturb registries.
