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