Compliance considerations	Direct marketing messages are regulated under article 16 of the Wireless Application Service Providers’ Association (WASPA) Code of Conduct. Unless a consumer has expressly or implicitly requested or agreed otherwise, marketing messages should not be sent on: Sundays and public holidays; Saturdays before 9am and after 1pm; and all other days between the hours of 8pm and 8am the following day. 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.
