Twilio has introduced a new feature called Advanced Opt-Out Messaging Service, which allows developers to customize opt-in, opt-out, and help keywords for their messaging campaigns on a global basis. This feature provides granular control over compliance with regulations such as TCPA and CTIA guidelines, allowing developers to deliver a better customer experience while ensuring they remain in compliance of region-specific regulations. With Advanced Opt-Out, developers can configure custom compliance flows across their Messaging Service, including opt-in, opt-out, help, and overrides, and gain visibility into the health of their campaigns with improved tracking capabilities.
