Opt-in and opt-out compliance

MessageBird takes compliance with regulations seriously and monitors standard OPT-IN and OPT-OUT keywords to ensure compliance. If an opt-out request is received, MessageBird will process it and block future communications between the Sender and the Receiver (opt-out number) until this same Receiver (the end-user) opts in again by sending the appropriate keyword.

To further support customers in ensuring compliance, MessageBird offers the option to set up personalized opt-out acknowledgment, non-standard opt-out words (for example, in different languages), as well as opted-out number tracking. This can be done using Flows.
