 Azure Communication Services will detect the STOP message and block all further messages to the recipient. The delivery report will indicate a failed delivery with status message as “Sender blocked for given recipient.” The STOP, UNSTOP and START messages will be relayed back to you. Azure Communication Services encourages you to monitor and implement these opt-outs to ensure that no further message send attempts are made to recipients who have opted out of your communications.
