Abstract: A system is disclosed that sends, through one or more messaging modalities, an electronic message containing a system or user genera0ted unique identifier to at least one recipient on a system or user enabled and controlled list. The system receives a response electronic message containing the unique identifier and response data identified by a symbol. The program verifies the validity of the unique identifier and optionally that a sender of the response message is on the list. If the unique identifier is verified, the program correlates the message response data with the unique identifier and sends an additional message replicating the response data to the controlled list as a reply or update concerning the message. The program repeats the receiving, verifying, and sending to allow further updates on the message using the modality of communication.
