Patent US 11,509,617

A messaging system for relaying messages to groups of inmates located in one or more controlled-environment facilities. The system receives a message from a user and a recipient designation identifying those inmates designated for receiving the message. The system performs a content check of the message or requests administrator authorization of the message, and then packages the message in a format designated by the facility. The packaged message includes the message itself, and also recipient information and other delivery information. The message may be packaged uniquely according to facility specifications. At the facility, the received message is unpacked. Recipients are identified from the recipient designation in the message, and delivery methods are retrieved for each of the intended recipients. Delivery of the message is then carried out, at a time designated in the message, according to the retrieved delivery methods.
