An inmate communication system is configured to manage the sending and receiving of messages on a messaging service between an inmate incarcerated in a correctional institution and other inmates, or between the inmate and a contact located outside of the facility. Example messaging services include SMS and MMS. Inmates are provided access to a messaging terminal. The inmates interact with the messaging terminal to compose messages for transmission and view received message transmissions. The message communications of the inmates and contacts are analyzed prior to transmission to the recipient. Message contents are analyzed for flagged key-words and flagged sender/recipients. Flagged messages may be placed in an approval queue prior to their delivery for approval or rejection.
