A system and method for delivering automated pre-recorded messages to intended recipients is disclosed. An automated call controller places phone calls to intended recipients and plays a pre-recorded message for the recipient after the call is answered. The automated call controller accesses phone numbers for intended recipients from a database and automatically dials the accessed phone numbers. The automated call controller monitors parameters associated with the telephone call. A message delivery decision model analyzes these monitored parameters, and any other parameters input to the decision model, and, based on the analysis of the parameters, optimizes the delivery of the pre-recorded message by the call controller. Results from the completed phone call are stored in the database and are utilized by the decision model to optimize the completion of future phone calls to that particular phone number.
