A message delivery system includes a plurality of terminals and a server communicating the terminals. Each of the terminals includes a message creation function unit creating a message for any member of a registered group, and a message delivery request function unit designating any location as a designated location and requesting a server to deliver the message to a member of the registered group entering the designated location. The server includes an entry monitoring function unit monitoring if a member of the registered group has entered the designated location, and a message delivery function unit delivering the message to a member of the registered group first entering the designated location and, if the first entering member refuses to accept the message, delivering the message to another member of the group next entering the designated area.
