Narrative:

Our company released our flight into known severe icing conditions without letting the crew know about the SIGMET that came out. Company releases all aircraft and send WX to crews. Callback conversation with reporter revealed the following: reporter states SIGMET came in about 15 minutes after WX brief by dispatch. Somehow no one thought to notify this crew who were already in the aircraft. Fortunately they arrived at destination before encountering severe WX. Sat on the ground 4 hours. Dispatch assumed crew knew of SIGMET, although no one could explain how that was possible.
