An electronic mail tracking system having automatic zip code break marking capability. A series of optical sensors along the mail piece transport path of the tracking system track the progress of the mail pieces. A felt tip marker removably mounted to a solenoid is selectively extended and retracted to mark zip code breaks and the mail pieces are then transported to a stacker. The system provides high speed, reliable and low cost zip break marking and tracking of mail piece.
