<p>A survey is placed into an envelope containing an address label and a tracking indicia, see figure 1 (105). The address label indicates an old address of the recipient. The envelope containing the survey is routed through a delivery system (130). The delivery system is configured to sense the tracking indicia as it passes through the elements of the delivery system thus tracking the movement of the envelope through the system. The envelope containing the survey is sent through the delivery system to the plant supporting the old address. The recipient, however, no longer resides at the old address and now resides at a new address. The envelope containing the survey is forwarded through the delivery system to the plant supporting the new address. Once the recipient receives and completes the survey, survey is sent to the system operator for analysis.</p> |
