1. A method comprising:
receiving returned items from a carrier, each of said returned items having been included in a respective one of a plurality of shipping campaigns and having been determined by the carrier to be undeliverable;
after said receiving, determining for each of said returned items at least one of (a) a respective shipping campaign to which said each item belonged, and (b) a reason why said each returned item was determined to be undeliverable; and
selecting a course of action based on at least one of said determined respective shipping campaign and said determined reason,
wherein the carrier comprises a postal authority, the items comprise mailpieces and the shipping campaigns comprise mailings,
further comprising:
entering said determined reason in a database; and
reading information from said each returned mailpiece to determine said reason.
2. The method according to claim 1, further comprising:
scanning said each returned mailpiece to generate an image, said scanning performed at a first location;
transmitting said image to a second location that is remote from said first location; and
reading information from said image at said second location to determine said reason.
