If you maintain an address database and apply your own labels to a bulk mailing, then submit it without first cleansing the list, you will not be eligible for a presort or automated discount. Your mailing charge will be the single-piece, first-class rate—42 cents or more, depending on the weight of the piece.
Using updated mailing addresses will save you money not only through better postage rates, but also by ensuring that none of your mail pieces are returned for improper or incorrect addresses. Address corrections from the Postal Service can cost 70 cents per returned mail piece, plus additional postage in some instances. Call Bulk Mail at 384-3809 with questions or to make arrangements for address file cleansing.
