Presorting is defined as preparing your mailing so that it is sorted to the lowest level available for the type of mailing whether First Class, Standard or Non-Profit. In automating your mailing, a barcode is applied in the address area to assist in processing at the Post Office. Discounts off regular postage rates are applied to Presorted and Automated mailings. Copy2Copy uses the latest software technology to maximize any postage discounts for which your mailing may qualify.
