What is the minimum quantity of pieces required for marketing mail?

The correct minimum quantity of pieces required for marketing mail is 200 pieces. This requirement is based on the USPS regulations that are designed to ensure that mailings are of sufficient size to be processed efficiently. Marketing mail is intended for bulk mailing, often involving advertising or promotional materials sent to multiple addresses.

By setting a minimum quantity, the USPS can streamline its sorting and distribution processes, allowing for more economical handling of these types of mail. This bulk requirement also helps businesses achieve greater visibility and reach in their advertising efforts, taking advantage of the discounts offered for larger mailings. Thus, marketing mail must meet the threshold of 200 pieces to qualify for the specific rates and processing benefits associated with this class of mail.
