USPS promotions are temporary incentives designed to encourage mailers to use mail in more engaging, innovative, or strategic ways. Essentially, the Postal Service offers postage discounts when your mailpieces meet specific criteria, whether it’s seasonal consistency, interactive features, or catalog formats, and you register for the promotion before you mail.
To qualify, your mail typically needs to be eligible classes like First‑Class Mail® and Marketing Mail® letters or flats. Many promotions also allow nonprofit Marketing Mail. Before your mailing, you must register through the USPS Business Customer Gateway, upload details of your campaign, and confirm eligibility. Deadlines matter: late registration or missing required documentation often disqualifies the discount. Planning ahead, especially around registration windows and the promotion period, is critical for success.
