Mail Classes & RatesUpdated 2026-07-24

A USPS class for advertising and promotional mail. Postage is lower than First-Class, but forwarding and returns work differently by default.

Definition reviewed 2026-07-24. This is a plain-English Plavidian reference; for USPS terms, the Domestic Mail Manual is the authority. For your own job, the final mail class, postage, and preparation are confirmed after list processing and production review.
