What Is USPS Marketing Mail?

USPS Marketing Mail is the official name for the mail class businesses use to send promotional material — postcards, catalogs, flyers, and similar pieces — to a specific list of addresses at a discounted, bulk postage rate. If the name doesn’t ring a bell but “bulk mail” or “standard mail” does, that’s because it’s the same thing under a different name: USPS rebranded Standard Mail as USPS Marketing Mail in 2016, specifically to make it clearer that the class exists for marketers sending promotional and advertising content, as opposed to personal or transactional correspondence.

USPS Marketing Mail vs. First-Class Mail

The tradeoff between these two mail classes comes down to speed versus cost. First-Class Mail is faster — typically delivered in 1 to 5 business days — but costs meaningfully more per piece, especially at volume. USPS Marketing Mail trades some of that speed for a substantially lower per-piece rate once you’re mailing in bulk, which is exactly why it’s the default choice for postcards, catalogs, and other promotional mail sent to a list rather than one letter at a time.

USPS Marketing Mail vs. EDDM: What’s the Real Difference?

This is the most common point of confusion, and it comes down to one thing: the list. USPS Marketing Mail requires you to have (and address) a specific list of recipients before you mail — a customer list, a purchased list, or any other targeted set of addresses. Every Door Direct Mail (EDDM), by contrast, needs no list at all; it mails to every address on a chosen carrier route instead of specific named recipients. If you’re trying to reach your own customers or a specific target audience, Marketing Mail is the right tool; if you’re trying to saturate a neighborhood regardless of who lives there, EDDM is. For a deeper look at EDDM specifically, see our guides on what EDDM is and EDDM postcard printing.

What Are “Flats” in USPS Marketing Mail?

Within Marketing Mail, USPS sorts pieces into three categories: letters, flats, and parcels. Letters are your standard postcards and small envelopes. Flats are the larger, rigid mailpieces — large envelopes, catalogs, and oversized pieces — that exceed standard letter-size limits, generally up to about 12″ x 15″ and 3/4″ thick. Parcels cover anything with more depth or bulk than a flat can handle. Most direct mail marketing (postcards, folded self-mailers, standard catalogs) falls into the letters or flats categories rather than parcels.

Minimum Requirements and Getting a Mailing Permit

USPS Marketing Mail isn’t something you can drop off one piece at a time. Every mailing needs at least 200 identical or nearly identical pieces, or a total weight of at least 50 pounds, to qualify for the discounted rate. You’ll also need a USPS mailing permit, which typically involves a one-time application fee plus an annual permit imprint fee (if you’re printing postage directly on the piece rather than using a stamp or meter) — real, ongoing costs that are part of why most businesses don’t set this up themselves for occasional mailings.

How Long Does USPS Marketing Mail Take to Deliver?

USPS doesn’t guarantee a specific delivery date for Marketing Mail, but the typical delivery window runs 3 to 10 business days, with most pieces arriving within 5 to 7 days. That’s noticeably slower than First-Class Mail, and it’s the direct tradeoff for the lower bulk postage rate — worth planning around if your mailing is tied to a specific date, like an event or a limited-time offer, since Marketing Mail simply doesn’t move with First-Class Mail’s priority.

How to Actually Use USPS Marketing Mail for Your Business

Given the permit process, the minimum quantity requirement, and the address-list preparation involved, most businesses don’t apply for their own USPS mailing permit for occasional campaigns — they go through a printer or mail house that already holds one. That gets you addressing, postal presort (which is what actually earns the bulk discount), and mailing handled as part of the print job, rather than a separate process you have to manage on top of design and printing.

A Note on Getting It Printed and Mailed

Greenerprinter handles USPS Marketing Mail campaigns directly — printing, addressing, postal presort, and postage are all included when you mail postcards, self-mailers, or catalogs to your own customer list, so there’s no separate permit or mailing setup on your end. Materials print on recycled, FSC-certified stock with soy-based inks. If you’re deciding between a targeted list mailing and EDDM’s route-based saturation coverage, our guide on which type of direct mail is best for your business walks through that decision in more depth.
