What is EDDM? Every Door Direct Mail, explained

EDDM stands for Every Door Direct Mail. It's a USPS program that lets you send mail to every address on a postal carrier route without buying a mailing list or knowing a single name.

That's the whole idea, and it's why it's cheaper than regular direct mail. You're not paying to target individuals. You're paying to blanket a neighborhood, and the carrier who already walks that route every day delivers your piece along with everything else.

How it actually works

You pick routes, not people.

USPS breaks every ZIP code into carrier routes — the loop one mail carrier walks or drives in a day, usually a few hundred addresses. Through the EDDM tool you choose which routes to hit, see roughly how many households and businesses are on each, and filter by things like average household income, average age, and household size.

Then you print your piece, bundle it the way USPS asks, drop it at the post office serving those routes, and pay. Every address on the routes you selected gets one.

No mailing list. That's the part that surprises people. You never buy or build a list, which removes both a cost and a data-privacy headache.

The two versions, and which one you want

This trips up almost everyone the first time.

EDDM Retail is the small-business version. No mailing permit required, you pay at the post office, and there's a daily cap on how many pieces you can send per ZIP code. For most local businesses this is the right one and the cap is never a problem.

EDDM BMEU is the higher-volume version, handled through a Business Mail Entry Unit. It requires a permit and more paperwork, but it lifts the daily limit and opens up more options. If you're mailing at a scale where the retail cap matters, you've probably already got someone handling this for you.

Which to pick: if you're a local business mailing a neighborhood or two, Retail. If you're mailing tens of thousands of pieces, BMEU — and at that point work with a mail house.

What EDDM costs

Three costs, and people usually only budget for one.

Postage. EDDM postage is priced per piece and is meaningfully cheaper than first-class mail, which is the entire appeal. Rates change, so check the current figure on the USPS EDDM page rather than trusting a number in a blog post — this one included.

Printing. Usually the bigger line item. Depends on size, paper weight, and quantity, and the per-piece cost drops sharply as volume rises.

Design. Either your time or someone else's. This is the cost most people skip and most regret, because the design does more to determine the result than the route selection does.

A rough way to think about it: postage plus printing together typically lands in the range of a few tens of cents per household. Mailing a thousand homes is a few hundred dollars, not a few thousand. That's the number to hold in your head before you go looking at exact rates.

Three numbers decide what a drop costs: how many households, what your printer charges per piece, and USPS postage. Two of those are yours. We'll handle the third.

The requirements that trip people up

EDDM has physical rules, and pieces get rejected at the counter for breaking them.

Size. Your piece has to be bigger than a standard postcard — EDDM requires flat-size mail, so the small postcards you might picture don't qualify. Print shops sell EDDM-specific sizes precisely because of this. If you're ordering from one, say it's for EDDM and the size problem solves itself.

Weight. There's a maximum weight per piece. Heavy card stock on a large format can push you over it, so check before you print several thousand.

The indicia. Your piece needs the correct postal marking and a simplified address block — something like "Local Postal Customer" rather than a name. Print shops handle this routinely; if you're doing it yourself, get the current template from USPS.

Bundling. Pieces have to arrive at the post office in bundles of a set size, with facing slips and completed paperwork. This is manual, tedious, and the most common reason a first-time EDDM drop takes longer than expected.

The safest move: use a printer who does EDDM regularly. They know the current specs, and the cost difference is small compared to a rejected run.

Who EDDM works for

Businesses with a geographic customer base. Restaurants, dentists, gyms, home services, salons, local retail. If your customers come from within a few miles, blanketing those miles makes sense.

New locations. Nothing announces an opening to a neighborhood faster.

Offers with broad appeal. Everyone eats. Everyone has a roof. The wider the appeal, the better untargeted mail performs.

Who it doesn't work for

Narrow or niche audiences. If one household in fifty is a plausible customer, you're paying to reach forty-nine who aren't. Targeted mail with a real list beats EDDM here, even at a higher cost per piece.

Businesses without a service area. If you sell nationally online, geography isn't your filter.

Anyone expecting immediate, trackable response. Mail works, but it works slower and less legibly than a click. Which brings us to the mistakes.

Common EDDM mistakes

No way to tell if it worked. The big one. Use a distinct phone number, a coupon code, a dedicated landing page — anything that separates mail response from everything else. Without it you'll have an opinion, not a result.

Mailing once. A single drop into a neighborhood is a coin flip. The businesses that get results from mail send to the same routes repeatedly, so the piece becomes familiar rather than novel.

Choosing routes by convenience. Nearest isn't the same as best. Use the demographic filters — a route half a mile further away with a better income match often outperforms.

Burying the offer. People decide in about a second, standing over a recycling bin. One offer, large, obvious. Not three.

Skipping the design. A cheap-looking piece signals a cheap business. The design is the message.

The version most people don't know about

There's a cheaper way to reach a neighborhood than mailing it yourself: share the piece.

In a co-op or shared mailer, several non-competing local businesses appear on one card sent to the same routes. You split the postage and printing, so the per-household cost drops well below what a solo EDDM drop costs. The tradeoff is that you're sharing attention with the other advertisers on the card.

For a small business testing whether mail works at all, that tradeoff is usually worth it — it's a much cheaper first experiment than committing to a full solo run.

That's one of the two ways our direct mail service works. We run a local co-op newsletter in the neighborhoods we serve, with one advertiser per category, and we run custom solo campaigns anywhere in the US through our USPS partnership. Whichever fits, we handle the specs, the bundling, and the paperwork.
