USPS EDDM
Every Door Direct Mail, run like a campaign.
EDDM reaches every active delivery address on the USPS carrier routes you select without buying a mailing list — one of the lowest-cost ways to saturate the neighborhoods you want to serve. The catch: the route choice, the piece, and the tracking decide everything. That is the part we own.
Saturation is the cheapest way to reach every door — and the fastest way to pay for the wrong ones.
So the first honest question is not how to run EDDM. It is whether EDDM is the right instrument for your business at all.
EDDM fits when
- Your customers are concentrated in mappable neighborhoods.
- Your service applies to most households — moving, HVAC, roofing, plumbing.
- You want saturation presence in a specific area at low postage cost.
- You can handle a burst of calls in the weeks after the drop.
We will recommend something else when
- Your buyers are a narrow segment better reached by a targeted list.
- Your service area is too spread out for route saturation to pay.
- The underwriting math needs a higher-value offer first.
- Your capacity is already full — more calls would hurt, not help.
What USPS requires of the piece
An EDDM piece has to be the right object before it can be a good advertisement.
Flat size
EDDM moves flats, not letters. A piece has to be big enough to qualify and small enough to carry.
- Qualifies as a flat by exceeding at least one of
- 10.5 in long · 6.125 in high · 0.25 in thick
- Maximum
- 15 × 12 × 0.75 in
- Minimum
- 3.5 in high · 0.007 in thick
- Maximum weight

Sources: the USPS Every Door Direct Mail pages, the USPS retail and BMEU facing-slip sheets, and the USPS EDDM quick-reference guide, read on 2026‑08‑19. The quick-reference carries a 2012 copyright, so we treat its dimensional and indicia detail as needing re-confirmation against the Domestic Mail Manual in force on your order date. We do not publish postage rates here — they change with USPS price updates, and we quote yours from a live check rather than from this page.
How we run it
Four steps from map to measured response.
- 01
Route selection with you
EDDM works by USPS carrier route, not by mailing list. We map routes against your service area, the neighborhoods you actually want to work in, and the drive time your crews can support.
- 02
A compliant, response-built piece
EDDM has specific size and format requirements. We design pieces that meet USPS specs and still earn attention — offer first, proof second, next step obvious.
- 03
Printing and USPS entry
We coordinate production and postal entry paperwork, and collect documentation of the mailing for your campaign record.
- 04
Tracking the response
Dedicated phone numbers, QR codes, and landing pages tell us which routes responded — so the second mailing is smarter than the first.
USPS rules, rates, and size requirements change periodically. We verify current requirements against USPS sources when planning your campaign rather than quoting stale numbers here.
Start here
Ask us whether EDDM fits your service area.
Send us the ZIPs you serve. We will come back with the routes worth saturating, the ones worth skipping, and why.
The campaign plan is free and carries no obligation. We ask who you are, your trade, your service area, a budget range, and how to reach you — and if the math doesn’t work in your market, we say so.
