Key points
- EDDM delivers one mailpiece to every address on the postal routes you pick. You cannot add names or skip addresses.
- EDDM Retail mailings are 200 to 5,000 pieces per day per ZIP Code, on large flat-size pieces weighing no more than 3.3 ounces.
- A targeted list goes only to people who match a reason to buy, and each card can be addressed and tracked on its own.
- Pick EDDM when nearly every household nearby could be a customer. Pick a list when only some of them could.
Every Door Direct Mail (EDDM) is a USPS service that delivers your mailpiece to every address on the mail carrier routes you choose. You do not need a mailing list, and you cannot use one: every piece is addressed to "Postal Customer". Targeted direct mail is the opposite. You start with a list of specific people or addresses and mail only to them. EDDM suits a business that almost any nearby household could use. A targeted list suits a business whose customers have something specific in common, such as a new roof, a new license or a new company.
How does EDDM work?
USPS describes the steps on its Every Door Direct Mail page. In short:
- Pick routes. In the EDDM Online Tool you search by address, city or ZIP Code and select carrier routes on a map. The tool shows counts for each route.
- Design a piece that meets the EDDM size and weight rules (below).
- Print it with the EDDM Retail postage marking (the "indicia") and the address "Postal Customer".
- Bundle the pieces in stacks of 50 to 100 and put a facing slip, with the piece count written on it, on top of each bundle.
- Pay online or at the counter, then take the bundles and the postage statement (PS Form 3587) to the Post Office that delivers those routes.
The detailed rules are in the Domestic Mail Manual (DMM), the USPS rulebook. Mailings must be entered at the Post Office that serves the routes, or shipped to that Post Office by Priority Mail. Pieces must be separated by route and bundled in groups of 50 to 100.
What are the USPS rules for EDDM Retail?
EDDM Retail is the version meant for small businesses. USPS says it needs no special mailing permit, only a USPS.com account. A second version, EDDM BMEU, is for large-volume mailers who pay with a bulk mailing permit and drop mail at a larger USPS facility.
| Rule | What USPS requires |
|---|---|
| Mail class | USPS Marketing Mail flats. EDDM is not First-Class Mail. |
| Minimum size | Must be more than 10.5 inches long, or more than 6.125 inches high, or more than 0.25 inch thick. |
| Maximum size | The general flat limits: 15 inches long, 12 inches high, 0.75 inch thick. |
| Weight | No more than 3.3 ounces per piece. |
| Quantity | At least 200 pieces, and up to 5,000 pieces per day per 5-digit ZIP Code. |
| Addressing | A simplified address such as "Postal Customer". No names, no street addresses. |
| Coverage | Complete distribution to the active deliveries on each route you choose. |
| Preparation | Bundles of 50 to 100 with a facing slip on each. |
The size, weight and quantity rules come from DMM section 143, and the flat maximums from DMM section 101.2. The addressing rule is in DMM section 602.3.2. It says the simplified format is for mail where complete distribution is intended to all active deliveries on a route, and that only the listed wordings may be used. "Postal Customer" is the standard one. "Residential Customer" and "PO Boxholder" are among the allowed variants.
How does targeted direct mail work?
With targeted mail you choose the people first. The list might be your own customers, or it might come from records that show a reason to buy: a building permit, a new professional license, a newly registered company. Each piece carries a real name and address, so it can go by First-Class Mail in a standard postcard size, and it can be sent in any quantity, including a few dozen at a time.
Because each card goes to one known recipient, each card can be different. It can use the person's name, mention the reason you are writing, and carry its own QR code (a square barcode a phone camera can read) so you can see which recipient responded.
EDDM vs. a targeted list, side by side
| EDDM Retail | Targeted list | |
|---|---|---|
| Who gets it | Every active address on the routes you pick | Only the people on your list |
| Addressed to | "Postal Customer" | A named person or business |
| Smallest mailing | 200 pieces | One piece |
| Piece size | Large flats only | Standard postcard sizes |
| Mail class | USPS Marketing Mail | Usually First-Class Mail |
| Who does the work | You print, bundle and drop off, or pay a printer to | Usually a mail service prints and mails |
| Personalization | None. Every piece is identical. | Name, offer and QR code can differ per card |
| Tracking | By mailing: one code or phone number for all | By recipient, if each card has its own code |
| Removing people | You cannot skip an address on a route | You can remove anyone, including opt-outs |
We have left postage out of the table on purpose. USPS prices change, so check the current price list. Postage is also only part of the cost: printing, the list and your time count too. Compare the total cost for each customer you win, not the cost of each piece. Our direct mail ROI calculator does that math.
When does EDDM fit?
- Nearly every household near you could buy: a restaurant, a dry cleaner, a dentist, a new store opening.
- Your offer is the same for everyone and does not depend on who the reader is.
- You want to cover whole neighborhoods at least 200 pieces at a time.
- You are comfortable printing large pieces, bundling them and taking them to the Post Office, or paying a printer to do it.
When does a targeted list fit?
- Only some households or businesses can use what you sell. A roofer needs homes with old roofs. A commercial insurance agent needs new businesses.
- Timing matters. A permit or a filing tells you something just changed.
- You are in a licensed industry and need each card to carry specific wording, or you need to honor do-not-mail requests.
- You want to know which recipients responded, not just how many.
- You want to start small and mail a steady number of cards each week.
Many businesses use both: EDDM once or twice a year for general awareness, and a targeted list every month for the people most likely to need them now. Whichever you choose, measure it. Response varies a great deal by offer, list and season, so the only response rate that matters is your own.
PostalNest is the targeted kind. Its data sources are built from public records such as city building permits, state professional license records and federal trucking registrations. You design a card, and each one is printed with its own QR code and mailed by First-Class Mail.
Common questions
Do I need a mailing list for EDDM?
No. EDDM pieces are addressed to "Postal Customer" and delivered to every active address on the carrier routes you select, so there is no list of names or addresses.
How many pieces can I send with EDDM Retail?
At least 200 pieces per mailing, and up to 5,000 pieces per day per 5-digit ZIP Code.
Can I send a regular postcard with EDDM?
Only if it meets the flat-size rule. An EDDM Retail piece must be more than 10.5 inches long, or more than 6.125 inches high, or more than 0.25 inch thick, and weigh no more than 3.3 ounces. A 6 x 9 inch card does not qualify.
Can I skip certain addresses with EDDM?
No. The simplified "Postal Customer" address is for complete distribution to the active deliveries on a route. If you need to leave people out, use an addressed mailing list instead.
Is EDDM First-Class Mail?
No. USPS classes EDDM pieces as USPS Marketing Mail flats.
