Put your offer in every mailbox in the neighborhoods you choose — no mailing list, no permit, and flat $0.247-per-piece postage. We design, print, bundle, and handle every piece of USPS paperwork, for campaigns anywhere in the country.
Quick Answer
Every Door Direct Mail® (EDDM) is a USPS program that delivers your printed postcard, menu, or flyer to every address on the mail carrier routes you choose — no mailing list required, at the lowest postage rate USPS sells ($0.247 per piece at Retail). Catdi Printing designs, prints, bundles, and prepares your EDDM mailing to USPS specifications for businesses nationwide.
Every Door Direct Mail is the USPS program built for one job: putting a physical piece in every mailbox in a neighborhood without the cost and complexity of a mailing list. Instead of addressing each piece to a name, your mailer carries a simple "Local Postal Customer" block, and the letter carrier delivers one to every active address on the carrier routes you select.
Because there's no list to process, USPS sells EDDM at its lowest available postage — a flat $0.247 per piece whether you mail a 6.5" × 9" postcard or a 12" × 15" poster-size flat. There's no permit to buy, no annual fee, and you can send 200 to 5,000 pieces per ZIP code per day at the Retail level. For bigger or heavier drops, we run mailings through our own Business Mail Entry Unit permit, so you never need one.
The trade-off is precision: EDDM mails to every door on a route — whole routes only. That makes it the cheapest possible coverage for businesses whose customers are defined by where they live, and the wrong tool when only one household in fifty fits your offer. (Our guide chapter on who should use EDDM gives you the honest fit test.)
Five steps — and we do the heavy lifting on all of them. You approve the artwork; we take it from there.
Using the free USPS mapping tool, we select the postal routes around your business — sortable by household income, age, and household size from U.S. Census data. No mailing list to buy, ever.
Use our design team or send your own artwork. We place the EDDM indicia and "Local Postal Customer" address block to USPS spec and size-check the piece before anything prints.
Postcards, menus, and flyers on heavy stocks with vivid color — most campaigns run 6.5" × 9", 6" × 11", or the big 8.5" × 11" that owns the mailbox.
Pieces are faced and banded in USPS-compliant bundles of 50–100 with facing slips, mailing statements, and Post Office listings — the part that trips up do-it-yourselfers.
Your carriers deliver the pieces with the day's mail to every active address on your routes — typically within 3–7 business days of acceptance.

Saturation postage is the cheapest in the USPS system because carriers deliver to every door in walk order with no list processing. EDDM hands that discount straight to you.
Less than half the $0.61 stamped-postcard rate — and the price doesn't change with size. An 8.5" × 11" mails for the same postage as a small card, so bigger pieces win the mailbox for pennies more in print.
Targeted campaigns pay per record for mailing data. EDDM's targeting is the route map itself — pick routes by household income, age, and household size, and the list cost line on your quote reads zero.
No algorithm, no opt-outs, no inbox filters. Every active address on the route physically receives your piece with the day's mail — the kind of reach digital ads can't guarantee at any price.
Postage is always a pass-through at Catdi Printing — you pay exactly what USPS charges, itemized on your quote, never a markup. See the full price breakdown in our direct mail cost guide or price your own routes with the free postage calculator.
EDDM only accepts USPS flats, and the most popular postcard size — 6" × 9" — fails by a quarter inch. Grab the corner, resize your piece, and watch it pass or fail the official rules live.
Qualifies for EDDM
This piece is a valid USPS flat (height 6.5" beats 6.125") and stays within the 15" × 12" × 0.75" maximums. It mails at the flat $0.247 EDDM Retail rate as long as it weighs 3.3 oz or less.
Remember the print panel: the EDDM indicia and "Local Postal Customer" block must sit on the top half of the address side.
Flat EDDM Retail postage per piece — the same whether it’s this size or the 12″ × 15″ max. Bigger prints cost more ink, never more postage.
