Price a do-it-yourself Every Door Direct Mail drop. Postage, printing, total, and cost per piece. Enter mailpieces directly or build the count from routes and homes per route. PostKnock doesn’t run EDDM drops; this is a planning tool for the one you run yourself.
Heads up: PostKnock does not offer EDDM. Every PostKnock postcard is addressed to a named recipient. That’s what lets us verify the address, honor your do-not-contact list, personalize the card, and hand your front desk a follow-up call. EDDM trades all of that for cheaper postage on anonymous “Postal Customer” mail. If that trade is right for you, this calculator prices the USPS retail EDDM drop you’d run yourself.
EDDM saturates entire USPS carrier routes. You mail to every address on each route you select.
USPS EDDM Retail caps you at 5,000 pieces per ZIP per day; larger drops use EDDM BMEU.
EDDM flats must be larger than a standard letter; 6×9 and 6×11 are the common saturation sizes.
Leave at 0 to estimate postage only. Self-printed EDDM flats typically run ~$0.05–$0.15 each at volume; a print shop may charge more.
Estimate only. Postage uses the current public USPS EDDM Retail rate of $0.26 per piece (the “every door” commercial flats rate). USPS rates change periodically and vary by entry method (Retail vs. BMEU): always confirm current pricing at usps.com before you budget. This tool does not include design, mail-prep bundling, or sales tax.
PostKnock does not offer EDDM, and we’ve decided not to build it. Every PostKnock postcard is addressed to a named recipient. That single decision is what lets us verify the address before it prints, honor your do-not-contact list, personalize the card to the person reading it, and hand your front desk a follow-up call with a name and number attached. EDDM gives all of that up in exchange for cheaper postage on anonymous “Postal Customer” mail.
EDDM also puts the work on you: design the flats, print them, sort into route bundles, fill out the paperwork, and drop them at the right Post Office. With a list of named recipients, PostKnock handles targeted list mailing end to end: design in the in-app Design Studio (4×6, 6×9, 6×11), import your CSV, pay per piece from your wallet, and our print partner produces and mails it. No bundling, no minimums, no contracts.
PostKnock’s all-in per-piece pricing (printing + First-Class postage) starts at $1.04 on the Free plan and $0.91 on Pro. That’s more per piece than raw EDDM postage, because it buys a different thing: printing, addressing, QR-code scan tracking, and the option to add a phone-call follow-up wave via the built-in Call Queue (Pro). If blanket coverage of a neighborhood is what you actually need, run the EDDM drop yourself. The calculator above will price it.

The EDDM Retail rate is a single flat per-piece rate regardless of postcard size, as long as the piece meets USPS flat dimensions. That’s why all three sizes share the same postage figure here. Rates are estimates; confirm the current figure on the USPS prices page before committing a budget.

USPS EDDM Retail postage is a single flat per-piece rate: currently about $0.26 per piece on the public price list, no matter which qualifying postcard size you mail. On top of postage you pay for printing (often ~$0.05–$0.15 each at volume if you self-print, more through a print shop). So an all-in EDDM piece commonly lands somewhere around $0.31–$0.45 depending on print quality and quantity. These are estimates; USPS rates change, so confirm the current figure at usps.com.
EDDM (Every Door Direct Mail) lets you saturate entire USPS carrier routes without buying a mailing list or printing individual addresses. Because USPS doesn’t have to sort to a specific name, the per-piece postage is lower than addressed mail. The trade-off: you mail every home on a route rather than only your ideal prospects, and you handle bundling and drop-off yourself. It’s a volume play, best for businesses targeting a whole neighborhood.
With EDDM Retail you can mail up to 5,000 pieces per ZIP code per day at the Post Office. Larger volumes use EDDM through a Business Mail Entry Unit (BMEU), which has no 5,000-piece cap but requires a permit and more mail-prep. This estimator uses the EDDM Retail per-piece rate; if your drop exceeds 5,000 per ZIP per day, check USPS for the BMEU process and current pricing.
No, and it isn’t something we plan to add. PostKnock mails to named recipient lists you import via CSV: addressing every card to a person is what lets us verify the address, honor your do-not-contact list, personalize the message, and hand your front desk a follow-up call. EDDM trades all of that for cheaper postage on anonymous “Postal Customer” mail. With PostKnock you design your postcard in the in-app Design Studio (4×6, 6×9, or 6×11), and we handle printing and First-Class mailing for a single per-piece price paid from your wallet, with QR-code scan tracking and an optional phone-call follow-up wave via the Call Queue on the Pro plan. Use this estimator to price a do-it-yourself USPS EDDM drop instead.
Design your postcard, import your list, and let PostKnock print and mail it. Pay per piece from your wallet. No monthly fee to start.
