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 $0.224 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.
EDDM is cheap on postage, but you do the work: design the flats, print them, sort into route bundles, fill out the paperwork, and drop them at the right Post Office. PostKnock runs EDDM-style saturation mailing the easy way — design in the in-app Design Studio (4×6, 6×9, 6×11), pay per piece from your wallet, and we handle printing and mailing. No bundling, no minimums, no contracts.
PostKnock’s all-in per-piece pricing (printing + First-Class postage) starts at $1.05 on the Free plan and $0.79 on Pro — higher per piece than raw EDDM postage, but it includes printing, addressing or saturation routing, QR-code scan tracking, and the option to add a phone-call follow-up wave via the built-in Call Queue (Pro). Pick the route that fits your time and budget.

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 usps.com before committing a budget.

USPS EDDM Retail postage is a single flat per-piece rate — currently about $0.224 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 $0.27–$0.40 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.
PostKnock offers EDDM-style saturation mailing without the manual bundling and Post Office trip. You design your postcard in the in-app Design Studio (4×6, 6×9, or 6×11), and PostKnock handles printing and mailing for a single per-piece price paid from your wallet. That all-in price is higher than raw EDDM postage because it includes printing and fulfillment — but you skip the prep work, get QR-code scan tracking, and can add a phone-call follow-up wave via the Call Queue on the Pro plan. Use this estimator to compare the do-it-yourself EDDM route against PostKnock’s done-for-you per-piece pricing.
Design your postcard, pick your area, and let PostKnock print and mail it. Pay per piece from your wallet. No credit card to start.
