Every Door Direct Mail exists because it skips the two most expensive parts of a traditional direct mail campaign: buying a mailing list and getting a mailing permit. You pick routes by ZIP code on a USPS map, hand a bundle of postcards to a retail clerk, and every address on those routes gets one. No list, no permit, no minimum order beyond 200 pieces. That simplicity is also why the cost side gets glossed over — three separate line items stack per piece, and the one most people forget to check is the one USPS controls directly.

The Three Costs, Per Piece

An EDDM mailing's cost comes down to three components, each charged per piece and summed before multiplying by household count.

Cost Per Household = Printing + Shipping + Postage

Total Cost = Households × Cost Per Household

Printing and shipping are set by whichever vendor produces and delivers the pieces, and both vary by quote — paper stock, finish, quantity discounts, and whether shipping to the post office is bundled into the print price all move these numbers. Postage is the one figure USPS sets directly, and it is also the one most likely to be quoted from memory rather than checked.

Why the Postage Number Goes Stale

EDDM Retail postage was $0.260 per piece as of July 2026, up from $0.247 earlier in the same year — USPS reviews postage rates at least annually, sometimes more often, and a figure that was correct six months ago can already be wrong. On a 2,000-piece mailing, a $0.013 rate change most people would not think to double-check moves total cost by $26 — small at that volume, but the same gap scales linearly with every mailing after it if the stale number keeps getting reused.

The fix costs nothing: confirm the current rate at usps.com or with a retail associate close to the actual mailing date, rather than carrying forward whatever number was correct the last time a campaign ran.

Converting Routes to a Household Count

EDDM is sold by carrier route, not by an arbitrary number you choose, and route size varies by area more than most people expect. Dense urban and suburban routes commonly run 200 to 500 households; rural routes can run smaller or considerably larger depending on how development is distributed along the carrier's path. Averaging "households per route" across an unfamiliar area is a reasonable planning estimate, but the USPS EDDM route mapping tool shows the exact count for each specific route under consideration before any budget is finalized — worth checking directly rather than relying on an area-wide average for the final number.

A Worked Example

A 2,000-household mailing at $0.18 printing, $0.02 shipping, and the current $0.260 postage rate: cost per piece = 0.18 + 0.02 + 0.260 = $0.46. Total cost = 2,000 × 0.46 = $920. Postage alone accounts for $520 of that $920, or roughly 57% of total spend — a useful number to know when a print vendor is trying to win business on printing price alone, since postage is the majority cost and is not something any print vendor controls or discounts.

Volume Limits That Shape a Mailing Plan

EDDM Retail requires a minimum of 200 mailpieces per submission and caps at 5,000 pieces per day per ZIP code at the retail counter rate. A campaign larger than 5,000 pieces in a single ZIP code needs to either split across multiple days, spread across multiple ZIP codes, or move to a bulk mailing arrangement through a Business Mail Entry Unit — which carries its own separate size, weight, and permit rules distinct from EDDM Retail.

Frequently Asked Questions

Does EDDM postage cost more or less than a targeted mailing?

EDDM Retail postage typically sits below First-Class postage per piece, and requires no mailing list purchase or permit fee — the trade-off is that every address on the chosen routes receives the piece, with no ability to exclude specific households the way a targeted, addressed list allows.

Can I get an exact household count before committing to routes?

Yes — the USPS EDDM route mapping tool shows the precise household count for each individual route before you select it, rather than requiring an estimate from an area-wide average.

What happens if I need to mail more than 5,000 pieces?

Split the mailing across multiple days or multiple ZIP codes at the EDDM Retail counter, or move to a bulk mailing arrangement through a Business Mail Entry Unit, which allows larger volume but requires a permit and follows a different set of size and weight rules than EDDM Retail.

Is shipping to the post office always a separate cost?

Not always — many print vendors that specialize in EDDM bundle printing and delivery-to-post-office shipping into one quoted price per piece. Worth asking for as a single combined number when comparing vendor quotes, rather than assembling separate printing and shipping estimates from different sources.

Does the postage rate differ by mailpiece size?

EDDM Retail applies a flat per-piece rate regardless of size, as long as the piece falls within the required dimension range. A piece outside that range does not qualify for EDDM Retail at all, regardless of postage rate.
