Every Door Direct Mail (EDDM) Done Right

Every Door Direct Mail (EDDM) is a United States Postal Service program introduced to help small and mid-size businesses advertise locally without the cost and complexity of a targeted mailing list. Rather than buying, cleaning, and managing a list of individual names and addresses, EDDM mailers simply choose which carrier routes they want to saturate — and the USPS delivers to every active delivery point on those routes.

As of the current USPS rate schedule, EDDM Retail postage starts at approximately $0.214 per piece, making it one of the lowest per-piece postage rates available for any mailing format. There are no list rental fees, no per-record data charges, and no NCOA processing costs because you are not targeting individuals by name. The tradeoff — which we explain in the section below — is that you cannot suppress specific addresses, exclude competitors, or personalize by recipient. If saturation is your goal, EDDM is nearly always the most cost-efficient path.

The EDDM program has two delivery models: EDDM Retail and EDDM BMEU (Business Mail Entry Unit). EDDM Retail is available to any mailer — you do not need a postage meter or a mailing permit, and you can submit your mailing directly at your local post office. However, EDDM Retail caps you at 5,000 pieces per ZIP code per day. EDDM BMEU is designed for volume mailers submitting at a Business Mail Entry Unit and supports larger quantities without the daily cap. Dimaco handles both models and manages the postal paperwork, bundle preparation, and delivery to the originating post office on your behalf.

The physical format requirements for EDDM are distinct from standard postcard mailings. EDDM pieces must be larger than 10.5 inches long or 6.125 inches tall — the program was specifically designed to prevent thin, easily-ignored pieces. The maximum size is 12 inches by 15 inches. Every piece must carry the EDDM Retail indicia in the upper-right corner, a "Local Postal Customer" delivery address in the center, and a return address. Dimaco's production team verifies all of these specs before any job goes to press.

The USPS provides a free online EDDM mapping tool at usps.com that allows any mailer to search routes by ZIP code, view demographic data for each route, and estimate delivery counts. Routes are displayed on an interactive map, color-coded by household count, and each route shows summary data including total deliveries, average household income, average household size, and average age. This data comes from the American Community Survey and is updated periodically.

A basic route selection workflow starts with entering your target ZIP codes. The tool returns all carrier routes within those ZIPs, each with a route identifier (e.g., "C001" for City route 1). You select routes by clicking them on the map or checking them in the list view. The tool tallies your total delivery count and calculates estimated postage at the current EDDM rate. For EDDM Retail, you are limited to 5,000 pieces per ZIP per day, so large campaigns may need to be staged across multiple days or submitted as EDDM BMEU through a mail house like Dimaco.

Demographic filtering is available in the tool, but it is limited. You can see aggregate route-level income, age, and household size data — but you cannot filter to only deliver to households above a certain income, or exclude business addresses (P.O. boxes and businesses are automatically excluded from EDDM residential delivery, but mixed commercial-residential routes will include all delivery points). For campaigns where demographic targeting is important, consider a hybrid approach: EDDM for high-density residential areas and a targeted purchased list for specific demographic profiles in lower-density zones.

Dimaco can handle the route selection entirely on your behalf. We use the USPS EDDM tool alongside our own route-level data to recommend routes that match your stated objectives — whether that is maximum reach per dollar, proximity to a specific address, or demographic alignment. We provide a route summary report before production so you know exactly how many households you are reaching and what you are paying per route.

EDDM route selection is a geographic decision, not a demographic one, and doing it well comes down to understanding what carrier routes represent and how to layer them against your campaign goal. A carrier route is the daily delivery area assigned to a single USPS mail carrier — typically 300 to 500 active delivery points. Routes are identified by a code (such as C001 for a city route or R002 for a rural route) and can be selected individually or grouped to form a contiguous coverage area. Because you are buying geography, the most important inputs are your service radius, the density of households in that radius, and whether those households match your customer profile at a neighborhood level.

A practical selection process starts with your business address or target ZIP codes. From there, the USPS EDDM mapping tool displays every carrier route in the area along with route-level demographic summaries — average household income, household size, median age, and total delivery count. You select routes that fall within your desired drive-time or service radius and tally the total delivery count, which directly determines your print quantity and postage. The key is to avoid over-saturating: a common mistake is selecting every route in a ZIP code when only a subset falls within a realistic customer radius, which wastes postage on households too far away to convert.

Dimaco handles route selection for clients who would rather not navigate the USPS tool themselves. We pull route summaries, compare delivery counts against your budget, and provide a route map and household count for approval before production. For campaigns that need both saturation and precision — for example, a home services company that wants full coverage near recent job sites but also a targeted list in adjacent demographics — we can blend EDDM with a targeted purchased list in a single coordinated drop.

EDDM is built for businesses whose customers are defined by proximity rather than by a specific demographic profile. The clearest fit is local consumer businesses with a geographic service area: restaurants, retail stores, gyms, dental and medical practices, and home service companies. A new restaurant announcing its grand opening does not need to filter by income — it needs every household within a few miles to know it exists. EDDM delivers that awareness at a cost per thousand impressions that digital channels and targeted mail cannot match for pure saturation.

Real estate agents are a natural EDDM audience. Neighborhood farming — sending postcards to every home in a target area on a recurring schedule — builds the name recognition that drives listing calls over time. Just Listed and Just Sold cards reinforce local expertise and keep the agent top-of-mind. Because real estate farming depends on frequency and coverage rather than individual targeting, EDDM's low per-piece cost makes a sustained multi-drop schedule affordable in a way that list-based mail rarely is.

Home service companies — HVAC, roofing, plumbing, landscaping, pest control — benefit from EDDM's "we're working in your neighborhood" positioning. A saturation drop to routes adjacent to an active job site leverages proximity and social proof: neighbors see the truck, then receive a card reinforcing the company's local presence. Seasonal EDDM campaigns (HVAC before summer and winter, landscaping in spring, pest control at the start of warm weather) create a predictable cadence that builds recall over multiple seasons. Churches, schools, and nonprofits doing community outreach also fit the EDDM model well, since their message is relevant to an entire area rather than a filtered subset. For businesses that need demographic precision, personalization, or individual response tracking, targeted list-based mail remains the better tool — and Dimaco offers both under one roof.
