What is EDDM (Every Door Direct Mail) and Is It Right for Your Business?

Every Door Direct Mail — EDDM — is one of the most misunderstood programs in the direct mail industry. Businesses hear "$0.214 per piece" and immediately want to use it for everything. The reality is more nuanced: EDDM is an exceptional tool for the right situations, and a mediocre one for the wrong ones. This guide explains what EDDM actually is, how the USPS program works, and how to determine whether it's the right choice for your specific campaign objective.

The USPS EDDM Program Explained

Every Door Direct Mail is a United States Postal Service program that allows businesses to mail to every active delivery point on one or more carrier routes — without purchasing, cleaning, or managing a mailing list. Instead of addressing pieces to named individuals, EDDM pieces carry a generic delivery address ("Local Postal Customer") and are delivered to every residential and business address on the routes you select.

The current EDDM Retail postage rate is approximately $0.214 per piece — one of the lowest per-piece rates available for any mailing format. This rate is possible because EDDM pieces are presorted and bundled by carrier route, reducing USPS processing costs significantly compared to a standard Marketing Mail letter or postcard that needs to be individually sorted and routed.

The program comes in two varieties: EDDM Retail and EDDM BMEU. EDDM Retail is available to anyone — no postage permit required. You select your routes using the USPS online mapping tool, print your pieces, bundle them, and drop them at your local post office. The catch: EDDM Retail caps at 5,000 pieces per ZIP code per day, making it impractical for large campaigns. EDDM BMEU (Business Mail Entry Unit) is submitted through a licensed mail house like Dimaco and has no daily cap — making it the standard for volume campaigns.

When EDDM Beats Targeted Mail

EDDM wins clearly in three scenarios. First, geographic saturation — when you want to reach every household in a defined area regardless of demographics. A restaurant opening in a new location, an HVAC company offering seasonal tune-up specials to the surrounding neighborhood, or a school announcing open enrollment to all families within a certain radius are all situations where saturation is the goal and demographic filtering is irrelevant.

Second, list cost avoidance — when the cost of purchasing, cleaning, and managing a targeted list would represent a significant portion of your campaign budget, and you're not sure the targeting precision is worth the premium. For hyperlocal businesses with a clear geographic catchment area (dry cleaners, nail salons, pediatric dental practices), the people who live within walking distance are your entire market — EDDM reaches them all without list overhead.

Third, new market entry — when you're launching into a new area and don't have existing customer data to build a look-alike list from. EDDM gives you immediate saturation coverage while you begin building your local customer base.

When Targeted Mail Beats EDDM

Targeted mail outperforms EDDM whenever demographic precision materially improves response rates. If you're a wealth management firm targeting homeowners with investable assets above $500,000, EDDM is inefficient — most of the carrier route doesn't meet your qualification criteria, and you're paying print and postage for households who would never be prospects regardless of what you sent them.

Targeted mail is also essential when personalization is part of your strategy. EDDM pieces are identical — no names, no personalized offers, no variable data. If you want to address recipients by name, reference their vehicle ownership, or print a personalized offer based on their account history, you need a targeted list with variable data printing — which EDDM cannot support by definition.

Finally, targeted mail is necessary when you need to exclude certain addresses — existing customers, competitors, people who have opted out, or businesses in a residential campaign. EDDM delivers to every delivery point on every selected route with no suppression capability.

How to Select Carrier Routes with the USPS EDDM Tool

The USPS provides a free online mapping tool at usps.com that lets you visualize carrier routes by ZIP code. Each route shows total delivery count, average household income, average household size, and age data from the American Community Survey. You select routes by clicking them on the interactive map, and the tool calculates your total piece count and estimated postage.

For most DFW businesses, a practical EDDM targeting exercise looks like this: enter the ZIP codes within a 2–5 mile radius of your location, review the route demographics to identify the highest-concentration residential routes, select the routes that cover your target area, and review the total piece count against your budget. Dimaco can handle this route selection process on your behalf and provide a route summary report showing total households, demographics, and estimated delivery timing.

EDDM Design Specifications

EDDM pieces must meet specific USPS dimensional requirements. The minimum size is 10.5 inches long or 6.125 inches tall — pieces smaller than this do not qualify. Maximum size is 12×15 inches. The EDDM Retail indicia (a specific USPS-approved postage imprint) must appear in the upper-right corner of the address side. The delivery address line must read "Local Postal Customer" or "Postal Customer." Your return address goes in the upper-left corner.

For print quality, files should be submitted as PDFs at 300 DPI (for photos) and 600 DPI (for text and line art), in CMYK color mode, with 0.125-inch bleed extending beyond the trim line on all sides. Dimaco's prepress team reviews every EDDM file for spec compliance before releasing to print — catching bleed, resolution, and color mode issues before they result in a reprint.
