If you've ever wanted to reach every household in a specific neighborhood — without buying a mailing list, managing a database, or printing names and addresses on each piece — Every Door Direct Mail (EDDM) was built for exactly that.

It's one of the most accessible direct mail programs the USPS offers, and for local businesses, it can be one of the most cost-effective ways to build awareness in a defined geographic area. But like any marketing channel, it works best when you understand what it's designed to do — and what it isn't.

What Is EDDM?

Every Door Direct Mail is a USPS program that allows businesses to mail to every address on one or more postal carrier routes — without needing individual names or addresses. You select the routes you want to target, print your mail pieces to USPS size specifications, and deliver them to the post office for distribution.

USPS handles the delivery. You handle the design and production. The result is saturation coverage of a defined area — every residential and/or business address on the routes you select receives your piece.

How EDDM Routing Works

USPS carrier routes are the geographic zones assigned to individual mail carriers. Each route covers a defined set of addresses — typically several hundred to a few thousand delivery points, depending on the area.

The USPS provides a free online mapping tool (the EDDM Online Tool at usps.com) that allows you to browse carrier routes by zip code, view household counts, and select the routes you want to include in your campaign. You can filter by household type (residential only, businesses only, or both), which helps focus your delivery on the audience most relevant to your offer.

Once your routes are selected, you'll know exactly how many pieces to print — one per delivery point on each route.

Who EDDM Is Right For

EDDM performs best for businesses whose customer base is defined by geography rather than demographics. Strong use cases include:

• Restaurants and food service — you're reaching everyone within delivery or drive distance

• Home services — HVAC, landscaping, plumbing, cleaning services that serve specific neighborhoods

• Retail and service businesses with a defined trade area

• Real estate professionals targeting specific neighborhoods

• Healthcare providers — dental, optometry, urgent care — marketing to a local area

• Grand openings and location launches where awareness within a radius is the goal

EDDM is less well-suited for businesses where the ideal customer has specific demographic or behavioral characteristics that aren't correlated with geography — in those cases, a targeted mailing list with carrier route selection will usually outperform pure saturation coverage.

EDDM vs. Targeted Mailing List: Which Is Right for You?

The choice between EDDM and a targeted list comes down to one question: do you know exactly who your customer is, or do you know where they live?

Many businesses use both: EDDM for broad local awareness campaigns (grand openings, seasonal promotions), and targeted lists for higher-value or more personalized outreach (customer reactivation, referral programs, premium service offers).

What Makes a Good EDDM Piece

EDDM has specific size requirements that differ from standard postcards — pieces must be larger than a standard postcard but within USPS flat-size specifications. Common formats include oversized postcards (6.5" x 9" or larger) and folded self-mailers. Your print partner can guide you on which sizes qualify.

Beyond specs, design matters enormously. Because EDDM reaches everyone on a route — not a pre-qualified audience — your piece needs to work hard to earn attention and communicate quickly. Best practices:

• Lead with a clear, specific offer or reason to act — not just brand awareness

• Make the headline readable in under three seconds

• Include a strong call to action with a simple response mechanism — QR code, phone number, or URL

• Use imagery that reflects your business and resonates with a neighborhood audience

• Include your physical address and service area so recipients know you're local

Print quality also signals business quality. An EDDM piece is often the first impression a potential customer has of your brand — a professionally designed, well-printed piece communicates credibility before a single word is read.

How to Get Started

The basic steps for an EDDM campaign:

• Define your goal — awareness, offer redemption, foot traffic, or phone calls

• Select your routes using the USPS EDDM Online Tool at usps.com

• Determine your piece count based on route delivery points

• Design your mail piece to USPS flat-size specifications

• Print and prepare your mailing (bundling, facing slips, postage)

• Drop off at your local post office for carrier route distribution

The preparation and drop-off requirements are specific — your print partner can walk you through the bundling and documentation requirements to ensure your mailing is accepted without issue.
