EDDM vs. Targeted Direct Mail

Two methods dominate local direct mail services in the Hudson Valley: Every Door Direct Mail (EDDM) and targeted direct mail. Both reach physical mailboxes, but they work differently, cost differently, and fit different campaign goals. This guide explains when to use each — and when to use both.

What Is the Difference Between EDDM and Targeted Direct Mail?

EDDM delivers your mail piece to every address on a USPS carrier route — no mailing list required. Targeted direct mail uses a purchased or house list filtered by demographics, geography, or behavior to reach a specific audience. EDDM costs less per piece ($0.35–$0.55 all-in) but offers only geographic targeting. Targeted mail costs more ($0.65–$0.90 all-in) but delivers higher response rates because you are reaching the right people, not just the right area.

What Is EDDM?

Every Door Direct Mail delivers your mail piece to every address on a USPS carrier route. No mailing list required. No names, no addresses — just a carrier route selection and a mail piece. USPS handles delivery to every residential and/or business address on the selected routes.

EDDM postage runs $0.22–$0.23 per piece — the lowest available USPS rate. There is no permit fee for Retail EDDM. You select routes using the USPS EDDM Online Tool, which provides demographic data (household income, age, size) pulled from U.S. Census records. Cornerstone handles the entire process — route selection, design, printing, PS Form 3587, bundling, and post office delivery.

What Is Targeted Direct Mail?

Targeted direct mail uses a purchased or house list filtered by specific criteria: geography, demographics, homeownership, income, purchase behavior, SIC code, or any combination of selects. You are mailing to a defined audience, not a geographic area.

All-in cost runs $0.65–$0.90 per piece for a standard postcard campaign — higher than EDDM because you are paying for the mailing list, address verification (CASS/DPV/NCOA), and more precise targeting. See our 2025 direct mail pricing guide for a full cost breakdown.

When EDDM Is the Right Choice

EDDM works best when geographic reach matters more than demographic precision:

• Restaurant openings — blanket surrounding neighborhoods with menus
• Home services companies — HVAC, roofing, landscaping entering a new service area
• Political campaigns — saturation mailing to precincts and districts
• Retail stores — drive foot traffic from nearby carrier routes
• Grand openings — maximum awareness in a defined radius

EDDM’s cost advantage is significant. At 5,000 pieces, an EDDM postcard campaign runs roughly half the cost of a targeted campaign. For businesses where every household is a potential customer, EDDM delivers the most impressions per dollar.

When Targeted Direct Mail Is the Right Choice

Targeted mail wins when you need to reach a specific audience:

• Real estate agents farming homeowners filtered by length of residence
• Healthcare providers running patient acquisition by age and geography
• Financial services targeting by income, homeownership, or net worth
• Nonprofits mailing to donor lists or lapsed-donor reactivation
• B2B campaigns targeting businesses by SIC code and employee count

The higher cost-per-piece is offset by higher response rates. A 3% response on a targeted list generates more leads per dollar than a 1% response on an EDDM saturation mailing — if the list targeting is accurate. List quality is everything.

Targeted campaigns also support USPS Informed Delivery coordination — adding a digital email preview of your piece to subscribers’ inboxes. Informed Delivery averages 63% email open rates and can boost response by 10–15%.

Format Restrictions: What You Can and Cannot Mail

EDDM and targeted mail have different format rules, and choosing the wrong format for your method can cost you money or disqualify your mailing.

EDDM format requirements:

• Minimum size: 6.125×11.5 inches (flat-size) OR 4.25×6 inches (letter-size with specific thickness)
• Maximum size: 12×15 inches
• Maximum weight: 3.3 oz (Retail EDDM)
• Must be flat or folded — no envelopes, no enclosed letters
• Every piece must be identical — no variable data, no personalization

The most common EDDM format is the oversized postcard (6.5×9 or 6.5×12). Self-mailers (folded, tabbed pieces) also qualify. Standard #10 letters in envelopes do not qualify for EDDM.

Targeted mail format flexibility:

• Postcards from 4×6 through 6×11 (letter-class rates)
• Letters in #10 or 6×9 envelopes
• Self-mailers with tab closures
• Catalogs and multi-page booklets
• Variable data printing — personalized name, offer, images per recipient
• Oversize flats up to 12×15 inches

This format flexibility is a significant advantage of targeted mail. If your campaign requires a personalized letter, a reply envelope, or variable imagery based on recipient data, targeted mail is your only option. EDDM is limited to one-size-fits-all pieces.

Tracking and Measurement Differences

How you measure results differs between the two methods, and this affects your ability to optimize future campaigns.

EDDM tracking is geographic. Since there is no addressed list, you cannot track individual recipients. You track by carrier route — which routes generated more calls, website visits, or store traffic. This is sufficient for many local businesses but limits your ability to do follow-up mailings to responsive recipients.

Targeted mail tracking is individual. With an addressed list, you can match responses back to specific records. You know which demographic segments responded, which ZIP codes performed, and which individuals need a follow-up mailing. This data makes every subsequent campaign more efficient.

For campaigns where ongoing optimization matters — where you plan to mail repeatedly and refine over time — targeted mail’s tracking capability justifies the higher per-piece cost. For one-time awareness campaigns, EDDM’s geographic tracking is typically sufficient.

Both methods benefit from dedicated tracking mechanisms: unique phone numbers, campaign-specific landing page URLs, QR codes, and offer codes. See our direct mail response rate guide for detailed tracking setup instructions.

Using Both Together

Many of our full-service direct mail campaigns combine both methods. A common strategy:

• EDDM for broad awareness — saturate carrier routes around your location
• Targeted mail for acquisition — mail to a filtered list of likely buyers in a wider geography

A restaurant might EDDM postcards to every household within 3 miles while simultaneously running a targeted mailing to households with $75K+ income within 10 miles. Different audiences, different messages, same campaign cycle.

A home services company might use EDDM to introduce themselves to a new service area (low cost, maximum reach), then switch to targeted mail for follow-up campaigns to homeowners who are most likely to need the service (higher cost, better response rate).

Cornerstone runs both EDDM and targeted direct mail from the same facility. We recommend the right approach based on your goals, budget, and target geography — and for many clients, the answer is both, deployed strategically across different campaign phases.

Cost-Per-Lead: The Number That Actually Matters

Per-piece cost is the wrong comparison metric. The right metric is cost per lead — what you actually pay for each response.

Here is a real-world comparison using Hudson Valley campaign data:

Metric	EDDM Campaign	Targeted Campaign
Pieces mailed	5,000	3,000
Cost per piece	$0.45	$0.78
Total cost	$2,250	$2,340
Response rate	1.2%	3.1%
Leads generated	60	93
Cost per lead	$37.50	$25.16

In this example, the targeted campaign cost roughly the same total budget but generated 55% more leads at a 33% lower cost per lead. The higher per-piece cost was more than offset by the higher response rate.

This does not mean targeted always wins on cost-per-lead. For businesses where the entire carrier route is the target audience — pizza shops, dry cleaners, real estate open houses — EDDM’s lower cost per piece wins because the response rate gap narrows when every household is a genuine prospect.

CRST Insider Tip

Most businesses assume EDDM is always cheaper — and on a per-piece basis, it is. But we have seen targeted campaigns outperform EDDM on cost-per-lead by 40–60% in industries where the customer base is narrow. A Dutchess County financial advisor we work with switched from EDDM to a targeted list filtered by income and homeownership — their response rate jumped from 0.8% to 3.2%, and their cost per qualified lead dropped from $85 to $34. The lesson: cheaper mail is not always cheaper marketing. Start with the audience, then choose the method.

Frequently Asked Questions

Is EDDM available for all areas in the Hudson Valley?

Yes. USPS carrier routes cover all of Ulster, Dutchess, and Orange County. Cornerstone can map routes and pull delivery point counts for any geographic target in the region — from dense urban routes in Kingston and Poughkeepsie to rural routes in Delaware and Sullivan counties.

Can I add Informed Delivery to an EDDM campaign?

No. USPS Informed Delivery requires an addressed mailing list — it matches mail pieces to subscriber accounts by name and address. Since EDDM uses no addressed list (pieces are addressed to “Local Postal Customer”), Informed Delivery cannot match records and is not available for EDDM campaigns.

What is the minimum for an EDDM mailing?

Each carrier route typically has 200–500 delivery points. Retail EDDM requires mailing the entire route — no partial routes. You can select as few or as many routes as you want, but each selected route must receive complete coverage.

Which method is better for a first-time direct mail campaign?

For businesses with no prior direct mail experience and no existing mailing list, EDDM is often the best starting point. It has lower cost, no list to build, and simpler logistics — making it a lower-risk way to test the channel. If the EDDM campaign produces results, you have validated that direct mail works for your business and can invest in targeted list building for subsequent campaigns. If you already have a customer database with physical addresses, starting with a targeted house list mailing makes more sense — you are reaching people who already know you, which produces the highest response rates of any direct mail approach.

Can I switch from EDDM to targeted mid-campaign?

Not mid-campaign — each mailing is committed to one method once production begins. But you can alternate between methods across multiple mailings. Many of our clients run EDDM for broad awareness mailings (quarterly) and targeted mail for customer retention and acquisition (monthly). The two methods complement each other when deployed as part of an integrated direct mail campaign strategy.
