Direct Mail Marketing: How to Run a Campaign That Gets Responses
When to use Every Door Direct Mail and when to mail your own list, the offer that makes people respond, how to handle opt-outs and the math that tells you if the campaign paid off.
Direct mail marketing is advertising sent to a specific household or person by mail, asking for a response you can count: a call, a booking, a purchase. Direct mail marketing works when it reaches the right mailbox with one offer, a deadline and a way to respond that you can track.
In late October 2026, we looked at what Google shows in the US for this topic and asked ChatGPT, Perplexity and Gemini whether direct mail still works and whether it is legal. Most of the top results come from printers and mailing companies selling the service. Here are the steps, the rules and the math to measure it yourself.
Types, EDDM, steps, tracking, opt-outs and examples: this guide is part of our traditional marketing section.

What Is Direct Mail Marketing? Types and When It Works
It is marketing that reaches chosen people at their mailing address, without a middleman, to get an immediate and measurable response.
What is direct mail marketing, in one sentence: printed pieces sent to households or businesses you pick, by address or by mail route, with an offer and a way to reply. What defines direct mail is not the paper but the fact that every response can be traced back to the campaign.
What it is not: it is not mass advertising like a billboard or a radio spot, which reaches everyone passing by without asking for a specific reply. It is not junk mail by default either; it only becomes junk when it goes to the wrong people.
| Format | How it reaches people | Works best for |
|---|---|---|
| Direct mail postcards | Short offer, no envelope to open | Promotions, events, reminders |
| Letters | Personalized, in an envelope | Existing customers, B2B, explaining a service |
| Catalogs and brochures | Several products or details | Retail, services with options |
| Every Door Direct Mail | Every address on chosen routes, no names | Local businesses looking for new customers |
Postcard marketing is the easiest place to start: one side for the hook, the other for the offer and the code.
Every Door Direct Mail or a Targeted Direct Mail List?
Use Every Door Direct Mail to blanket a neighborhood without a list; use a targeted direct mail list when you know exactly who should get it.
| Every Door Direct Mail | Targeted direct mail | |
|---|---|---|
| Who gets it | Every address on the routes you pick | Specific people on your list |
| Needs a list | No | Yes: your customers or a rented list |
| Typical piece | Postcard, menu, flyer | Personalized letter, postcard, catalog |
| Best for | Restaurants, gyms, real estate, home services | Clinics, studios, stores with repeat buyers |
| Hardest part | Volume and waste | Keeping the list clean |
What is EDDM?
EDDM is the US Postal Service's Every Door Direct Mail program: it delivers your mailer to every address on the carrier routes you choose, with no names or mailing list. According to the USPS EDDM page, the Retail option needs no special permit and takes at least 200 and up to 5,000 pieces per day per ZIP Code. The BMEU option, for large mailers, has no volume limit and requires a bulk mailing permit.
How Much Does EDDM Cost? Postage, Printing and a Sample Budget
Postage is the fixed part. According to USPS Notice 123, effective October 4, 2026, EDDM Retail costs $0.260 per piece for flats up to 3.3 ounces. The USPS EDDM page lists the BMEU option for big mailers at $0.259 per piece, a tenth of a cent less, so the real difference between the two is the permit, not the price. Printing is the part that moves with size, paper and quantity, so ask two or three printers for the same spec.
Here is a made-up budget for 5,000 postcards, with an invented print quote of $0.16 each:
| Item | Cost |
|---|---|
| Postage, 5,000 x $0.260 | $1,300 |
| Printing, 5,000 x $0.16 (invented quote) | $800 |
| Total | $2,100 |
| Per piece | $0.42 |
Postage is about 62% of that bill, so a cheaper print run saves less than reaching the wrong routes costs you. Divide the total by your responses: at 40 responses, each one costs $52.50.
Test before you commit. An EDDM Retail mailing needs at least 200 pieces, so a 1,000-piece test runs about $420 at the same unit cost, although a short print run costs a bit more per card. It tells you your real cost per response before you spend $2,100.
EDDM Postcard Size: What Fits the Rules
EDDM Retail only takes flat-size pieces, and some of the most common postcards are not. The USPS Quick Service Guide for EDDM-Retail says a piece needs at least one dimension greater than 10 1/2 inches long, 6 1/8 inches high or 1/4 inch thick. It must weigh 3.3 ounces or less and stay between 5 x 3.5 inches and 15 x 12 inches.
| Size (inches) | Flat for EDDM Retail? | Why |
|---|---|---|
| 4 x 6 | No | Neither side passes the limits |
| 6 x 9 | No | Height 6 is under 6 1/8, length 9 is under 10 1/2 |
| 6.5 x 9 | Yes | Height 6.5 is over 6 1/8 |
| 6 x 11 | Yes | Length 11 is over 10 1/2 |
| 8.5 x 11 | Yes | Both sides pass |
The shortcut: if the short side of your card is 6 1/8 inches or less, the long side has to pass 10 1/2 inches. So if your printer quotes a 6 x 9 card, ask for 6.5 x 9 instead. Leave room on the address side for the EDDM indicia, which USPS says must be larger than 0.5 x 0.5 inches. Before you print, run the file through the Mailpiece Size Checker in the EDDM online tool.
How to Run a Direct Mail Campaign, Step by Step
Pick who gets it, design one piece around one offer, give people a trackable way to respond and test small before you mail big.
-
Set the goal and the audience
New customers within a mile (EDDM) or bringing back last year's customers (your list). One goal per campaign.
-
Build the list or pick the routes
For EDDM, choose routes by distance and household type. For a list, use customers who bought from you and remove anyone who asked to stop.
-
Choose the piece
A postcard for a simple offer, a letter for customers, a product catalog if you sell many items, or a brochure if you need to explain a service (how to make a brochure).
-
Write one offer with a deadline
"Free teeth whitening with your first cleaning, through November 30." No deadline, no urgency.
-
Add a response you can track
A QR code with UTM tags to its own page, a promo code and, if volume justifies it, a dedicated phone number.
-
Test a small batch
Mail 1,000 to two areas or with two offers, compare, and only then print 10,000.
-
Mail and log everything
Dates, routes, quantities and total cost. Without it, you cannot calculate anything later.
How to Track Direct Mail: Response Rate, QR Codes and Promo Codes
Count the responses that can only come from the mailer and divide the campaign cost by them: that is your cost per response.
- A direct mail QR code with UTM tags pointing to a page built only for the campaign. Build the link with our UTM builder and turn it into a QR code.
- A promo code printed on the piece ("NEIGHBOR10") and logged at checkout.
- A dedicated phone number or text line, if your volume justifies it.
- "How did you hear about us?" at checkout and on forms, with "mailer" as an option.
A worked example: you mail 5,000 postcards and pay $2,100 for printing and postage. You get 40 responses, a 0.8% response rate and $52.50 per response. If 25 of them buy and each customer brings $120 in margin, you make $3,000 on $2,100. If the margin is not there, change the route or the offer, not the quantity.
If you also hang posters around the neighborhood, use the same offer with a different code so you can tell them apart. Our guide to poster design covers that piece.
What is a good direct mail response rate?
The only good direct mail response rate is the one that makes your cost per response lower than what a customer is worth to you. Industry averages float around online, but they mix house lists, prospect lists and every kind of business, so they say little about your mailer. Your own tracked test is the number to trust.
Direct Mail Lists and Opt-Outs: DMAchoice and Your Own Suppression List
Mail people who know you or have a reason to hear from you, and keep a do-not-mail list that you actually use.
- Your own customers first: they respond best, and you already have a relationship with them.
- Rented lists: ask the broker where the data comes from and how recently it was updated against change-of-address records.
- Internal suppression list: when someone asks you to stop, remove them from every future mailing and share the file with your mail house.
- EDDM pieces go to every address on the route, so they do not use personal data, but the same honesty rules apply to what you print.
Do you have to honor DMAchoice?
Only if your company or your mailing vendor participates, because DMAchoice is a voluntary mail preference service run by the Association of National Advertisers. Consumers use it to opt out of prospect mail from participating companies. Even if you are not bound by it, scrubbing a rented list against it cuts waste and complaints.
Direct Mail Examples That Get Responses (and Mistakes)
Good direct mail examples share three traits: the right people or neighborhood, a specific offer with a deadline, and a response you can count.
- Dental office in Tampa, postcard to patients: "Marta, it's time for your checkup," with a code to book before month's end.
- Pizza place in Columbus, EDDM within half a mile: a fridge magnet with the menu, the order line and "NEIGHBOR10" for the first order.
- Yoga studio in Denver, letter to lapsed members: a signed note from the owner with a come-back offer for September and a QR code to book.
Act as a direct mail marketing expert. My business: [type] in [city and neighborhood]. I want [new customers or lapsed customers back]. Give me 3 direct mail campaign ideas. For each: the piece, the main headline in 10 words or fewer, an offer with a deadline, the promo code and how to measure cost per response.
Frequently asked questions about direct mail marketing
What are the disadvantages of direct mail advertising?
The main ones are cost per contact, lead time and waste. Printing and postage cost far more per person than an email, a campaign takes days or weeks from artwork to mailbox, and pieces sent to the wrong people go straight to the recycling bin. It is also harder to track than digital ads unless you build tracking in. You reduce all three with tight targeting, a small test before a big drop and a code or QR that only appears on the mailer.
How do you choose a direct mail company?
Decide first what you need: printing only, printing plus mailing, or a full service that also sources lists and tracks responses. Ask each company where its lists come from, how it cleans addresses against the USPS change-of-address data, whether it handles EDDM paperwork and what proof of mailing you get. Request a sample of a past mailer and a quote for the same quantity and size from two or three vendors. Avoid anyone who promises a response rate before seeing your offer.
How do you make direct mail advertising?
Start with one offer and one audience, then design the piece around it. Put a headline of a few words that names the benefit, a strong image, the offer with its deadline and one clear call to action, like a QR code, a phone number or a short web address. Keep the back simple: details, address and a code to track. Postcards work best for simple offers; letters work better when you need to explain more or speak to existing customers.
Does direct mail still work?
Yes, when it is targeted, local and tracked. A neighborhood restaurant, a dentist or a home services company can still get customers from a well-aimed postcard, and existing customers respond better than strangers. What no longer works is mailing thousands of generic flyers with no offer and no way to measure. Test a small batch with a unique code, calculate your cost per response and only scale the version that pays for itself.
Is direct mail marketing legal?
Yes. Sending advertising by mail is legal in the US, but the content must follow the same truth-in-advertising rules as any ad under the FTC Act: no deceptive claims, clear terms and real offers. Mail that looks like a government notice or a sweepstakes has extra rules under the Deceptive Mail Prevention and Enforcement Act. If you use personal data or regulated offers, like credit or health products, check the specific laws for your industry before you mail.
How much does a direct mail campaign cost?
It depends on four things: the format (postcard, letter or catalog), the quantity, postage and whether you need a mailing list. Design and printing come first, then postage, which falls per piece as volume rises, and list rental if you are not mailing your own customers or using EDDM. Ask for an all-in quote per piece and work backwards: divide it by your expected response rate to see what each response will cost you.
