5 Quick Steps to Send Direct Mail Postcards

Set a goal and offer, design for a three-second glance, build a clean list, address and sort to postal spec, then pick a postage rate.
To send direct mail postcards, work through five steps: set one clear goal and offer, design the card around a single call to action, build and clean your mailing list, address and presort the cards to postal specification, then choose a postage rate and drop the batch. The fastest version is to hand the printing, addressing, sorting, and postage to one print-and-mail service so the campaign leaves your hands as a single order.
Print and mail service
We print, address, and mail your postcards as one order
If all you want is cards in mailboxes, start here. 4OVER4.COM prints your direct mail postcards, standardizes and barcodes every address, presorts the run to postal specification, applies postage, and releases the trays into the mailstream for you. You upload the artwork and supply or build the list. There is no second vendor, no hand-addressing, no tray in the trunk of your car, and no Post Office line. The smallest practical drop is a single carrier route through EDDM, which saturates that route by route number and needs no mailing list at all. The same direct mail service mails flyers and other formats when a postcard is not the right one.
Quick start
Send direct mail postcards, the short version
If you mail the cards yourself, size and postage class move the cost most. The size table further down shows which card earns which rate and which one opens EDDM.
Why direct mail postcards still land when email gets skipped
Direct mail postcards get read because there is nothing to open. A postcard does not compete with an overflowing inbox or a folder full of promotions. It arrives in the hand, face up, with the message already showing. Nothing to open, nothing to unsubscribe from, no spam filter to clear. If you want the numbers behind that, the direct mail response rate benchmarks are a useful reality check before you set your own targets.
The catch is that "just print some postcards and mail them" hides five real decisions, and skipping any one of them quietly wastes the whole budget. Learning how to send direct mail postcards properly means treating it as a short pipeline: goal, design, list, addressing, postage. Get those five right and the campaign more or less runs itself.
This guide walks each step in order. For inspiration on what a strong card looks like, browse real work in the postcards printing lineup and a few brilliant examples of direct mail marketing.
Step 1: Set the goal and the offer
Before a single pixel is placed, answer one question: what should the person do after they read the card? A campaign that tries to do everything ends up asking for nothing. Pick a single action and build the whole drop around it.
- The one action. Call, book, visit the shop, redeem a code, or scan to a page. Choose one.
- The offer. Give a reason to act now. A dated discount, a free consult, a bundle, or a limited window all beat a vague "learn more."
- The audience. Name who you are mailing to in plain words, because that decides the list in Step 3.
- Budget and drop date. Work backward from when you want responses to arrive, and leave room for print and mail time.
- How you will measure it. A unique promo code, a QR code, a dedicated phone number, or a campaign landing page so every response is traceable to this card.
Tracking is the easiest part to skip, and it is the part that tells you whether to mail again. If you are weighing postcards against other channels first, the postcard marketing ROI benchmarks give you a grounded starting point for what a realistic return looks like.
Step 2: Design your postcards for a three-second read
Your card gets judged fast, usually somewhere between the mailbox and the recycling bin. Design for that moment. The front carries the hook, the back carries the detail, and a quiet zone stays reserved for the address and postage.
Front: one headline that names the benefit, one strong image, and the offer. Keep the logo modest and the call to action unmissable. Back: supporting details, fine print, contact options, a QR code, and a clean address block on the right side.
- Pick a mailing size. Standard runs are 4x6, 5x7, 6x9, and 6x11 inches. The size affects both the look and the postage tier, so lock it before you lay anything out.
- Mind bleed and safe zones. Extend background color past the trim, and keep text and logos inside the safe margin so nothing is cut.
- Leave the address panel clear. The mail service and the Post Office need clean space for the address, barcode, and indicia.
You do not need design software to do this well. Start from a layout in the online designer, grab a proven starting point from the free design templates, or follow the full walk-through on how to make postcards. Going big for impact? Oversized postcards give the headline more room, and the EDDM size and drop-off guide covers the dimensions that qualify for saturation mailing.
Step 3: Prepare a clean, targeted mailing list
A brilliant card mailed to the wrong people still fails. You have three ways to build the audience you named in Step 1.
- Your house list. Past and current customers already know you. Export names and addresses from your point-of-sale, CRM, or booking system.
- A rented, targeted list. Buy or rent a list filtered by geography, income, age, homeownership, or business type to reach new prospects who look like your best customers.
- EDDM by route. Every Door Direct Mail skips the list entirely and blankets every address on the carrier routes you choose, which is ideal for a local shop that wants a whole neighborhood.
Whichever route you pick, clean the file before it prints. Remove duplicates, delete incomplete records, standardize every address to the postal format, and update movers so cards do not bounce. A tidy list earns better postage rates and wastes fewer cards. If saturation is your plan, read how to size and submit an EDDM mailing first, then let the direct mail services team handle the list processing and drop for you.
Step 4: Address and sort your postcards
This is the unglamorous step that quietly decides whether your cards arrive. Addressing is not just typing names. It is formatting the mailpiece so the Post Office can read, route, and deliver it at the lowest rate.
- Format every address to spec. Recipient line, delivery line, then city, state, and ZIP+4, all standardized. Clean data here is what earns presort discounts.
- Add a real return address. It handles undeliverable pieces and signals a legitimate sender.
- Reserve the postage and indicia area. The top-right corner stays clear for a stamp, meter, or printed indicia.
- Presort and barcode the batch. Grouping mail by ZIP and applying an Intelligent Mail barcode moves it faster and cheaper than loose, unsorted cards.
If any of that reads like a lot, it is, which is why a print-and-mail service is worth handing it to. Want to understand the layout yourself first? Our full breakdown of how to address a postcard correctly for mailing shows exactly where each element goes.
Step 5: Choose a postage rate and drop the mail
Postage is where speed, reach, and cost trade off. There is no single best rate, only the right one for this campaign. Three options cover almost every postcard drop.
- First-Class Mail. Fastest delivery and it forwards or returns undeliverable pieces. Best when timing matters, the audience is smaller, or address accuracy is uncertain.
- USPS Marketing Mail. Lower per-piece cost in exchange for slower, non-guaranteed delivery and a minimum volume. Best for large, non-urgent drops where budget rules.
- Every Door Direct Mail. A flat per-piece retail rate with no mailing list required, aimed at saturating chosen carrier routes. Best for local saturation on a fixed footprint.
Presorting and barcoding earn discounts on the first two options, which is why prepared mail beats stamped-by-hand mail on cost. Once the class is chosen and postage is applied, the batch goes into the mailstream and your five steps are done. Weighing this against email? The direct mail versus email comparison is worth a look before you commit the budget.
Direct mail postcard sizes and postage costs
Size decides postage more than anything else you choose. USPS prices a mailpiece by what it measures, not by what you call it, so a card that grows past the postcard dimensions is billed as a letter even though it still looks and feels like a postcard. Pick the size with the rate already in mind and the budget stops springing surprises on you.
| Card size | Mails at | EDDM eligible | Choose it when |
|---|---|---|---|
| 4 x 6 in | First-Class postcard rate, the cheapest per-piece band there is | No, too small for EDDM | Reminders, dated offers, appointment cards, tight budgets, big lists |
| 5 x 7 in | First-Class letter rate, or Marketing Mail once the volume is there | No, too small for EDDM | You need more room for the offer and still want First-Class speed |
| 6 x 9 in | First-Class letter rate, or Marketing Mail at volume | No, it sits just under the flat minimum | Menus, coupon cards, service reminders that must arrive fast |
| 6.25 x 9 in | EDDM retail flat rate, or Marketing Mail flat | Yes, the smallest size that qualifies | Neighborhood saturation with no mailing list to buy or clean |
| 8.5 x 11 in | EDDM retail flat rate, or Marketing Mail flat | Yes | Multi-offer sheets, grand openings, real estate and auto mailers |
Two postal rules explain that whole table. A card only earns the First-Class postcard price while it stays inside the postcard dimensions, which top out at 6 inches long by 4.25 inches high; one eighth of an inch over and it is a letter. EDDM works from the opposite end: the piece has to be bigger than letter size, more than 6.125 inches high or more than 11.5 inches long, which is why 6.25 x 9 rides an EDDM drop and 6 x 9 does not. The trap is a 6 x 11 card, which looks plenty big for EDDM and misses on both measurements.
Thickness matters too. A mailable card has to be at least 0.007 inch thick, so 14pt and 16pt card stock both clear the bar comfortably while text-weight paper gets rejected as a flimsy. That is one reason we print direct mail postcards on card stock rather than sheet paper: the run has to survive the sorting equipment before anyone reads it. Compare finishes and sizes across the postcards printing lineup. Direct Mail Postcards come in nine sizes up to 6 x 11, so a saturation drop at 6.25 x 9 or larger runs through the EDDM service.
Let 4OVER4 print, address, and mail it for you
Everything above collapses into a single order when a print-and-mail service runs it. Instead of printing at one place, buying a list at another, hand-addressing cards, and standing in line at the Post Office, you upload the design, hand over or build the list, and approve the drop. You pick one of nine sizes from 4 x 6 to 6 x 11 inches, a 14pt or 16pt gloss, matte or UV coated stock or 14pt uncoated, and a run from 500 cards, and production takes 4 business days before the mail date.
4OVER4.COM prints your Direct Mail Postcards on the stock and size you choose, addresses and presorts every piece, applies postage, and releases the batch into the mailstream. Because the run is presorted and barcoded, it qualifies for the lower postage tiers that hand-stamped mail never reaches. The same service covers mailing flyers and the wider direct mail services lineup when a postcard is not the right format.
That leaves you with the two things that actually move results: a sharp offer and a clean list. The logistics stop being your problem.
What it costs, and the mistakes that waste a drop
Two numbers make up the total: printing and postage. Printing scales with size, paper stock, coating, and quantity, and the per-card price falls steeply as the run grows, so a larger drop is almost always cheaper per piece. Postage scales with the class you pick and how well the mail is prepared, which is why the presorting in Step 4 pays for itself. The live specs and price table further down this page show current per-unit pricing on Direct Mail Postcards.
Avoid the mistakes that quietly sink otherwise good campaigns:
- No offer or a weak one. "We exist" is not a reason to respond. Give a dated, specific reason to act.
- A cluttered front. Two headlines and three calls to action equal zero. One of each wins.
- A dirty list. Duplicates, typos, and movers burn postage on cards nobody reads.
- The wrong postage. Paying First-Class for a non-urgent 5,000-piece drop, or losing days waiting on Marketing Mail for a time-sensitive sale.
- No tracking. Without a code, QR, or landing page you cannot tell a winner from a loser, so you cannot repeat what worked.

Common Questions
Common questions about sending direct mail postcards
How do I send direct mail postcards, step by step?
Follow the five step sections above in order. If you mail the cards yourself, the last step is taking the sorted trays to the Post Office; with a print-and-mail order, the printer applies the postage and releases the trays into the mailstream for you.
What is step 1, setting goals for a postcard campaign?
Step 1 is deciding what success looks like before anything else. Pick the single action you want, such as a call, a store visit, or an online order, write the offer that makes that action worth it, name the audience you are mailing to, set a budget and drop date, and choose how you will track results with a promo code, QR code, or dedicated landing page. Every later choice becomes easier once the goal is fixed.
What is step 2, designing your postcards?
Design the front to be understood in about three seconds: one headline, one image, and one offer, with your logo small. Put the details, fine print, and address panel on the back, and keep a clear zone for the mailing address and postage. Stay inside the safe area, extend color to full bleed, and pick a standard size such as 4x6, 5x7, 6x9, or 6x11 so it qualifies for the postage rate you want.
Do I buy a list or blanket the carrier routes?
You have three routes. Mail your own house list of past and current customers, rent a targeted list filtered by geography, demographics, or business type to reach new prospects, or use EDDM to blanket every address on a carrier route without a list at all. Whichever you choose, clean the file first by removing duplicates and running it against USPS address standardization so cards actually get delivered.
What does it cost to send direct mail postcards and how is the price set?
Two numbers drive the total: printing and postage. Printing depends on size, paper stock, coating, and quantity, and the per-card price drops sharply as the run gets larger. Postage depends on the class and how well the mail is prepared, so a presorted, barcoded First-Class or Marketing Mail postcard costs less to send than an unsorted one, and EDDM carries its own flat per-piece rate. Use the live specs and price table on this page to see current per-unit pricing on Direct Mail Postcards.
Is it cheaper to print and mail postcards myself or use a mailing service?
For a handful of cards, printing at home and buying stamps is fine. Once you are sending hundreds or thousands, a print-and-mail service almost always wins because it earns presort postage discounts, standardizes every address, and skips the trip to the Post Office. 4OVER4.COM prints your Direct Mail Postcards, addresses and sorts them, applies postage, and drops them into the mailstream so the campaign leaves your hands as one order.
What postcard sizes qualify for direct mail and EDDM?
Common direct mail sizes are 4x6, 5x7, 6x9, and 6x11 inches. For Every Door Direct Mail the piece has to be larger than letter size, so it must be more than 6.125 inches high or more than 11.5 inches long: 6.25 x 9 and 8.5 x 11 qualify, while 6 x 11 misses on both counts. Sizes affect both eligibility and postage, so confirm the size before you design. Our EDDM size guide walks through the exact dimensions that keep you in the flat, per-piece EDDM rate.
