# Direct Mail Campaign Ideas That Fill a Route Instead of a Mailbox

EDDM samples and campaign examples by business type, each with its size, offer, tracking code and drop date, plus the steps from carrier route to mailbox.

EDDM Retail carries up to 5,000 pieces per ZIP code per day with no mailing list and no permit, and you pay at the Post Office that serves the routes you picked.
To qualify as a flat the piece has to beat one of three thresholds: longer than 10.5 inches, taller than 6.125 inches, or thicker than 0.25 inches. Nothing may exceed 15 by 12 by 0.75 inches.
A 4 by 6 postcard is a letter to USPS and cannot go EDDM Retail. The smallest size most printers stock for it is 6.5 by 9.
You buy whole carrier routes, never households, so the aim is only as good as the route you chose.
Direct mail postcards at 4OVER4.COM start at $89.68, and letters, flyers and brochures at $238.73.
EDDM moves as Marketing Mail, which is not date guaranteed, so an offer that expires on a named Saturday is a campaign built to fail.
Every EDDM example and sample on this page follows one rule: a saturation offer rides on an EDDM flat of 6.5 by 9 inches or larger, such as a 6 x 11 postcard or an 8.5 x 11 flyer, and anything that needs a name on it rides on an addressed letter with a mailing list. Choose the campaign shape first and let it pick the piece. Every campaign below names the piece, a starting quantity and when to drop it, because those three decisions settle the result long before the artwork does.
An EDDM sample answers two questions a screen cannot: how the stock feels after a carrier has handled it, and how the offer reads face down in a stack of mail. Order the free samples first, which ship free, and compare the 14pt and 16pt cover stocks in gloss, matte and uncoated before you choose one for a route.
6 x 11 postcard. The direct mail postcard size in our configurator that qualifies as an EDDM flat, because it runs longer than 10.5 inches. Use it for one offer with a coupon strip along the bottom.
8.5 x 11 or 9 x 12 flyer. Direct mail flyers on 100# Gloss Cover or 100# Gloss Text qualify on both length and height, and carry a menu, a price list or a service checklist.
Folded brochure. An 11 x 17 sheet with a half fold or trifold becomes the fridge piece from campaign 4 below.
Quantities are a starting point for a first campaign, not a ceiling. A carrier route holds a few hundred to well over a thousand households, so three to five routes can run to several thousand pieces per drop, still under the EDDM Retail cap of 5,000 pieces per ZIP code per day. When one route answers, add the route next to it on the USPS map for the next drop rather than starting in a new ZIP code. You can order direct mail postcards in every EDDM size from the configurator.
An EDDM Retail campaign runs in five steps, and the post office counter only sees the last one. Plan them in this order and the drop date holds.
Choose carrier routes. Open the USPS online tool, search by ZIP code, and pick routes by household count, average age, average household size and average income.
Size the piece. The standard EDDM size is a flat: longer than 10.5 inches, taller than 6.125 inches or thicker than 0.25 inches. Most campaigns use 6.5 by 9 inches or larger; at 4OVER4.COM that means a 6 x 11 postcard or an 8.5 x 11 flyer.
Print. Direct mail postcards print on 14pt or 16pt cover with a 4 business day standard turnaround, and 4/1 ink puts black on the back, enough for the indicia and the address block.
Bundle. Stack the pieces in bundles of 50 to 100 with a facing slip on each bundle.
Fill the paperwork and drop it. Complete the postage statement at the counter of the Post Office that delivers your routes and pay there, up to 5,000 pieces per ZIP code per day.
The cheapest way to run one is EDDM Retail with the smallest piece that qualifies, a short list of routes, and all the drops printed in one run. Postage is the flat EDDM rate USPS publishes per piece, and print cost per piece falls with volume: in the default configuration, 500 postcards cost $89.68 and 5,000 cost $241.51, so printing three drops of 1,500 together costs less per piece than printing each one alone.
EDDM saves you the list and costs you the aim. You buy every door on a USPS carrier route, a few hundred to well over a thousand households at a time, at the flat saturation rate, and you never see a single name. For a pizzeria, a dentist or a roofer whose customer is anyone within four miles, that is the cheapest reach in print. For a firm that sells to thirty accounts across a metro area, it is a way to pay for nine hundred doors that will never call.
The second half of the trade is format. EDDM only carries flats, so the piece has to break one of three thresholds: longer than 10.5 inches, taller than 6.125 inches, or thicker than 0.25 inches, and nothing may exceed 15 by 12 by 0.75. The 4 by 6 postcard most people picture is a letter as far as USPS is concerned, and it cannot ride EDDM Retail at all. That single rule is why every EDDM size chart on earth starts at 6.5 by 9.
Our EDDM postcard sizes guide lists the qualifying dimensions in detail, and the direct mail printing and mailing services page covers what we handle once the artwork is approved. If you have never run a drop before, read how direct mail marketing works first, then come back to the campaign shapes below. For the whole handoff, see our mailing services that get your print into real mailboxes.
No permit, no list, no addresses. You choose routes in the USPS online tool by ZIP code, which shows the household count on each route along with average age, average household size and average income. You bundle the pieces in stacks of 50 to 100 with a facing slip on each stack, fill in the postage statement at the counter, and pay at the Post Office that delivers those routes. The cap is 5,000 pieces per ZIP code per day. Beyond that you need a permit and a bulk mail entry unit.
The address side is where jobs get rejected. Leave the upper right corner clear for the indicia, print the words EDDM Retail in that indicia block, and set the address area as the ECRWSS endorsement over a Local Postal Customer line. No name, no street. If the artwork fills that corner with a headline, the counter will send it back and the drop date moves.
Three situations flip the decision. Selling something with a long sales cycle and a high ticket, where you know the twenty companies worth winning. Mailing your own customers, where you already have the addresses and the history. Chasing new movers or a specific trade, where the value sits in the targeting and not the volume. In all three, an addressed direct mail letter at $238.73 beats a route buy, because the piece can say something only that reader would recognize.
The B2B version of this is worth its own read: eight B2B direct mail ideas covers what to put in an envelope when the recipient has a gatekeeper. The honest limit of EDDM is that it cannot do any of that. It is a volume instrument, and pretending otherwise is how people conclude that direct mail does not work.
Each of these names the piece, a starting quantity and when to drop it, because those three decisions decide the result long before the design does. They are ordered from the simplest to run to the ones that need a list and a bit of patience.
The pieces come from four products: direct mail postcards at $89.68, direct mail flyers and direct mail brochures at $238.73, and letters at the same price when the campaign needs an envelope.
1. Saturate the routes around a new door. Pick the three to five carrier routes nearest the location, print a 6.5 by 9 postcard with the address, a map and one opening offer, and drop it ten days before you open. Then drop the same routes again the week after opening. The second drop is the one that works, and it is the one most people skip because the first felt expensive.
2. Ring a competitor instead of yourself. Choose the routes that surround their location rather than yours, and lead with the one thing you do that they do not: later hours, free parking, a same day slot. This is the campaign where a weak offer shows up immediately, because the reader already has a supplier and is being asked to change.
3. Beat the season by a month. Gutter cleaning mailed in the first week of heavy rain competes with panic. Mailed four weeks earlier, on an 8.5 by 11 flyer with a checklist the reader can tick, it competes with nothing. Same logic for tax prep, heating service, pool opening, back to school. The mailbox is emptier before the rush and so is the calendar.
4. Print something that earns fridge space. A menu, a price list, a maintenance schedule, an emergency number. A folded direct mail brochure gets kept where a discount postcard gets binned, which changes the arithmetic completely: one piece that survives six weeks on a fridge door is worth several that got a glance. Aim for a Thursday in home window if the offer runs over a weekend.
Five worked examples, written as illustrations of the four campaigns above rather than as real results. Each lists the size, the headline offer, the call to action and the tracking code. The postcards print on 14pt cover and the flyers on 100# Gloss Cover.
Restaurant menu card. An 8.5 x 11 flyer with the full takeout menu on the back. Headline: Free delivery on your first order this month. Call to action: order by phone or online. Tracking code: MENU1 at checkout. This is campaign 4, the fridge piece.
HVAC tune up offer. A 6 x 11 postcard mailed four weeks before the first cold snap. Headline: Furnace tune up, book before the rush. Call to action: call to book a slot. Tracking code: a phone extension used only on this card. This is campaign 3.
Realtor just sold card. A 6 x 11 postcard with a photo of the house and the price band. Headline: Just sold on your street. Call to action: ask for a free home value estimate. Tracking code: a URL ending in the route number. This is campaign 1, pointed at the routes around one sale.
Dental new patient offer. A 6 x 11 postcard to the three or four routes inside a short drive. Headline: New patient exam and cleaning offer. Call to action: book online. Tracking code: NEWSMILE when booking. This is campaign 1 again, with a travel radius instead of an opening date.
Gym opening. A 9 x 12 flyer with the class schedule. Headline: Opening month, first week free. Call to action: visit the front desk with the flyer. Tracking code: the flyer itself, collected at the desk. This is campaign 2 if a rival gym sits two routes away.
5. Sell an event with a window, not a date. An open house, a sale weekend, a demo day. Marketing Mail is not date guaranteed, so print a range such as valid through the end of the month rather than a single Saturday. A piece that lands two days after the event is money set on fire, and it happens to somebody every season.
6. Run the same route three times. Take a quarter of the routes you could afford to hit once, and hit them three times about three weeks apart with the same look and a different offer. Recognition is the whole point. A household that has seen your colors twice reads the third piece instead of sorting it, and a single drop across four times the area never gets that far.
7. Split two routes and count the calls. Same postcard, same drop day, two response codes: a distinct phone extension, a URL with a suffix, or a coupon code per route. Pick routes with similar household counts so the comparison means something. This is the cheapest market research a local business can buy, and it settles arguments about the offer that would otherwise run for years.
8. Write to the accounts that actually matter. Twenty to two hundred names from your own records, in an envelope, First Class, arriving Tuesday to Thursday. Reference something specific about the recipient in the first line, because that is the only thing that separates a letter from a mailer. Send it, then call the following week. The letter is not the campaign, the letter is the reason the call gets taken.
The most common mistake in a first campaign is spreading a fixed budget as thin as it will go. Twenty routes once looks impressive on a map and reads as a stranger in the mailbox. Five routes four times looks modest and reads as a business that is clearly around. If the budget only stretches one way, cut the area and keep the frequency.
Route selection deserves ten minutes rather than ten seconds. The USPS tool shows the household count, the average income, the average age and the average household size for every route, which is enough to drop a route that skews far from your customer before you have paid for it. A route full of student rentals is a poor buy for a landscaper and a fine one for a pizzeria.
Then work the calendar backwards. Print turnaround, transit to you, your bundling time, the counter visit, and the days USPS takes to work Marketing Mail through the plant and onto the route. None of that is date guaranteed, so leave slack at both ends and never build the offer around one named day. The winning direct mail campaign guide walks the full sequence, and how to create a successful direct mail campaign covers the planning side in more depth.
A campaign you cannot measure is a campaign you will argue about. Give every drop its own trackable handle: a phone extension, a landing URL, a coupon code, or simply a line that tells the reader to mention the card. Then write the number down on the day it arrives, not at the end of the quarter from memory.
Response arrives in a long tail. A saturation drop produces a cluster in the first ten days and a slow trickle for a month or more, and pieces that got kept, the menus and the price lists, produce calls months later with no obvious trigger. Judge a route on a six week window, not a weekend. There are worked examples in brilliant examples of direct mail marketing.
Postage and print are separate budgets and people forget the first one. The print side is straightforward: direct mail postcards start at $89.68 and flyers at $238.73, with the unit cost falling as the run grows, which is one more argument for hitting fewer routes more often. The postage side is the flat EDDM rate published by USPS per piece, multiplied by every door on every route you chose, and it is usually the larger of the two lines. Before you split the budget, read direct mail postcards vs flyers vs letters, and which one actually gets read.
Choose the stock with the drop in mind. A postcard needs enough rigidity to survive being bundled, carried in a satchel and pushed through a slot, so 14pt or 16pt is the sensible floor. Gloss photographs well and shows fingerprints. Uncoated takes a pen, which matters if you want a handwritten line or a name filled in. Matte sits between the two and reads calmly in a hand.
Direct mail postcards come in nine sizes from 4 x 6 to 6 x 11 inches, on 14pt or 16pt gloss, matte or High Gloss UV cover or 14pt uncoated cover, printed 4/0, 4/1 or 4/4, with a 4 business day standard turnaround. In the default configuration, 500 cost $89.68, about 18 cents a piece, and 5,000 cost $241.51, under 5 cents a piece. That matters more on a mailer than on most jobs, because a route buy commits you to a fixed number of doors and the only way to bring the unit cost down is to print the drops together. The numbers below come from the live configurator.
Real configurator numbers, where a larger run drops the cost of every piece in it.
A mailer is handled more than almost anything else you print. It is bundled, carried in a satchel, pushed through a slot, dropped on a hall floor and picked up with the rest of the post. Thin stock arrives with soft corners and reads as junk before anyone has looked at the offer, so 14pt is the floor and 16pt is the safer choice on anything at 9 by 12 or larger.
Qualifying sizes on heavy stock, priced from $89.68.
Finish changes both look and behavior. Gloss lifts photography and color and shows fingerprints, which is fine on a piece meant to be read once. Matte reads calmly in the hand and photographs poorly, which suits a service offer with little imagery. Uncoated takes pen ink, so choose it when a name, a date or a handwritten line is part of the plan. For anything that needs to survive weeks on a fridge, a folded direct mail brochure on heavier stock outlasts a single card.
The right campaign depends far more on your travel radius and your ticket size than on your industry, but these are the patterns that repeat.
Restaurants and takeaways. A menu that stays on a fridge beats four discount cards that do not. Print a folded brochure, mail a small route set often, and let recognition do the work.
Home services. Season ahead reminders on flyers, sent to the routes you already service. Your van has been on those streets, so the name is half familiar before the piece lands.
Dental and medical practices. Saturate the three or four routes inside a realistic travel radius. Nobody drives across a city for a check up, so a wide drop mostly buys waste.
Retail and new openings. Two drops on the closest routes, one before opening and one the week after. The second is the one that produces the visits.
Professional services and B2B. Skip EDDM. Twenty to two hundred addressed letters, First Class, followed by a call the next week, will outperform any route buy in this category.
Two more reads worth the time before you commit a budget: postcard marketing that converts for the offer and layout side, and where direct mail is heading next for how it now sits alongside digital rather than against it. If your calendar is built around holidays, Labor Day marketing and direct mail ideas is a worked example of timing a seasonal drop.
Fewer routes, more drops, and a piece that legally qualifies
Start with three to five carrier routes closest to your door and mail them two or three times instead of blanketing twenty routes once. Print at 6.5 by 9 inches or larger so the piece qualifies as a flat, keep the upper right of the address side clear for the indicia, add 0.125 inch bleed, and give every drop its own phone extension or coupon code so you can count what came back.
Route or list, decide first. EDDM buys reach without aim. A mailing list buys aim without reach. Everything else about the campaign follows from that one choice.
The piece has to qualify. Longer than 10.5 inches, taller than 6.125 inches, or thicker than 0.25 inches. A 4 by 6 postcard does not, at any price.
Frequency beats area. Five routes four times outperforms twenty routes once on the same budget, because the third piece is the one that gets read.
Never build an offer around a named day. Marketing Mail is not date guaranteed. Print a window and give yourself a week of slack at both ends.
Make every drop countable with its own code, extension or URL, and judge it over six weeks rather than a weekend.
4OVER4.COM prints the whole set, from direct mail postcards at $89.68 to brochures and letters at $238.73.
Design decisions that hold up in a mailbox
One offer, not four. A postcard with four offers gets read as a list of prices. One offer with a deadline gets read as a decision. Save the second offer for the second drop.
Keep the indicia corner empty. Upper right of the address side belongs to USPS. Design around it from the first layout instead of moving a headline the day before the drop.
Make the deadline a range. Marketing Mail delivery is not guaranteed to the day, so print a window such as through the end of the month. A named Saturday will burn you eventually.
Put the phone number twice. Once large near the offer and once small near the address block. People fold, cut and pin these pieces, and the number needs to survive it.
Print one and post it to yourself. Handle the real piece before you commit thousands. Stock weight, color under household light and how it reads face down in a stack all show up only on the finished card.
A mailed postcard costs $0.18 at 500 and an addressed letter $0.48, which is the whole trade-off.
Pick the size that qualifies, print it on stock that survives the bundle, and 4OVER4.COM turns it around fast enough to hit your in home week.
No. EDDM carries flats, and a piece only counts as a flat if it is longer than 10.5 inches, taller than 6.125 inches, or thicker than 0.25 inches. A 4 by 6 card fails all three, so USPS treats it as a letter and it has to be addressed and stamped like any other letter mail. The smallest size that qualifies in practice is 6.5 by 9, which is why that size dominates EDDM campaigns. If you already have 4 by 6 artwork, the fastest fix is to rebuild it at 6.5 by 9 rather than argue at the counter.
Do I need a mailing permit to run an EDDM campaign?
Not for EDDM Retail, which is the version most small businesses use. You select routes in the USPS online tool, bundle the pieces in stacks of 50 to 100 with facing slips, complete the postage statement at the counter and pay there, with a cap of 5,000 pieces per ZIP code per day. Above that cap, or if you want to drop at a bulk mail entry unit rather than the local Post Office, you need a permit. For a first campaign covering a handful of routes, the Retail path is almost always the right one.
How many carrier routes should a first campaign cover?
Fewer than you want to, mailed more times than feels necessary. Three to five routes closest to your door, hit two or three times, will teach you more and produce more calls than a single drop across twenty routes for the same money. Frequency is what turns an unfamiliar name into a familiar one, and the third piece is usually the one that gets read rather than sorted. Once a route has proven it responds, expand outward from it rather than starting again somewhere new.
How long after I drop the mail does it land?
USPS handles EDDM as Marketing Mail, which is not date guaranteed and moves more slowly than First Class. Plan on several days between the counter and the route, and build the calendar backwards from the week you want it in home rather than the day. That means printing early, allowing transit time to you, and leaving slack before the offer window opens. The practical rule is simple: never print a deadline that depends on delivery landing on one specific day.
How do I tell whether the campaign actually worked?
Give each drop its own trackable handle before it prints. A dedicated phone extension, a URL with a route suffix, a coupon code, or a line asking the caller to mention the card. Write down responses on the day they arrive rather than reconstructing the quarter later. Then judge the result over about six weeks, because saturation mail produces a cluster in the first ten days and a long trickle afterwards, and pieces people keep, such as menus and price lists, generate calls months later with no obvious trigger.
