Every door direct mail is the simplest way to put a postcard in every mailbox on a street without buying a list. The part most owners get wrong is the routes. EDDM does not mail a whole town in one click. It mails USPS carrier routes, one at a time, and the routes you choose decide who sees your card and what the drop costs. Pick the wrong routes and you pay to reach renters and empty offices. Pick the right ones and every card lands on a home that could actually hire you. This guide shows how to read the route data and build a plan that fits your service area.
The short version: A route is one mail carrier's daily path, usually 400 to 800 addresses. Use the free USPS tool to see each route's home count, age, and income, rank routes by value, cluster the good ones near your base, and check the budget before you commit. Then time the drop to the season and track which routes respond.
How every door direct mail routes actually work
A carrier route is the daily walking or driving path one mail carrier covers. USPS splits every ZIP code into these routes, and most of them hold somewhere between 400 and 800 addresses. When you run an EDDM campaign, you are not buying a ZIP code. You are buying a list of specific routes, and your card goes to every active address on each one. There is no skipping houses and no list to rent. That is the trade: full coverage of a route, with the route as your smallest unit of control.
Two route types matter. Residential routes are mostly homes, which is what a home-service business wants. Business routes are storefronts and offices. The USPS tool labels both, and you can choose residential only so you stop paying to mail a strip mall.
Find your routes with the USPS tool
USPS runs a free route-selection tool at eddm.usps.com. Type in your business address or a ZIP code and a map loads with every carrier route drawn as a shaded area. Click a route and a panel shows the numbers that matter: how many residential addresses it holds, how many businesses, and a rough read on the age, income, and household size of the people living there.
You do not need a permit or a mailing list to use EDDM Retail. You build the route list in the tool, pay at the Post Office, and drop the bundles. The one limit to watch is volume: EDDM Retail caps you at 5,000 pieces per ZIP code per day, with a minimum of 200 pieces per route. For a local home-service business mailing a few hundred to a few thousand homes, those limits are rarely a problem.
Read the route data before you pick
The map makes it tempting to grab every route near you. Slow down and read three columns first.
- Residential count. This is your real reach. A route with 700 homes is worth more than one with 700 addresses where half are businesses.
- Median age and income. The tool shows census-based estimates. A roofer or HVAC company usually wants owner-occupied homes, which skew older and higher-income than apartment-heavy routes. A route full of rentals is a weak fit for a $12,000 job.
- Cost per route. Multiply the residential count by the per-piece postage to see what each route costs before you commit. Routes are not all the same size, so the cost swings.
Put those numbers in a simple list and you can rank routes by value instead of by what happens to look close on the map.
Build a route plan around your base
The best route plans are tight and connected. Start at your shop or your busiest neighborhood and add routes outward until you hit your budget or your drive-time limit. Three rules keep the plan honest:
- Cap the drive. If you would not send a truck there for a service call, do not mail it. A lead 45 minutes away costs more to serve than it is worth.
- Cluster the routes. Adjacent routes let you reuse the same offer and the same follow-up. Routes scattered across three towns are harder to track and harder to serve.
- Match the home to the job. Selling furnace replacements? Weight toward routes with older homes and older owners. Selling recurring cleaning? Higher-density routes with younger working households can fit better.
For a Westford-based company, that often means a handful of routes in Westford, then the nearest routes in Chelmsford, Acton, or Littleton, rather than a thin spray across all of Middlesex County.
Do the budget math
EDDM postage runs roughly 20 to 25 cents per piece for EDDM Retail, and rates change, so confirm the current number in the USPS tool. Printing a quality postcard adds somewhere around 5 to 15 cents per piece depending on size and quantity. Call it 30 to 40 cents all in.
Run a real example. Say you pick six residential routes that total 3,600 homes. At 35 cents per piece, that is about $1,260 for one drop. Mail that same plan four times across a season and you are near $5,000. Now you can decide whether the routes are worth it before you spend, instead of guessing after. For a full breakdown including design and printing, see our guide on what every door direct mail costs.
Time the drop and track it
Routes decide who sees the card. Timing decides whether they act. Mail before demand peaks, not during it. A landscaper mails in late winter, before the spring rush. An HVAC company mails before the first heat wave and again before the first cold snap. Put a dated offer and a tracking number or QR code on the card so you can tell which routes responded. After one or two drops you will see which routes pull and which ones do not, and you can cut the dead ones from the next plan.
Where a shared card changes the route math
Mailing your own EDDM card means you carry the full postage and printing on every route. A shared neighborhood mailer splits that cost across several businesses on one card, with one business per category, so you reach the same routes for a fraction of the per-home cost and no competing plumber or roofer sits next to you. If you would rather hand off the route planning entirely, that is most of what we do. You can also see where automation like an after-hours AI answering setup fits once the calls start coming in, or look at how the shared mailer works on the home page.
Routes are the lever almost nobody pulls on EDDM. Most owners pick a ZIP, mail everyone, and hope. Spend an hour in the USPS tool reading home counts, age, and income, build a tight plan around your base, and you are mailing the homes that can actually hire you instead of paying to reach the rest.
