On paper, direct mail in Littleton, MA and a drop in Groton are the same buy. The two towns sit next to each other northwest of Westford, they hold nearly the same number of households, and a printer will quote you the same price per card for both. Then you pull the carrier routes and the resemblance falls apart. Littleton packs its homes into about 17 square miles. Groton spreads a similar count across roughly 33. That single difference decides which routes are worth buying, how many calls a crew can run in a day, and which of the two towns you should add first.
The short version: Littleton and Groton have almost identical household counts, so the postage is almost identical. The driving is not. Littleton is compact and clustered, which makes it the cheaper second town for most Westford-based crews. Groton is twice the land area, so buy its dense pockets first rather than the whole town. Track the two separately or you will never know which one paid.
Why direct mail in Littleton, MA and Groton are not the same buy
Postage does not care about geography. Every Door Direct Mail charges per piece, so 3,700 homes in a tight subdivision cost the same to reach as 3,700 homes on two-acre lots. That is what makes mail feel like a flat purchase.
Your truck is where the geography shows up. The unit that matters is the USPS carrier route, one carrier's daily path, usually 400 to 800 addresses. In a dense town a route might be a handful of connected streets. In a rural town the same address count can stretch across several miles of road. Same postage, very different day for whoever has to drive it.
So the question is not "which town has more homes." It is "how many homes can I actually serve per hour of windshield time." We walked through reading the underlying data in the guide to every door direct mail routes, and the postage and printing side in what EDDM costs.
What Littleton looks like on the map
Littleton holds roughly 10,000 people in something like 3,700 households, all inside the 01460 ZIP and about 17 square miles. Divide by typical route size and you land near 6 to 10 residential routes. Confirm the real count on the free USPS tool at eddm.usps.com before you budget anything.
The useful thing about Littleton is how clustered it is. Most of the housing sits in identifiable pockets: the neighborhoods around Littleton Common, the streets off King Street and Great Road, and the newer building near the Route 2 and I-495 interchange. The commuter rail stop pulls in households that work toward Boston, which in practice means more two-income owners who hire the work out instead of doing it on a Saturday.
For a crew based in Westford, Littleton is a 10 to 15 minute drive, the same tier as Chelmsford and Acton. A tech can finish a call and be at the next one in a few minutes without leaving the route you mailed.
What Groton looks like on the map
Groton holds roughly 11,000 people in about 4,000 households, so it is slightly larger than Littleton by count. It covers close to 33 square miles and splits across two ZIPs, 01450 for most of the town and 01472 for West Groton. Older housing stock, bigger lots, and a lot of conservation land in between.
That spread is the whole story. The same 4,000 households produce routes that wander, and a service call on one side of town can be 15 minutes from a call on the other side, before you have driven anywhere near Westford. Groton also sits in the 20 to 30 minute tier from a Westford base, so you are paying the commute twice.
Groton does have dense pockets worth knowing. The village center, West Groton, and the smaller lots around Lost Lake are tighter than the rest of the town. If you mail Groton at all, start there. Buying two or three of the dense routes tells you whether the town responds without committing to the 30 square miles of road behind it.
What each drop actually costs
The three lines are the same ones we use for any local drop: postage at about 20 to 24 cents per piece, printing at roughly 5 to 12 cents once you are running a few thousand, and design as a one-time cost you spread across the season. All in, budget 30 to 50 cents per delivered home.
- All of Littleton, about 3,700 homes. Roughly $1,100 to $1,850 a drop on your own.
- All of Groton, about 4,000 homes. Roughly $1,200 to $2,000 a drop on your own.
- Three dense Groton routes, about 1,800 homes. Roughly $550 to $900, which is a far easier first test.
Those are the mail costs, not the total cost of serving the town. Add the drive time and Groton is the more expensive town to work even though the postage is nearly identical. That is the number most owners leave out. A shared mailer slot changes the math again, since the card cost is split across the businesses on it.
Sequence them instead of choosing
You do not have to pick one forever. You do have to pick an order.
- Mail Littleton first, two drops, four to six weeks apart. Closer, denser, and cheaper to serve.
- If Littleton produces, test Groton with the dense routes only. Do not blanket it on the first try.
- Expand into the wider Groton routes only once you have enough volume there to run two or three calls in one trip.
The rule from the Middlesex County guide still holds: do not mail a town you cannot serve the same week. In Groton that rule bites harder, because a Thursday call on the far side of town is easy to push to next Tuesday, and that is how a good drop turns into a bad review.
Track the two towns separately
Run a different code on each town's card. A distinct QR destination, a distinct promo code, or a separate tracking number per town, whatever you will actually keep up with. Then after two drops you can compare calls per thousand homes in Littleton against Groton and stop guessing which one is carrying the budget.
One warning worth repeating: the drop only works if someone answers. A homeowner in West Groton who gets voicemail calls the next card on the counter. If your phone goes unanswered during job hours, fix that before you spend on a second town. The AI Blueprint covers whether an after-hours answer is worth it for your setup.
Two neighboring towns, nearly the same household count, and two very different jobs. Pull both route maps side by side on the USPS tool before you buy, and the order to run them becomes obvious.
