How to launch a store opening with measurable door-to-door distribution

A store opening is the one moment when almost every retail chain still buys door-to-door distribution. It makes sense. There is a new address, a clear radius around it and a few weeks in which the neighbourhood decides whether that shop becomes part of its routine. Paper can reach every home inside the radius, including the ones that will never see an ad on their phone.

What makes less sense is how it gets bought. Most retailers still buy flyer distribution blind: two photos and an invoice. The opening team does not know which buildings were covered, which streets responded or whether the leaflet is still bringing people in during week three. Door-to-door has ended up as the only channel in the opening plan that hands back no data.

It does not have to work that way. These are the four plays we use at CARTO so that an opening with door-to-door distribution is measured like any other channel. The minimum for a door drop is 25,000 units.

1. A QR on the front page that links to the app or to a coupon redeemable only at that store

The opening leaflet usually carries the logo, the address and a date. That is fine, but nobody can measure a date. What can be measured is an action. Put a QR code on the front page, not tucked away on the back, and point it at a destination that only makes sense for that store. Two options work. The first is the client's app, with a link that records that the download or the sign-up came from the leaflet for that opening. The second is a coupon that can only be redeemed at that store, with a code that belongs to the campaign.

Both turn the leaflet into something that leaves a trail. Every person who responds passes through a link that CARTO records, and that response is matched against the data the client already holds: the app, the coupons, the codes and the CRM. The opening team sees how many people responded and which zone they came from, instead of counting leaflets.

The offer matters more than the design. Across the eight campaigns we have completed as of October 2026, response has ranged from 3.3% to 5%, with an average of 4.2%. What moves a campaign from one end of that range to the other is the offer printed on the leaflet, so that decision deserves more time than the choice of typeface.

2. Keep the offer live for three to four weeks and track the response over time

The most common mistake at an opening is to treat the leaflet as an advert for launch day. It goes out the week before, the offer expires on Sunday and the team moves on. Paper does not work like that. A leaflet stays in the kitchen, on the hall table or pinned to the fridge, and it keeps working for weeks after the drop.

That is why the opening offer should live for three to four weeks, not three days. It is enough time for a neighbour to walk past the new store, remember the leaflet and come in with it. Close the offer earlier and you lose the part of the response that arrives late, and that part is real.

With the offer live, the response can be read over time. CARTO tracks each response with its date, so the team sees the whole curve: what arrives in the first days, what arrives in the second week and what keeps trickling in afterwards. That curve says more than the total. It shows how long paper really keeps working in that neighbourhood and when to launch the next action in the opening plan.

There is one more practical advantage. A four-week offer lets you compare the first opening with the next one under the same rules. If every new store measures its response over the same period, the chain ends up with a data series of its own, opening after opening, instead of a collection of loose impressions.

3. Split the drop into rings around the store: 500 m, 1 km, 2 km

An opening has a very clear geography. People who live five minutes away on foot come into the store out of habit; people twenty minutes away come only if there is a reason. The drop should follow that same logic rather than covering a whole municipality evenly.

We plan the print run in three rings: up to 500 metres, up to one kilometre and up to two. The inner ring is saturated first, building by building, before a single leaflet heads out to the outer rings. Then comes the second ring, then the third. The order matters. If for any reason the drop falls short, what goes missing is the edge of the two-kilometre ring, not the block across the street.

Planning runs on cadastre data, building by building, in Catalunya and in any Spanish city. Before anything is printed we already know how many mailboxes sit in each ring and which neighbourhoods fall inside it, and we can adjust the targeting by neighbourhood to match the demographic profile the store is after. If you want a feel for it yourself, the simulator shows coverage and mailboxes by neighbourhood.

And coverage is verified, not assumed. Our distributors are Brand Missionaries: employed, trained and supervised, not profiles on a gig marketplace. Every route is recorded by GPS and every zone carries geotagged photos. The opening team can open the map and see which ring is covered and which streets are still to be done.

Matching the response against the rings produces the response heat map: which zones around the store responded most and which responded least. It is measured by zone, not by counting leaflets. That map is the piece of data a chain can reuse at the next opening, because it shows the radius that actually responds to a store of that format.

4. The client dashboard is open from day one

The last play is the one that turns the other three into something the opening team can use while it is happening, not afterwards. The CARTO dashboard is open to the client from the first day of the drop, not when the campaign ends. GPS routes, geotagged photos, coverage per ring and response by zone: all in one place, updated while the team is still on the street.

That changes the relationship with the supplier. Instead of receiving two photos and an invoice, the person running the opening logs in, looks and asks questions. If a ring is moving slower than planned, they see it the same day. If one zone is responding above the others, they can strengthen the in-store offer that same week. And when it is time to justify the spend to the board, nobody has to take anyone's word for it: the data is there and it can be audited.

We never promise sales. We promise the delivery, with full transparency about where it happened, and we track the response so you can decide with data. What happens inside the store is down to the store. What happens before the door is something you can see.

If you have an opening on the calendar, this is the moment to set it up this way. There is more on how we measure paper on the blog. Request a demo and we will walk you through the dashboard on a real campaign.
