How it works

From your go-ahead to the first results

1

You tell us who to reach

Four ways, your choice: describe what you sell and we propose the target; give us the exact target; give us your best clients and we find lookalikes; or bring your list and we confirm the addresses.

2

You approve the list and 10 real letters

Within 48 hours you get the company list and ten real letters, with your logo and signature. Approve, ask for changes, or let them go.

3

We print, envelope and post

One letter per company, machine-folded and enveloped, franked and handed to the postal service. They go out in about 5 business days.

4

You get the proof and the replies

Proof of posting with date and quantity, and the final list. Replies reach your inbox and phone over the following weeks.

In the name of honesty

A letter is the most expensive channel per contact: about €1.90 against two cents for an email. And it's slow, because replies arrive over two to four weeks. That's why it only pays off if you sell value: consulting, business software, professional services, industry, commercial real estate, brokerage. If you sell something for €200 you'll prefer email; if you earn €3,000 or more per client, the maths changes. And, as with any prospecting, we don't promise a reply rate: in well-targeted B2B mail, typically 0.5% to 2% of companies reply.

Frequently asked questions

What people ask us about this solution

Why letters, when everyone uses email?

Exactly because of that. There's no algorithm between your letter and the desk of whoever decides: a letter addressed to the Board gets opened, by the person or by the assistant who hands them the post. Email closes and disappears; a letter stays on the desk and goes into Monday's meeting.

Is someone who replies to a letter different from someone who replies to an email?

They are. Replying to a letter takes more effort than clicking “reply”, so fewer people reply, and those who do have already decided it's worth it. Fewer contacts, far warmer.

Is each letter really different?

Yes. The argument that convinces the director of a metal workshop isn't the one that convinces the manager of a consultancy. We generate each letter's copy from your approved template and that company's data. Before printing, you read ten real letters.

Does the letter go out in my company's name?

From start to finish. Logo in the header, your signature at the end, your contact details for replies and your name on the envelope. Whoever reads it doesn't know we exist.

Is this legal everywhere?

Physical mail addressed to businesses is the least regulated prospecting channel there is, in the EU and beyond: no prior consent and no blocking lists. What we do in Lisbon we do in Paris or Munich without changing a step.

What about annoyed companies?

In thousands of letters sent we have never received a single removal request. A cold email irritates and a cold call interrupts; a letter waits for the moment the person decides to open it.

How long until it's in the post?

About a week between your approval and posting: 48 hours for the list and samples, and 5 business days to produce and hand over to the postal service.
