Prospect a French trade, not a database
Mailbase starts from the public French company register (SIRENE), where every active company carries an activity code, a place, a headcount band and a creation date. Name the trade you sell to and it finds the matches, reads their legal notice for the email and the owner, verifies the address and writes one email per person.
Artisans du BTP
Electricians, plumbers, roofers, painters and joiners: very small companies that rarely have a sales team and answer their own email.
- How the register finds them
- Construction is divisions 41 to 43 of the NAF. Filter on the trade, the département and 1 to 9 employees, and the register returns every active company with its SIREN.
- What the email can say
- Write one short email per company, built on one fact: its town, how long it has been trading, or what its own site says it does, ending on a single question.
A measured run: 145 electricians in Saône-et-Loire with 1 to 9 staff, 13 emails verified in one afternoon.

Accounting practices, from sole practitioners to regional firms, whose partners are named on the practice's own site.
- How the register finds them
- Accounting activities are NAF 69.20Z. Combine the code with a département and a headcount band to list every practice in a region.
- What the email can say
- The owner's name sits in the legal notice every French site must carry (les mentions légales), so the email can open on a person instead of a generic address.
Agences web et studios
Web agencies and software studios that resell, white-label or subcontract, and are often reached through a contact form no one reads.
- How the register finds them
- Computer programming is NAF 62.01Z and advertising agencies 73.11Z. Filter by size and age to separate a new studio from a ten-year-old agency.
- What the email can say
- Their own site is the best source: the services they list and the clients they show give one true thing to refer to.
Restaurants
Independent restaurants, where the owner is also the person who answers the phone and the inbox.
- How the register finds them
- Traditional restaurants are NAF 56.10A. Filter by town or département and by size to list the independents near a delivery route or a sales territory.
- What the email can say
- A restaurant's site usually shows its address, hours and legal notice: enough to write about the place rather than about the sender.
Commerces de détail
Independent shops, in towns where the foot traffic and the owner's name are both local.
- How the register finds them
- Retail trade is division 47 of the NAF, split by what the shop sells. Pair a code with a postal code or a département, and a headcount band.
- What the email can say
- Write about the town and the trade, name the owner when the legal notice does, and keep the ask small enough to answer in a line.
These are examples, not a menu. The register covers every sector, so any trade you can describe in plain words can be turned into activity codes: the assistant proposes them and shows you the count of matching companies before it starts. Discovery covers companies registered in France; the language of the email is yours.
Whatever the trade, the method is the same. You approve every email until you choose otherwise, a reply or a bounce stops the sequence for that company, and every message is read for scams before it leaves. Sending runs through Amazon SES from a Mailbase address or your own domain, and each domain is warmed on its own. The legal frame for B2B outreach in France is covered in the CNIL’s rules, in French.
