How it works

The tool matches the domain you enter against a database of company email formats, inferred from observed address patterns, and returns the dominant format along with its breakdown.

1

Enter the domain

Type the company's domain (for example company.com).

2

Read the dominant format

Get the most common pattern (first.last, f.last…) and the share of other observed formats.

3

Build then verify

Apply the format to your contact's name, then verify the address before sending.

Frequently asked questions

How do I find a company's email format?

Enter the company's domain: the tool returns the most common address pattern (first.last, f.last, etc.) estimated from addresses actually observed on that domain.

Where does this data come from?

The format is inferred from aggregated address patterns. No real address or name is shown — the example uses a fictitious name.

Why isn't my domain found?

The database mainly covers French companies. If the domain is missing, use the email permutator to generate the most likely formats.

Is the format guaranteed?

No, it's an estimate. To get a contact's exact address, use the email verifier or Listar enrichment.

From the format to your contacts' exact address

Listar finds and verifies your contacts' real professional email by querying 30+ sources, with deliverability validation.
