## Description

Company Email Format

Find out how a company formats its business email addresses — for example {first}.{last}@acme.com — with a confidence score, so you can address outreach correctly without guessing.

What you send

- domains — up to 10 per request. Repeat the parameter or comma-separate values. Full URLs and www. prefixes are accepted.

What you get

One row per domain: the company domain, the email_domain it uses, the most common email_pattern, an example_address applied to a placeholder name (Jane Doe — never a real person), a confidence score, how many addresses the format was inferred from (emails_analyzed), and the runner-up secondary_pattern.

Good to know

- A format is only reported when it can be inferred from at least 3 known business addresses. Companies below that are listed in meta.insufficient; domains Stirista can't match are in meta.unmatched. You aren't charged when nothing is returned.
- Returns no names or email addresses of real people.

## Fields
