Company email formats

The email pattern at 1100 major companies, measured on 10,404 verified work emails rather than guessed from a handful of examples.

Updated October 2026

What the data shows

The most common patterns are first.last@company.com (734 companies), flast@company.com (222 companies), first_last@company.com (56 companies) and firstlast@company.com (20 companies). 15 companies have no single format, usually because staff pick their own alias. 33 use an email domain that differs from their website, so a guess at the website domain bounces.

Find verified emails

How we measure: for each company we matched 8 to 20 recently verified work emails (more where the pattern is less consistent) against each person's first and last name, and report the share of each pattern. Examples use a placeholder name. No real employee names or addresses are published.
