    How Email Pattern Discovery Works

    When we have public email samples for a domain, we show the observed naming format and the sample count. For domains without samples, we show a common format as an unverified starting point.

    Frequently Asked Questions

    How do you detect email patterns?▾

    When we have stored public email samples for a domain, we summarize the observed format and show the sample count. Otherwise, we show an unverified starting format.

    How accurate is the email pattern?▾

    Accuracy depends on the number of samples we've collected. A suggested format with no samples is not verified for that domain. Check the sample count and confirm a format before relying on it.

    Can I use this to find someone's email?▾

    This tool shows the email naming pattern (e.g., first.last@company.com), not individual email addresses. Combine the pattern with a person's name to construct likely email addresses. A naming pattern does not verify a person's address.

    What's the most common email format?▾

    Companies use several formats, including first.last@company.com, flast@company.com, and first@company.com. The format for a specific domain needs evidence.
