Company email formats

{first}.{last} — [email protected] — is the one most organisations use, with {first} and {f}{last} the common alternatives. The only way to know for a specific company is to look at addresses it has published itself, which is what the pattern finder does.

From addresses the company publishes where the person's name is also known. [email protected] belonging to Jane Doe is one vote for {first}.{last}. Confidence comes from agreement and sample size, and a local part matching several templates splits its vote so one ambiguous sample cannot outweigh a clear one.

Enter the domain on its page here and the tool reports the template, how many published addresses it was inferred from, and how much they agreed. Each page also shows the company's MX records, mail provider, SPF and DMARC policy, read directly from DNS with the date they were read.

Because the company publishes too few addresses with names attached for a pattern to mean anything. Reporting one from a single sample would be presenting a guess as a finding. The DNS facts on the page are unaffected — those are read directly from the domain.
