Free email format lookup · Read-only

Free on every plan of a signed-in account, also after the trial ends, no credits used. Works out the email format a company uses from up to 50 known contacts at that domain. Returns pattern (e.g. {first}.{last}, {f}{last}, {first}), an example with a placeholder name (jane.doe@domain), confidence (share of sampled contacts that match, as a percent string), sampledFrom and allPatterns with counts. pattern is null when there are no contacts or no recognisable format. Free tools share a limit of 10 calls per account per UTC day (resets 00:00 UTC; past it the call returns 429).
