Knowing the format is step 1. Step 2 is verifying that the resulting address actually delivers — both happen inside HuntMeLeads in the same flow.

The other 19% is split across 25+ less-common patterns.
Even a 90%-confidence format misses ~10% of employees. Founders with vanity addresses, acquired teams keeping legacy domains, contractors on consultant aliases — all live outside the dominant pattern. The fix is permutate + verify, which HuntMeLeads runs automatically.
Look for these flags: post-acquisition (Acme buys Beta, Beta employees keep first@beta.com routed to first.last@acme.com), rebrand (formerly @oldname.com still accepts), or enterprise with regional subsidiaries. The format finder returns all active patterns with usage %.
Pull the format → permutate name + format → verify → send. Or skip all three and just use the email finder, which runs the loop in one API call and returns only the deliverable address.
