Email format
The pattern a company uses to build employee addresses (first.last, initial+last, etc.).
Most companies apply a single pattern to all their addresses: first.last@domain, f.last@domain, firstlast@domain… Knowing the pattern lets you infer an employee's address from their name and the company domain.
The format is inferred from actually observed addresses: the larger the sample, the more reliable the estimate. An inferred address is still a hypothesis — it must be verified before any send.
