The company's common address formats (first.last, flast, first, firstlast, first_last, f.last) are checked one by one with the company's own mail server, and the first one it accepts is returned. No database is searched and nothing is stored. Stops early when the domain accepts every address (catch-all) and then gives the most common format as \"guess\". Each format checked counts as one verification. Personal email providers such as gmail.com are refused. Requires a paid MailTester Ninja key.",
