🟢verify_email(email)
Check in real time whether an email address exists and can receive mail, by asking the recipient's mail server (no message is sent). Returns code "ok" (valid), "ko" (invalid) or "mb" (uncertain, such as a catch-all domain) with a message.

}🟢find_email(first_name, last_name, domain)
Find the work email address of a person from their name and their company domain. Tries the 6 most common patterns (first.last, flast, first, firstlast, first_last, f.last) one by one and returns the first address the mail server accepts. Stops early when the domain accepts every address (catch-all) and then gives the most common pattern as "guess". Each pattern tried counts as one verification. Personal email providers such as gmail.com are not searched. Requires a paid MailTester Ninja key.
