Lists the formats
About twenty addresses from the name and domain, in the order companies use them, with accents and double surnames handled.
Checks the likely ones
Asks their mail server about the top eight, one at a time, and stops at the first it accepts. Nothing is sent.
Searches when checking can't tell
A domain that accepts every address can't be checked, so we search for theirs instead, and say so when that finds nothing.
Questions
What is an email permutator?
A tool that lists the addresses a company is likely to have given someone, from their first name, last name and the company's domain: jane.doe@, jdoe@, jane@ and so on. Most companies pick one format for everyone, so one of the first few is usually right.
Which email format is most common?
first.last@ (jane.doe@) is the most common at companies, followed by first@ at small ones and flast@ (jdoe@) at older and larger ones. The list is in that order. If you know someone else's address at the company, their format is the best clue to everyone's.
How do I know which address is the real one?
Press Find the real one. We ask their company's mail server about each address, most likely first, without sending an email, and stop at the first it accepts. Addresses it refuses are crossed out.
What if the company's mail server accepts every address?
Many large companies' servers do, so they say yes to all the guesses alike; these are called catch-all domains. When we meet one, we stop checking and search for the person's address instead, and show it if it passes our deliverability checks. Some servers also answer only to senders they know; those addresses are marked with a question mark.
Can I just email every address on the list?
Don't. Only one is real, so the rest bounce, and bounces tell inbox providers you mail addresses you don't know, which sends your future email to spam. Check first, then send to the one that's accepted.
Does it handle accents, hyphens and double surnames?
Yes. Accents are dropped the way company mail systems drop them (José Müller becomes jose.muller), apostrophes are removed, and a double or hyphenated surname adds variants with each part, like maria.garcia@ and maria.lopez@, below the main list.
Is it free?
Yes. The list is free with no sign-up. Checking which address is real costs us money for each address, so it needs a sign-in with your email, using a code rather than a password, and gives you 40 address checks a day.
