Guess the email
like a pro

You know the name and the company — the address is one of about fourteen patterns. Generate them ordered by how common each one really is, then verify before you send.

Questions, answered honestly

How do I know which permutation is the real address?

Verify before you send. Run the top candidates through an email verification service (or our free checker for the structural part), look at how the company formats addresses in press releases and LinkedIn exports, and prefer the patterns at the top of the list — they're ordered by real-world frequency.

Can't I just email all 14 permutations?

Please don't. Most will hard-bounce, and a burst of bounces from your domain to one company is exactly the signal that gets future email — including the one to the right address — filtered. Some companies also use catch-all addresses, so you'd hit several 'valid' inboxes and look like a spammer to the one human reading them.

Which pattern is most common in B2B?

first.last@ dominates — roughly half of companies use it as the default. first@ is common at startups under ~20 people, f.last@ and flast@ at older or larger companies. That's the ordering the tool uses.

What does the MX check tell me?

Whether the domain can receive email at all. If MX records are missing, every permutation is dead on arrival — usually it means you have the wrong domain (the company sends from a different one) or a typo.

What about accents and middle names?

Accented characters are transliterated automatically (José → jose) since email locals are ASCII in practice. For middle names, try the tool with and without — but they're rare in addresses outside of very large organizations.

Find them here. Reach them safely.

Norbelys verifies addresses on import and suppresses bounces automatically across campaigns — so prospecting experiments never cost you your sender reputation.
