What’s their email format?
Read off real addresses instead of guessed — from 7.5M+ verified US business records.
How do you find a company's email format?
The reliable way is to look at addresses that already exist at that domain and compare each to the person’s real name. If the addresses on file at a company consistently read first.last@company.com, that is the convention — observed rather than assumed. The common alternative is to generate candidate addresses and probe them by SMTP, which is slow, frequently blocked, and visible to the recipient’s mail server. This tool takes the first approach against 7.5M+ verified records, reports how many addresses support the pattern it found, and says plainly when the sample is too small to be sure.
Questions
How does this work without guessing?
It reads addresses we already hold at that domain and compares each one to the person's actual first and last name. If forty addresses all look like first.last@, that is the convention — observed, not assumed. Most tools generate candidate addresses and test them by SMTP, which is slow, unreliable and visible to the recipient's mail server.
Why does it say 'moderate' or 'low' confidence?
Because one matching address proves very little — plenty of people have an address that happens to fit a pattern by coincidence. Two is a weak signal and several is a genuine convention. Saying which is the difference between a tool and a confident guess, so the confidence is always shown.
Will it show me the actual email addresses?
No. It reports the pattern and how many addresses support it. The addresses themselves need a free account, which unlocks 50 leads a day with no card. Handing over the mailboxes here would make this a scraping endpoint rather than a tool.
What if it finds nothing for my domain?
Either we hold no addresses there, or none of the ones we hold match a recognisable convention — some companies genuinely do not use one. A blank result is a gap in the data or an absence of pattern, never proof that an address does not exist.
Is a pattern enough to email someone?
It is a strong start, not a guarantee. People leave, duplicates get suffixes, and some companies run more than one convention at once — which is why any second and third pattern found is shown too. Verify before you send; a bounce costs more than a check.
