Free email permutator
Enter a name and a company domain and get every address format that company is likely to use. Free, no sign-up, and nothing you type leaves your browser.
The person
Nothing is sent anywhere. The patterns are built in your browser.
Paste the full website address if it is easier — the protocol and any path are stripped.
Candidate addresses
A first name and a domain are enough. Add a last name to get the full set of personal formats.
What it generates
Ordered roughly by how common each format is in business email.
| Pattern | Example | Notes |
|---|---|---|
| first.last | The most common B2B format | |
| first | Common at small companies | |
| flast | Common in the US | |
| firstlast | No separator | |
| first_last | Underscore variant | |
| last.first | More common in Europe | |
| f.last | Initial with separator | |
| Role mailbox | Often the only published address |
Accented characters are folded to their plain equivalents and anything that is not a letter or hyphen is dropped, because mail systems rarely accept them in the local part.
Email permutator questions
A tool that takes a person's name and their company domain and writes out every address format the company might use — first.last, flast, firstlast and so on. It does not find the address; it narrows a guess from thousands of possibilities to about a dozen worth checking.
No, and no permutator can. Checking whether a mailbox exists means a server talking to that company's mail server, and this tool runs entirely in your browser — nothing you type is sent anywhere. The output is a list of candidates to verify, not a list to mail.
No. Sending to guessed addresses is one of the fastest ways to damage a sending domain: the invalid ones bounce, the bounce rate climbs, and mailbox providers start filtering the addresses that were real. Verify first, or use a source that checks addresses before handing them over.
first.last is the most common pattern in B2B, followed by flast and first on its own. Small local businesses often skip personal addresses entirely and publish only a role mailbox such as info@ or hello@, which is why this tool includes those by default.
Look for one that is already published. LeadOutreach searches Google Maps by business category and city and, for each business with a website, looks for a publicly listed email on the homepage and contact page, then runs it through syntax, disposable-domain and live mail server checks before marking it verified. That is a found address rather than a guessed one.
