Who uses the Free Email Permutator?
Teams across go-to-market rely on clean, verified data. Here is where this tool fits.
AEs & BDRs
Reach a named prospect when you have the person but not the address.
Recruiters
Construct likely candidate emails before sourcing outreach.
Founders
Email a partner, investor, or buyer you can name but can't find.
Agencies
Build outreach lists for clients from names and company domains.
How Does This Tool Work?
An email permutator takes a person's name and their company domain and generates every common email format combination at once, so you don't have to type them out by hand. com, and 20+ more permutations, each one ready to copy.
Why sales and recruiting teams use a permutator: when you know who you want to reach but not their exact email, the permutator gives you the full set of candidates in one second instead of guessing one at a time. From there you test which address is real. The catch is that only ONE of those 25+ permutations is usually the deliverable address.
Send to the wrong ones and every bounce chips away at your domain's sender reputation, which is the fastest way to land in spam for everyone on your list.
The permutator vs. the verified answer: this free tool gives you the candidates. It does not tell you which one is real, because that requires checking each address against live mail servers. That is exactly what Cleanlist does at the platform level: instead of handing you 25 guesses to test manually, Cleanlist's waterfall enrichment cross-checks 15+ data providers and returns the single verified, deliverable email for your target, plus their direct-dial phone and LinkedIn profile, at 98% accuracy.
The permutator is the free starting point; verified People Search is the answer that protects your reputation.
How to use the permutator output: copy the full list, then run the candidates through the free email verifier to find which one actually accepts mail before you send. Together the two free tools replace the slow guess-send-bounce-wait loop. Privacy note: this tool generates permutations locally in your browser from the name and domain you enter.
It does not look anyone up, store data, or send any email.

Frequently Asked Questions
What is an email permutator?
+
An email permutator is a tool that generates every common email address format for a person from their name and company domain. Instead of manually typing jane.doe@, jdoe@, jane@, and 20+ other variations, you enter the name and domain once and get the full list of candidates instantly. It's a starting point for finding someone's work email when you know who they are but not their exact address.
How do I find out which permutation is the real email?
+
The permutator gives you candidates, not confirmation. To find the deliverable one, you verify each address against the mail server. You can run the list through the free email verifier, or skip the guesswork entirely: Cleanlist's People Search returns the single verified email (plus direct dial and LinkedIn) for your target by cross-checking 15+ data providers at 98% accuracy. Guessing and sending to the wrong permutations causes bounces that damage your sender reputation.
Is this email permutator free?
+
Yes, completely free and no signup required. The tool generates permutations locally in your browser. For the verified, deliverable email behind a name (instead of a list of guesses to test), a free Cleanlist account includes 30 enrichment credits.
Why does sending to guessed emails hurt my deliverability?
+
Only one of the 25+ permutations is typically a real mailbox. The rest bounce. Mailbox providers like Google and Microsoft track your bounce rate, and once it climbs past their threshold (often 2-5%), they start routing your mail to spam for all recipients, not just the bad addresses. This is why verifying a permutation before sending matters. Cleanlist returns pre-verified addresses so you never send into a bounce.
