Free Email Permutator

An email permutator is a generator, not a lookup. Give it a first name, a last name, and a company domain, and it combines those three inputs into every address format that companies commonly use, then hands you the list.

The conventions it covers are the ones that account for most B2B email in practice.

Full name patterns. jane.doe@, janedoe@, jane_doe@, jane-doe@.

Initial patterns. jdoe@, j.doe@, janed@, jane.d@.

Reversed patterns. doe.jane@, doej@, d.jane@.

Single name patterns. jane@, doe@.

It queries nothing and knows nothing about the company, which is what makes it instant and free. It is also what makes it a candidate list rather than an answer: nothing in the output tells you which of the permutations exists.

You need two inputs, their name and their employer's domain, and then either a prediction or a database.

Permute. Generate every likely format from the name and the domain, which is the tool on this page.

Narrow. The email format finder shows which conventions a given company actually uses, which cuts a list of twenty-plus candidates down to two or three worth testing.

Verify. Run the top candidate through the free email verifier before you send it anything.

Or look it up. A contact database skips the whole chain and returns the verified address directly, at one credit each in Cleanlist, and every new workspace opens on Scale for 14 days with 250 credits and 3 seats, no card.

If you only have a LinkedIn profile rather than a company domain, start at the LinkedIn email finder, which reads the name out of the profile URL for you.

The permutator cannot tell you, and neither can any tool that only generates. Finding the live one means testing the candidates against the mail server that actually holds the mailbox.

Two shortcuts make that testing far cheaper. First, run the email format finder on the company domain, because most organizations use one convention across every employee, and identifying it collapses the candidate list to one. Second, check the domain has live MX records with the MX lookup, because if it does not, none of the permutations can work.

What you should not do is send to the whole list to see what sticks. Every non-existent address returns a hard bounce, and mailbox providers use your bounce rate to decide whether your mail goes to the inbox or to spam, for every recipient rather than only the bad ones. Cleanlist returns the single verified address instead, cross-checked across 25+ providers at 98% accuracy.

Enter the name. First and last, exactly as the person writes it. Accents and hyphens are worth trying both ways, since companies normalize them inconsistently.

Enter the domain. The part after the @ in the company's email, which is usually but not always the same as their website. Larger organizations often route mail through a different domain than the one their marketing site sits on.

Generate. The tool combines the inputs into the standard conventions: full name with separators, first initial with last name, first name with last initial, reversed orders, and single-name forms.

Copy. Take the whole list in one click and paste it into a verifier or a spreadsheet.

All of it runs as JavaScript in your browser. Nothing is uploaded, no lookup is performed, and there is no daily limit.

The permutator is the first step of a short chain, and each step after it removes guesses.

Check the domain. The MX lookup confirms the domain can receive mail at all. No MX records means no permutation will ever land.

Identify the convention. The email format finder shows which pattern that specific company uses, which usually reduces the candidate set to one.

Verify the survivor. The free email verifier checks syntax, DNS, and live mail servers, at 25 checks per IP per day.

Or skip the chain. Cleanlist matches the person across 25+ data providers and returns the verified email and direct-dial phone, at one credit per email and ten per phone. Every new workspace opens on Scale for 14 days with 250 credits and 3 seats, no card.

For a whole list of names rather than one person, the chain stops being practical and enrichment is the only sane route.
