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 the output a candidate list rather than an answer: nothing in it 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. Write out every likely format from the name and the domain, using the common conventions.

Narrow. Addresses the company has already published show which convention it uses, which cuts a list of twenty-plus candidates down to two or three worth testing.

Verify. Run the top candidate through the 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 AI, and every new workspace starts with 14 days of Pro (up to 3 seats, 250 credits).

If you only have a LinkedIn profile rather than a company domain, start at the LinkedIn email finder, which looks the person up from the profile URL.

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, find an address the company has already published, 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 AI returns the single verified address instead, cross-checked across 25+ providers, with 98% verified work emails on our 500-lead benchmark.
