# Email permutator: find the likely email address for anyone at a company

Type a name and a company domain. You get every common email format, ordered from most to least likely, ready to verify.

First nameMiddle name (optional)Last nameCompany domain

Type a first name and a domain to see the likely addresses.

## How the email permutator works

Most companies build every address from the same pattern. Once you know a person's name and the company's domain, there are only about twenty realistic formats. The tool writes them all out, plus the role addresses small businesses use most (info@, hello@, office@), so you can test them instead of guessing.

## Why the order matters

The list is sorted by how often each format appears in practice. For a two-person plumbing company, `maria@` or `info@` is far more likely than `lopez.m@`. For a 200-person firm, `maria.lopez@` or `mlopez@` usually wins. Start at the top and stop at the first address that verifies.

## Never send to a guess: verify first

A permutation is a hypothesis, not an address. Before you email one, check it: look up the domain's mail servers (our [email domain checker](https://leadraft.co/tools/email-domain-checker) does that), then ask the server whether the mailbox exists. Three things can happen:

-   **Verified:** the server confirmed the mailbox. Use it.
-   **Accept-all (catch-all):** the server says yes to every address, so the check proves nothing. Every permutation will "pass". Read [catch-all emails explained](https://leadraft.co/blog/catch-all-emails-explained) before sending to these.
-   **Invalid:** no such mailbox. Try the next format.

## A better source than guessing

For local businesses, the real address is usually published on the business's own website: the contact page, the footer, the privacy policy. That's where Leadraft looks first. It reads each business's own site, keeps up to five addresses with their role and the page they came from, and checks every one against the live mail server. Permutations are the fallback when a site lists no address at all.

## Questions

What is an email permutator?

A tool that combines a person's first name, last name and company domain into every common email format (maria@, maria.lopez@, mlopez@ and so on), so you can test which one is real.

Which email format is most common?

At small, owner-run businesses the first name alone (maria@) and role addresses (info@, office@) are very common. Larger companies tend to use first.last@ or first initial plus last name. The only way to know for one company is to check a known address there or verify the candidates.

How do I know which permutation is right?

Verify the candidates with a mailbox check, one at a time. A Verified result means the mail server confirmed the mailbox. If the domain is catch-all, every candidate will look valid, so a check can't pick one: look for the address on the company's website instead.

Is this tool free? Do you store what I type?

It's free and runs entirely in your browser. Nothing you type is sent to us or stored.

Should I email every permutation?

No. Sending to guessed addresses produces bounces, which hurt your sender reputation. Verify first and send only to addresses that pass.
