How to find someone’s work email

Step 1

Get the person’s full name and the company’s website domain, for example from their LinkedIn profile.

Step 2

Generate the likely formats above. Start with the top few: most companies use one of them for everyone.

Step 3

Verify the guesses with an email verifier, then send only to the address that checks out.

Tip: if you already know one colleague’s address at the same company, such as [email protected], the same pattern almost always applies to everyone there.

FAQ

What is an email permutator?

It lists the email address formats a company might use for one person, such as [email protected] or [email protected], so you can find the right one. It does not look anything up; it only combines the name and domain you enter.

Which email format is the most common?

Company addresses most often use first.last, first, flast (first initial plus last name) or firstlast. The list on this page puts these patterns first.

How do I know which address is real?

Check the guesses with an email verifier before you send anything. Mail Merge for Gmail and Sheets includes email verification and bounce detection on the Pro plan, and GPT for Sheets connects to Hunter, Prospeo and LeadMagic on the Business plan to find verified emails for a whole list.

Can I generate email formats for a whole list?

Yes. Put first names, last names and domains in Google Sheets and use the formulas on this page, such as =LOWER(A2&"."&B2&"@"&C2), then drag them down.

Is the email permutator free?

Yes, with no limit and no sign-up. Everything runs in your browser: the names and domain you type are not sent to our servers.

Is it legal to email the addresses I find?

Only contact people when you have a legitimate, relevant reason, and follow anti-spam rules such as CAN-SPAM and GDPR. Always include a clear way to opt out.
