Results
An email permutator builds every plausible email address for a person from their name and their company domain. Most companies follow a predictable pattern such as first.last@company.com or flast@company.com, so generating the full list of combinations is the fastest way to guess a professional address. Copy the list, drop it into your outreach spreadsheet, and verify the addresses before you hit send.

Frequently asked questions
What is an email permutator?
An email permutator is a tool that combines a person's first name, last name, and company domain into every common email address format. Since most organizations assign addresses using a standard pattern, one of the generated combinations is very likely to be the real address.
Which email format do most companies use?
The most common corporate formats are first.last@company.com, first@company.com, and flast@company.com. Larger companies tend to use first.last to avoid collisions between employees, while startups often use just the first name.
How do I know which generated address is the right one?
Run the list through an email verification step before sending anything. You can check the domain's MX records, look at the address format the company uses publicly on its website, or send a single test message. Sending to all combinations at once hurts your sender reputation.
Is it legal to guess someone's professional email address?
Generating combinations of publicly known information is legal in most places, but what you send matters. Commercial outreach must follow laws like CAN-SPAM and GDPR, so include an unsubscribe option, identify yourself honestly, and respect opt-outs.
Does this tool store the names or domains I enter?
No. Everything runs in your browser and nothing you type is sent to our servers. You can even disconnect from the internet after the page loads and the generator keeps working.
How do I email a whole list of addresses at once?
Paste your verified addresses into a Google Sheet and use Mail Merge for Gmail to send each person an individual, personalized email. Every recipient gets their own message, so it looks hand-written instead of a mass blast.
