How to find the right address
- Check the company website: contact pages, press releases and team pages often show one real address that reveals the pattern.
- Look at public profiles, conference talks or published papers where the person lists an address.
- Run the top candidates through an email validator to confirm the domain accepts mail.
- When unsure, use the company's general contact form instead of guessing repeatedly.
Frequently asked questions
What is an email permutator?
An email permutator combines a person's first name, last name and initials with a company domain to list the address formats a company is likely to use, such as jane.doe@, jdoe@ or janed@. It helps you guess an address when you know the name and company.
What is the most common business email format?
first.last@domain ([email protected]) is one of the most widely used formats, followed by patterns such as firstlast, flast (first initial plus last name), first only and firstl. Practices vary by company size and email system.
Does this tool check if an address exists?
No. It only generates candidates and never sends anything. You can check the syntax and domain mail records with the Email Validator on this site, or look for the company's format on its website or in a signature.
How are accents and hyphens handled?
With the clean option on, accents are removed and the name is lowercased, so José becomes jose, and spaces, hyphens and apostrophes are dropped, so O'Neil becomes oneil. Most mail systems only allow plain letters and digits in names.
Is it OK to email addresses found this way?
Use the results responsibly. Send relevant, personal messages, identify yourself, offer a way to opt out and follow anti-spam laws such as CAN-SPAM in the US and the GDPR where it applies. Never use the list for bulk unsolicited mail.
Can I generate patterns for several domains?
Yes. Separate domains with commas, for example example.com, example.co.uk. Every pattern is generated for each domain, up to 10 domains.
