    Email Permutator: what it does and an example result

    The free email permutator takes a first name, an optional middle name, a last name and a company domain, and lists the address formats that business is most likely to use, such as first.last@ and flast@. It cleans accents, hyphens and apostrophes and removes duplicates.

    Quick answer

    An email permutator turns a name and a domain into a list of likely addresses, such as sara@, sara.oneill@ and soneill@example.com. It only guesses: it cannot tell which address exists. Check the company's published addresses to confirm the pattern, then send one personal email, never a blast to every guess.

    What is an email permutator?

    An email permutator is a tool that combines the parts of a person's name with a company domain in the formats businesses commonly use for staff addresses. Most organisations pick one pattern, such as first.last or first initial plus last name, and apply it to everyone. If you know the pattern and the person's name, you can usually work out their address.

    The tool does not look anything up, verify mailboxes or send email. Treat the list as a set of guesses, confirm the pattern from addresses the company has published itself, and use the result only to write to one relevant person about something useful to them. Never use it to build a bulk list, and never offer money for a link that passes ranking credit: Google's spam policies list "Exchanging money for links, or posts that contain links" as link spam unless the link is qualified with rel="sponsored" or rel="nofollow".

    How do you use the Email Permutator?

    1. Type the person's first name and last name as they write it, for example on their author page. Add a middle name only if they use it.
    2. Paste the company domain or any URL on that site. The tool keeps only the domain and removes www.
    3. Read the list. The 13 core formats come first, then the separator formats and the variants for hyphenated names.
    4. Look for an address the company has published on the same domain and pick the guess that follows the same pattern.
    5. Copy that one address into your email, write a personal message, and keep a record of who you contacted and why.

    Which email formats does the tool list?

    It lists 13 core formats when a last name is given: first, first.last, firstlast, flast, f.last, firstl, first.l, last, last.first, lastfirst, lastf, last.f and the two initials. With the separator option on, it adds first_last, first-last and last_first. A middle name adds 5 more, such as first.middle.last and fmlast. Hyphenated last names are tried joined, with the hyphen kept and as the first part only, and duplicates are removed.

    How do you find out which guess is right?

    Look for evidence on the same domain before you send anything. Contact pages, press pages, author bios, PDFs and job adverts often show a real staff address, and its pattern tells you which guess to use. If you find no published address, use the site's contact form or a general editorial address instead of guessing. This tool never confirms that a mailbox exists, and sending to several guesses at once is exactly the kind of email people report as spam.

    Is it legal to email a guessed business address?

    It can be, but the rules depend on where the recipient is and what you send. In the US, the FTC's CAN-SPAM compliance guide says the law "makes no exception for business-to-business email" and requires a valid physical postal address and a clear way to opt out. In the UK, the ICO says a named work address still identifies an individual, so UK GDPR applies. This is general information, not legal advice.

    Worked example

    Example

    Example: with the default name Sara O'Neill and the URL https://www.example.com/about/, the tool keeps the domain example.com, removes the apostrophe and lists 16 addresses: 13 core formats plus 3 with an underscore or hyphen. The first four are sara@, sara.oneill@, saraoneill@ and soneill@example.com. If the company's contact page shows a colleague's address in the first.last pattern, the one to use is sara.oneill@example.com. For José Luis García-López at example.co.uk, the list grows to 53 addresses across 3 spellings of the last name.

    Frequently asked questions

    Does the tool check whether an address exists?

    No. It only combines name parts with the domain. It makes no network requests, so it cannot check mail servers or mailboxes. Confirm the pattern from an address the company has published, or use the contact route the site offers.

    Should I email every address in the list?

    No. Sending the same message to many guesses lands in the inboxes of strangers, looks like spam and can hurt your sending reputation. Pick the one address that matches the company's published pattern and send a single personal email.

    Why does the tool remove accents from names?

    Company mail systems usually build addresses from plain a to z letters, so José becomes jose. Some systems do support accented addresses. If the person's published address keeps the accent, copy it exactly instead of using the guess.

    How are names like O'Neill or García-López handled?

    Apostrophes are removed, so O'Neill becomes oneill. Hyphenated last names are tried three ways: joined, with the hyphen kept and as the first part only. Every spelling goes through the same formats and duplicates are removed.

    Do privacy laws apply to work email addresses?

    Often, yes. The UK ICO says a work address that names a person identifies an individual, so UK GDPR applies. US CAN-SPAM covers commercial email with no business to business exception. Identify yourself honestly and honour opt-out requests.

    Are the names I type stored anywhere?

    No. The permutator runs entirely in your browser with JavaScript. Names and domains are not uploaded, logged or saved, and nothing is sent to the people or companies you type.
