These addresses are format guesses. None are verified: a domain may use an entirely different scheme.
What is an email permutator?
An email permutator is a tool that generates every possible address combination from a first name, last name and company domain. It combines these elements into the most widely used formats (first.last, flast, first, last.first, and so on) to produce a list of candidate addresses you can then test.
It's a prospecting classic: when you know who you want to reach and where they work, but not their exact address, the permutator lays out the most likely guesses. What's left is figuring out which one is correct, something the tool doesn't do for you.
Every common format
first.last, flast, first_last, last.first, initials: the most common corporate schemes are covered.
One-click copy
Copy a single address or the whole list at once, ready to paste into your verification tool or CRM.
Middle name supported
Add a middle name or initial to cover the schemes used by larger companies.
Private
Everything is generated in your browser: no data is sent or stored.
How to use the email permutator
The tool works in seconds, with no install and no signup.
1. Enter the contact
Type the first name, last name and company domain (for example company.com). Add a middle name if you know it to cover more schemes.
2. Get the list of formats
The tool instantly generates every combination, with no duplicates. Each line is a candidate address in a format that's actually used inside companies.
3. Verify the candidates
Copy the list and test it with an email verifier or your sending tool to spot the right one. That step, verification, is what turns a guess into a reliable address.

Instead of guessing addresses, target the right contacts with Gojiberry
The permutator is handy for a quick fix, but it relies on trial and error: generate dozens of guesses, then test them one by one. At scale, that's time-consuming and risky for your deliverability. Gojiberry is an AI-powered, multi-channel prospecting platform: it tracks 30+ buying-intent signals across socials and the web, surfaces leads who are in-market right now, and triggers personalized outreach across channels.
Rather than guessing an address and hoping for a reply, you reach people who are already interested, at the right time and on the right channel. Fewer bounces, fewer ignored messages, more conversations that matter.
Stop guessing, start converting
Let Gojiberry spot leads who are actively searching and launch personalized outreach for you.

Best practices with an email permutator
For the generated addresses to be truly useful, a few habits matter.
Verify before you send
Never assume a combination is the right one. Run the list through an email verifier to weed out invalid addresses before any send and avoid bounces.
Confirm the name and domain
A generated address is only worth something if the first name, last name and domain are accurate. Double-check the spelling and the company's correct domain before permuting.
Don't email every combination
Emailing every candidate address is counterproductive: the wrong ones bounce and signal to mailbox providers that you're prospecting blindly. Identify the right one, then write only to that address.
Aim for relevance, not just the address
Finding the address is only half the work. Reaching someone who isn't expecting to hear from you stays ineffective. Prioritize contacts who show a real signal of interest.
Email permutator or prospecting platform?
Both help you reach a contact, but they don't play in the same league. One guesses an address, the other brings you the right people.
FAQ · email permutator
Yes, the permutator is completely free and requires no signup. You enter the name and domain, and instantly get the list of possible addresses.
No. The tool generates format guesses from the name and domain. It doesn't confirm that an address exists or that the mailbox is active. You then need to verify each candidate with a dedicated tool before sending.
No. All generation happens in your browser. Neither the name nor the domain is transmitted to a server or stored.
The first.last (mary.johnson@) and flast (mjohnson@) schemes are among the most widespread in companies, but every organization has its own rules. That's exactly why you need to verify: guessing isn't enough.
It's strongly discouraged. Wrong addresses bounce, which tells mailbox providers you're prospecting blindly and damages your sender reputation. Identify the right address, then write only to that one.
