An email permutator is a small tool that can be surprisingly controversial.

It sits somewhere between an email address finder and an email verification tool. For many marketing and sales professionals, it’s an essential tool to help find a CEO’s email, or perhaps contact info for a new prospect they discovered on LinkedIn. To others, however, an email permutator is nothing but a waste of time.

What exactly does an email permutator do, and is it worth it? In this quick article, we’ll break down how an email permutator works and discuss whether it’s worth your time to use to find the email addresses of leads, prospects, and customers.

What is an email permutator?

An email permutator is a software tool used to find any email by name for employees at a company. It differs slightly from your usual email finder tools.

Instead of merely finding and verifying an exact address, a permutator tries to generate every possible address a person could have so you find the right one. These tools are used by marketing, sales, recruiters, and other B2B professionals to find the contact information for their campaigns, pitches, and messages.

A permutator may or may not offer email verification features.

How to use an email permutator?

Using an email permutator is super simple. There are usually no more than 3-4 text fields you need to fill out: first name, last name, nickname (optional) and company website domain.

After you fill in this information, the software will deliver email address combinations. For example, let’s say you wanted to find Elon Musk’s contact information at An email permutator would suggest things like:


A typical tool will deliver 30 to 40 address combinations! Once you have a few dozen potential emails, you can copy and paste them into your email verification tool and see which one has the highest probability of being accurate.

You may be asking: are email permutators a waste of time?

To give it to you straight—using an email permutator can sometimes be a waste of time, depending on the specific tool.

If all the tool can do is deliver a list of possible addresses, and not an actual, verified email that you need ASAP, why bother? After all, you can think of email combinations yourself, right?

Here are three good reasons you should still use an email permutator:

  1. There are an unlimited number of ways to combine a first name, last name, and nickname into an email address; without some memory superpowers, you’re unlikely to get everyone every time.
  2. Typing out dozens of possible emails takes time. Why not enter your email permutator results into Excel and upload your list directly into your email verification tool?
  3. Marketing and sales reps have usually already made their best “educated guesses” when they reach this point. If you haven’t found the address yet, let the software do it for you.
