Email Permutation Generator
A name and a company domain in, every address format that company might be using out. Copy the list into whatever you verify with.
What this is for
You have a name and you know where they work. You do not have an email address. Most companies use one pattern across the whole organisation, so if you can work out the pattern from any one employee, you have everybody.
The usual approach is to generate every plausible format, then run the list through a verification service that checks which ones the mail server will accept. This page handles the first half. It generates around forty variants covering the patterns that account for the overwhelming majority of corporate addresses.
How to work out the pattern faster
Before you guess, look for a known address at that company. Press releases, PDF documents on their own site, court filings, domain registration records, and job postings all leak addresses. One confirmed address tells you the pattern, and then you only need one guess instead of forty.
The Google operators page covers searching a specific domain for documents that contain an @ sign.
