Guessmail 💌

guessmail helps you find possible email addresses of a person.

Usage: guessmail [-e] [-l LANGUAGE] first [middle] last domain
    -e, --extended                   Include less common email combinations
    -l, --language LANGUAGE          Set language
    -h, --help                       Shows help message
    -v, --version                    Shows version

Let's say you want to find the email address of Bill Gates.

$ guessmail Bill Gates microsoft.com  

This will return you a set of possible emails:

bill@microsoft.com
gates@microsoft.com
billgates@microsoft.com
bill.gates@microsoft.com
bgates@microsoft.com
b.gates@microsoft.com
billg@microsoft.com    <-- This is the actual email address
bill.g@microsoft.com
bg@microsoft.com
b.g@microsoft.com
gatesbill@microsoft.com
gates.bill@microsoft.com
gatesb@microsoft.com
gates.b@microsoft.com
gbill@microsoft.com
g.bill@microsoft.com
gb@microsoft.com
g.b@microsoft.com

You can then use an email verifier service or use other methods to find out which one of these email addresses belong to the person you are searching for.

guessmail can transliterate non-ASCII input since it uses tate under the hood. Try it out!
