Email Nomenclatures

Ever wonder what are all the common email nomenclatures companies use?

I was working on a project that posed this exact question.

Here they are - 21 email address combinations:

Firstname.Lastname@domain
Firstname@domain
FLastname@domain
FirstnameL@domain
FirstnameLastname@domain
FirstnameL@domain
Firstname_Lastname@domain
LastnameF@domain
F.Lastname@domain
Firstname.L@domain
Lastname@domain
FL@domain
LF@domain
Lastname.Firstname@domain
LastnameFirstname@domain
Lastname_Firstname@domain
Lastname-F@domain
F-Lastname@domain
L.Firstname@domain
LFirstname@domain
Lastname.F@domain

-

The most popular ones appear to be:

Firstname.Lastname@domain
Firstname@domain
FLastname@domain
FirstnameL@domain
Lastname@domain
