Eskimail brother 

Combination of "Eskimo brother" and "email," describing the invisible connection between you and the other person or persons out there who not only have a name similar to yours (either first and last name, or first initial and last name), but who also have already signed up for the exact email addresses that you would have preferred.

Bob Smith has many Eskimail brothers.
