Pardon my ignorance, but what is "unprofessional" about this? Is it the fact that "foo" is just a single word, rather than "forename surname", or is it just that "foo" on its own matches the username in "f...@example.com"? I have plenty of "professional" contacts (mainly in small businesses) where they use first names only, and also plenty of examples such as "Helpdesk <helpd...@example.com>" and "Accounts <accou...@example.com>" which are perfectly legitimate.
