If you had joe@smith.com, now that would be impressive (as I expect this domain to have been registered
decades ago). As for me, I use firstname@lastname.name (with my actual name, of course) as my primary mail address, so to me it feels normal, not tacky.
(Plus, the .name domain is also a good way of testing whether the business is stuck in the 90s - if they insist that it's still 1999 and 4-letter TLDs are a no-no, that's a red flag of sorts, especially in a technological company)
