I've been using [email protected] for ages and this doesn't happen to me. Usually it's "huh that's neat", but I also have a very unique last name

Mine is [email protected]. Most just accept it (all when I visit California, maybe that's your experience?), but I do get queried about it from time to time in my home country

I have had the same experience with [email protected]. My last name is also pretty unique.

I used [email protected] and sometimes even like the op "service"@firstname.lastname.name for some time. This lead into all kinds of trouble, social and technical. Social as in people did not understand why I "owned" "service"@..., why I did not have something like [email protected]/web.de/gmx.de/googlemail.de, that a third level domain is even possible, or they did not recognize .name.

Technical trouble was almost the same: Systems did not recognise the new at the time .name or Systems had trouble with third level domains. Somstimes I could sign up, but something in the backend broke and I never received mails.

There's a 199X NYTimes article about how prestigious lastname.com is. Maybe someone can find it in the archives
