I use a .xyz domain for my personal email, and I sort of regret it.

My emails have a tendency to become spam filter bycatch, to the point that when I was job hunting last year I'd have to ring people after I sent them my resumes etc. to confirm they actually received my email.

And when I give people my email address, I usually have to assure them that steve@stevetech.xyz is a legitimate email address and not a joke (it's not actually steve, but you get the point).
