either way is fine.

I have these two friends who I am quite fond of who run a company together and when I get email from the company email address, I never know which one I'm going to get. They each have their own email but they often write from the general one. For whatever reason I really like not knowing...and also the fact that ultimately I probably get answers from both of them - from the same account - often with cc's that make it like a big funny conversation.

I like it. For some reason I like it alot.

It's like back when people actually had land lines and you didn't know who might answer the phone.
