I would not. Hubs knows my email password and I know his, but I'd never have a shared one. I don't know why - I find the concept weird. BIL and his wife have one and as if it's not enough for them to live together, work together and literally be together 24/7, they share email too and don't have their own.

I get it if you have one for like...gathering wedding rsvps or something like that, but normal, everyday use?
