That is entirely possible :-).
Except for the small
minority of users who switch MUAs back and forth (see below),
FWIW, this is not a small minority any more. A fair number of people own and
use multiple mobile devices and access their email from all of them.
I can't emphasize this enough. Everyone in my family from my 20 year
old daugher to my 95 year old father has both a computer (usually a
laptop) and a phone, and reads and sends mail from both. I'd say that
multiple devices have become the norm, so if want to use your mail in
a sane way, you need to use IMAP or something else that manages a
server mail store shared by all the clients.
