Yes, you can have multiple email accounts configured. I have 2 setup on my phone and both are appearing on the band. You can limit the emails that are shown by setting up a VIP list.
What I would like to know, is how to configure only 1 account to show up? I don't want to get email notifications from my work account on there, especially during the day when I'm receiving dozens and dozens of them throughout the day. I don't want to setup a VIP list, because I want ALL of my personal emails showing up.
