TeamSnap has two categories for email addresses on an account: account email and roster email. The same address can be used for both categories, but they can be different. These addresses are independent, so changing one does not affect the other.
The account email is also the username to log into your TeamSnap account. It is not displayed in roster lists, only under your account settings. TeamSnap uses the account email to send you important TeamSnap news, or when there are billing issues for your account.

Roster emails are listed within each member profile on a team's roster list. Your roster email(s) is where you will receive communication from your TeamSnap team if you have the Receive Emails box checked in your roster profile.
