Deleting an email account from your Fire is simple:
- Open the Quick Settings panel, and tap the Settings icon (or tap the Settings icon in the Carousel if it is there).
- Tap My Accounts, and then tap Manage Email Accounts.
- All your accounts are listed under the Accounts heading. Tap the one you want to delete.
Scroll down to the Remove Account section, and tap Delete Account from Device (4.8).
4.8 Deleting an account is easy. Just the data on your phone is deleted.
- Tap OK.
The account has been removed, though all of the information associated with that account is still available on your provider’s servers (unless this is a POP account that’s set to delete email from the server).
