1) Email allows users to send electronic messages to other users via the internet. To set up an email account, users select a username and password and provide basic contact information.
2) Once the account is set up, users can access their email by logging into their account online. They can then view, reply to, forward, delete or compose new messages from their inbox.
3) The address book feature allows users to store contact information for easy emailing. Users can also mark emails as read, unread, flagged or spam. It is important for security that users always sign out of their email account when finished.
