Once you have read a message, you have the option of deleting it or moving it to a certain folder. You may store as many messages as you like as long as you do not go over your e-mail service's storage limits. All messages in your account are stored on their servers, NOT on your own computer. You can also print messages. Open the message and then use the print function of your browser found in the File menu or on the toolbar.
Many web based email services have address books.
The address book makes it easy to recall the email addresses of your friends or groups of colleagues by using nicknames. You can add addresses by going manually to your address book by clicking on it. Many web based email services also allow you to save address when someone writes you an email. To write a letter to someone in your address book you can click on your address book and click on their name or in some services you can click on to addresses when you are in the compose screen. This is a much faster and effective way to enter an email address.
