My E-mail Address

Your e-mail address is especially for you to use. The e-mail address you chose cannot be assigned twice.

You can create an alias e-mail address and select it as the sender address for new e-mails. You can log in using your alias e-mail address and your password. Your e-mail address is also your user name.
