An email alias is actually an email that shares a mailbox with a totally different e-mail address. For example, you could have info@domain.com as well as support@domain.com and emails sent to both of them will be received in one mailbox. This feature will make it less difficult and much more convenient to handle a lot of email addresses because you will have to log into one single mailbox if you are using webmail or create a single address in a e-mail client on your desktop. When you create an alias, not only will you be able to receive e-mails, but you'll also be able to send emails from the various addresses and they will share the Outbox, so you'll still have all communication in a single place. Using aliases is surely a replacement for working with various e-mail addresses for different purposes or forwarding one address to a new one to be able to manage the emails of both in one location.
