Creating an email alias means creating an email address that shares the very same mailbox with a completely different address both for the incoming and the outbound email messages. For example, you can make an e-mail address [email protected] and it will be associated with its own mailbox. After that, you can create an alias [email protected], which can make use of the mailbox of sales@ and won't use a mailbox of its own. When you look at your e-mails, you'll see emails sent to both of the two email addresses in one place, which may be more convenient in some circumstances as you will not have to sign in and out of numerous email addresses using webmail or set up multiple addresses inside an email program. This feature can be used as an alternative choice to forwarding emails from one address to a new one if a number of email addresses are listed for contact on a website.
