Creating an email alias means setting up an e-mail address that shares the very same mailbox as a different e-mail address for both the incoming and the outgoing e-mail messages. For example, you are able to create an email address email@example.com and it'll be connected to its very own mailbox. After that, you can make an alias firstname.lastname@example.org, which can use the mailbox of sales@ and does not use a mailbox of its own. If you check your e-mails, you'll see emails sent to either one of the two addresses in one location, which can be far more convenient in some cases as you will not have to log in and out of different email addresses working with webmail or create various email addresses in an email program. This option is often used as an alternative to forwarding e-mail messages from one e-mail address to a different one if numerous email addresses are listed for contact on a site.
