Creating an e-mail alias means creating an e-mail that shares the same mailbox with a totally different e-mail address both for the incoming and the outbound e-mail messages. For example, you’re able to make an address firstname.lastname@example.org and it'll be connected to a unique mailbox. Then, you can create an alias email@example.com, which can use the mailbox of sales@ and does not have a mailbox of its own. Every time you look at your e-mails, you'll see emails sent to both of the two addresses in one place, which might be far more convenient in some circumstances as you will not need to log in and out of numerous email addresses using webmail or create various email addresses in an email program. This option is frequently used as a replacement for forwarding e-mail messages from one address to another if multiple email addresses are included for contact on a web site.
