Making an e-mail alias means creating an e-mail address that shares the same mailbox with a completely different address for both the inbound and the outbound e-mail messages. For instance, you are able to make an e-mail address email@example.com and it'll be linked to a unique mailbox. Next, you can create an alias firstname.lastname@example.org, which will use the mailbox of sales@ and won't use a mailbox of its own. If you look at your email messages, you will notice email messages sent to either one of the two email addresses in a single place, which might be far more convenient in some circumstances because you will not have to sign in and out of numerous mailboxes using webmail or configure many addresses inside an email application. This feature can be used as an alternative to forwarding email messages from one e-mail address to another if numerous addresses are listed for contact on a web site.
