Making an email alias means setting up an email address which shares the very same mailbox as a completely different e-mail address both for the inbound as well as the outgoing e-mail messages. For instance, you’re able to make an address firstname.lastname@example.org and it will be connected to its own mailbox. Then, you can create an alias email@example.com, that will make use of the mailbox of sales@ and won't have a mailbox of its own. When you check your email messages, you will see e-mail messages sent to both of the two addresses in a single place, which might be far more convenient in some cases because you will not have to sign in and out of various mailboxes working with webmail or create multiple email addresses in an email app. This option is frequently used as a replacement for forwarding email messages from a single address to a new one if numerous addresses are listed for contact on a site.
