Creating an e-mail alias means setting up an email which shares the very same mailbox as a totally different address both for the inbound and the outbound emails. For example, you’re able to make an email address email@example.com and it will be linked to its own mailbox. After that, you can create an alias firstname.lastname@example.org, that will make use of the mailbox of sales@ and will not use a mailbox of its own. Once you check your emails, you will notice e-mail messages sent to either one of the two addresses in one place, which might be more convenient in some instances because you will not need to sign in and out of various mailboxes using webmail or create multiple email addresses inside an email application. This feature is often used as a replacement for forwarding messages from one e-mail address to another if a number of email addresses are listed for contact on a website.
