An email alias is actually an e-mail address that shares a mailbox with a totally different email address. For instance, you can have firstname.lastname@example.org plus email@example.com and messages sent to both of them will be received in just one mailbox. This option will make it less complicated and much more convenient to control many email addresses because you will need to log in just one mailbox if you are using webmail or configure only one address in a email application on your computer. If you create an alias, you won't just have the ability to receive emails, but you will also be able to send emails from the various addresses and they'll share the Outbox, so you'll still have all communication in one location. Making use of aliases can be a substitute for using various email addresses for different purposes or forwarding one e mail address to a new one in order to control the e-mails of both in a single location.
