An e-mail alias is actually an email address that shares a mailbox with a completely different email address. For example, you could have firstname.lastname@example.org and email@example.com and messages sent to either one of them will be received in just one mailbox. This option will make it easier and much more convenient to control multiple email addresses because you will need to log in just one mailbox if you work with webmail or configure one single address in a e-mail app on your desktop. If you create an alias, not only will you be able to receive emails, but you will also be able to send email messages from the various addresses and they will share the Outbox, so you will have all communication in one location. Implementing aliases can be an alternative to making use of different email addresses for a variety of purposes or forwarding a single e mail address to a new one so that you can manage the emails of both in a single place.
