An e-mail alias is an e-mail that shares a mailbox with a completely different e-mail. For instance, you could have firstname.lastname@example.org plus email@example.com and e-mails sent to either one of them will be received in a single mailbox. This option will make it simpler and much more convenient to manage various e-mail addresses since you will need to log in to just one mailbox if you are using webmail as well as configure just one e-mail address in a e-mail application on your PC. When you set up an alias, you will not only have the ability to get emails, but you will also be able to send out emails from the different addresses and they will share the Outbox, so you will still have all communication in one location. Implementing aliases can be an alternative to making use of various email addresses for different purposes or forwarding a single e mail address to a different one in order to handle the communication of both in a single place.
