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