An email alias is actually an e-mail that shares a mailbox with a completely different email address. For example, you can have info@domain.com plus support@domain.com and emails sent to both of them will be received in one mailbox. This option will make it simpler and more convenient to control multiple addresses because you will need to log in to one single mailbox if you are using webmail or set up only one address in a email application on your PC. If you create an alias, you will not only have the ability to receive emails, but you will also be able to send e-mails from the different addresses and they'll share the Outbox, so you will still have all communication in a single place. Working with aliases can be an alternative option to making use of various email addresses for a variety of purposes or forwarding one address to a new one in order to manage the communication of both in a single location.
