An email alias is a forwarding address, meaning that all emails addressed to the alias, are forwarded to one or more specified accounts. The alias itself has no inbox, no login and cannot be used to send emails.

When is an alias useful?
As a temporary address for online use
An alias comes in handy if you need to make your email address publicly available online, for example, in a job ad or if you are trying to sell something.
The problem with having your address visible for everyone is that it will quickly become a target for spam and all kinds of other unwanted mails. By using an alias, you can have it online for as long as you need, and then simply delete it once the job is filled or your item sold.
If you fulfil more than one role
When you are starting a business, people usually fill multiple roles and departments are not clearly defined. However, you don't want to have all emails addressed to email@example.com. By creating a couple of email aliases, for the CEO, marketing and sales department, you can appear a lot more professional.
For an internal mailing list
If you maintain a mailing list, for example for your drama club, or school, using an alias will improve efficiency. You only need to send your mailing to one address, automatically forwarding it to all accounts that are added as a forwarding address. And since all forward addresses need to be verified, you can be sure they are correct.
Another advantage is that the receivers cannot see all the other addresses the mail was forwarded to, making it more private and secure.
