# What is an email alias?
Last updated: 15/08/18 at 20:39
An email alias is a secondary email address that is bound to a primary email address. It is not a separate mailbox, as all messages sent to it will be delivered to the primary email address.
The email account firstname.lastname@example.org is a primary mailbox, with an alias email@example.com. All mail sent to firstname.lastname@example.org will be received in John's inbox. When John replies to one of these messages, it will show as being sent from email@example.com.
You can have up to 9 alias addresses per mailbox at no extra cost.
Email aliases can be setup through your administrative control panel by going to https://manage.cloudplatform1.com and signing in with your email address and password.
