What is an Email Address?
An email address is a unique internet address for sending email. When you join with Optus you will be assigned one email address, and you have the option of setting up a total of five. Your email address may have been referred to as your username. An email address has two main parts; the username and the domain.
The above example has the username 'jbloggs'. The username identifies the Optus mail box, similar to how a street number identifies a house.
The domain or host name is the name of your ISP. This identifies the origin of the person sending the email, similar to how a street name, suburb and state identifies the national location of a house.
The two-letter country code identifies the country in which the email address is registered, for example .au means Australia, .uk means The United Kingdom.
Each email address is unique and must be used exactly as given - adding spaces, dots or other characters may cause an email to be sent to a different person than it was intended.
