Ok the valid email format is

[email protected]

username is usually the contact name / handle for the person you are addressing the mail to.

host is the company's server that will revieve and process the mail

.whatever is the extension url

for example.

[email protected]

kevinnobody is the person I wanna send the message to, he can be found @someserver and the ending url is .com

Hope that explains it.

No phone numbers dont have email addresses, A phoe number is similar to that of an ip address which can be seen to be similar to the comcept of a street address..

for example every computer on the internet has a unique ip address,

every line has a different phone number

every house has a different address,

This is what allows computer to interact withone another, or send info to one another. Just as your phone number allows you to call one another and your house address allows you to send mail to one another.

Your email address is similar to that of a mail box. Think of your email address as a virtual mail box, people can send virtual mail to you and you can send to them from it via the internet.

When you get an internet connection your isp assigns you email address (usually) if not you can get free ones from www.yahoo.com and www.msn.com
