Email is great. It’s much faster than snail mail, and you usually get a response sooner than later. But, have you ever been writing an email wishing that you could have instant communication with your friends without picking up the phone? You can with Yahoo! Mail’s chat feature. Chat lets you and your contact exchange messages in "real time", meaning "right now", and all while using Yahoo! Mail Classic and without having to download an instant messenger application. (And it’s free!)
Your contact must have a Yahoo! ID or
a Windows Live™ Messenger ID
and must be signed in to either Yahoo! Mail, Yahoo! Messenger,
or another compatible instant messaging application. 
So, let’s just repeat the highlights and get you chatting!

You can also contact your friend by sending a mobile text message through Yahoo! Mail. To learn more, take a look at the Using Mobile Text Messaging tutorial.
Tip: If you already use Yahoo! Messenger, you might want to know more about the differences between Messenger and chat. The If You Use Yahoo! Messenger tutorial has all the details.
