If you use a Gmail account frequently, you definatly have realised about the benefits of being able to IM quickly, it seems to work well with its integration on email. Yahoo is also going to be adding this to their email services as well.

Yahoo! Instant Messenger will be built inside of Yahoo!’s free email service so users can chat and see when contacts are online.

Yahoo has the largest free email user base which sits at about 250 million users, while Google’s Gmail sits at the bottom with 51 million users. Supposedly the integration could be any day now for users that log into the Yahoo! Mail beta. Michael Arrington from techcrunch.com has seen the new beta and he has reports that each new IM can be triggered when users are online, popping up in a new tab within Yahoo email.
