We constantly listen to feedback from our users with the goal of providing the best Web mail experience available,

This beta gives people a faster and more dynamic way to experience Yahoo Mail.

Yahoo is not planning to require payments for businesses or organizations to send e-mail to Yahoo users. Companies can continue to send e-mail to Yahoo e-mail users at no cost in exactly the same way they always have.

It's a really fast experience moving through your e-mail. While you are composing one message, you can click on the 'inbox' tab and go into your inbox to read another message.

We are limiting the scope to transactional e-mails, which we define as bank statements or purchase receipts where our users have a pre-existing relationship with that sender.

Yahoo's intention is to make the new version generally available to all users worldwide after the company has completed beta testing.
