Yahoo has launched an enhanced version of its Mail service. The changes to Yahoo Mail offer users a “smarter in-box” experience that the company said it will roll out gradually to its users during the coming months. The move is part of its ongoing Yahoo Open Strategy initiative. As the change expands across all regions, Yahoo Mail users will find a new “Welcome Page” that will include messages, information and activity updates from people users have identified as important as well as an updated in-box and folder view that filters messages from personal connections.
