Highlights of the Yahoo! Mail beta include a sleek, easy-to-use interface with the speed and responsiveness of a desktop application.

The latest version also features innovative online calendar integration and provides a fast, efficient experience with enhanced functionality, such as drag and drop e-mail organization, message preview and an integrated RSS reader.

The beta is now being rolled out to Yahoo! Mail users in the United States, Australia/New Zealand, Brazil, China, Hong Kong, India, Italy, The Philippines, Singapore, Spain, and Taiwan. In addition, Yahoo! has introduced a localized French-language version in Canada, as well as an English-language version in Asia. Earlier this year, the beta was introduced in the United Kingdom, Ireland, France, Germany, Canada and Korea, and with this latest global expansion, the beta is now open and localized for people in 18 markets around the world.

In addition to its efficient user interface, the latest version of Yahoo! Mail also features an all-new integrated calendar timeline, making it easier for people to organize their schedules from within their Web mail, without having to click on a separate view or open another browser window. Upon creating a new Yahoo! Mail account, or signing in to an existing account, users will have the option to try the new interface, and will be able to toggle between the different versions of Yahoo! Mail. As with the current free version of Yahoo! Mail, users of the beta will have access to Yahoo! Customer Care to receive help in addressing technical support needs.
