Here are some of the freshest and best:

• Unlimited Storage. Hard to imagine, like the universe. Unending. Infinite!
• Chat...In mail! That’s right – if you’re writing anyone who’s online with Yahoo! Mail or Messenger, you can contact them instantly if you like.
• Use extended navigation to steer from message to message in a thread, or from one message to another from the same sender, or from one flagged message to the next, or from one unread to the next unread.
• Get today’s weather for your area (or any location) in the upper-right corner of the Home tab – the first page you see when you sign into Yahoo! Mail.
• Stay on track with a calendar timeline at the bottom of your Mail window.
• Drag and drop messages into folders for easy organising.
• Or use Check-boxes. They’re back! Along with the Move button. Move stuff!
• Search for messages containing any word or phrase you want to find with the new super-fast and comprehensive search tool, and improve the precision of your results with search shortcuts.
• Open multiple messages in tabs so you can multitask.
• Read and manage your messages easily with the Reading Pane.
• Work keyboard shortcuts like “n” for a new message or “r” to Reply.
• Navigate from message to message with your arrow keys.

Yahoo! Mail works like a desktop application.

But unlike your desktop, it's accessible to you from any Internet-connected computer in the world! Yahoo!
