As a pioneer of free email accounts Yahoo! Mail has been around for a while. The interface used to be a little bit dated but Yahoo! recently redesigned it. Yahoo! Mail is now much more faster, easier to use and better at search and spam filtering. However all those improvements have a price. To upgrade from the old interface to the new one, you have to agree to a new terms of service that grants Yahoo! the permission to scan and analyze your emails (exactly like Google does with Gmail). This is of course for targeted advertising, but also spam and malware detection.
