And yet like many of Yahoo’s products, it was overtaken in recent years by Google’s equivalent offering - Gmail now has more than 425 million monthly users. Mail is a pillar of Yahoo’s products, with more than 100 million daily users. The redesign is rolling out today simultaneously on the web, and for apps on Android, iOS, and Windows 8. The company is also putting a cap on its previously unlimited storage: 1 terabyte, which the company says should be good for 6,000 years of email. Yahoo’s march to modernize its core products continues with a significant redesign of Yahoo Mail that brings Flickr-generated themes, a new compose screen, and a host of other features designed to win back defectors.
