Alto doesn't replace your inbox; rather, it gives you a unique perspective on your email. The AOL-owned Alto service first requests access to a Gmail, Yahoo Mail, AOL or .Mac account. After it analyzes your inbox, it then creates what it calls Stacks of related email that include newsletters, social network updates or messages from coworkers. You can also create your own groups for specific team members by dragging and dropping an email into a new or existing Stack.
Alto offers a valuable birds-eye view of your inbox that's unavailable via the traditional inbox view. Once email is neatly stacked, deleting email threads, alerts and spam is extremely easy. Alto isn't yet available to the general public, but you can request an invitation here. AOL says it plans to formally launch Alto later this summer.
