Unroll.me is a handy new service that is currently in Beta which helps rid your inbox of clutter by letting you unsubscribe to emails. While there are already several ways of handling this task (filters, reporting spam, manually unsubscribing, etc), nothing handles the task as gracefully or quickly as Unroll.me. Additionally, a fantastic feature is the ability to choose which emails you do want to receive and have them arrive as a once-per-day digest.
Currently, the service works for GMail, Yahoo! Mail or AOL Mail with more providers planned for in the future. While there is currently a waiting list, read on for an instant invite.
