Unroll.me is a tool you can use to manage and declutter your inbox. Quickly unsubscribe from unwanted subscriptions or ‘“rollup” your favorite subscriptions into one email. I typically clean up my subscriptions twice per month. Rather than simply reacting to an unwanted email by deleting it, you can attack the root cause by preventing the email from ever occurring again. The bulletin: addressing root causes is how we work smarter, not harder.
