Me IRL, every time I look at email.
There's a new app from Unroll.me (free, iOS), that claims it's going to help me sift through all of the crap in my inbox.
Unroll.me is a website that "rolls up" all of your subscriptions/spam into a daily newsletter, so you can still sift through the sales without cluttering your inbox.
I've used the website for years and admittedly never check the rollup. The app version of Unroll.me is so much more satisfying because it forces you to actually unsubscribe instead of doing the email equivalent of putting all of your dirty clothes under the bed.
