iOS 10 introduced a lot of smaller tweaks and features that make a big difference. One of my favorites is the one-step email list unsubscribe. This is especially useful if you signed up for something only to receive loads of spam emails with no obvious unsubscribe button at the bottom. This happened to me recently when signing up for a contest. I realized after the fact that I had also signed up to receive loads of emails from all different kinds of websites promoting something. Inbox overwhelm set in. But then I saw that beautiful unsubscribe box at the top of the page. Thank you, iOS 10. Here’s how to easily unsubscribe from email lists in Mail with iOS 10 or later.
