Too Long; Didn't Read
Denis Tatar was the product manager for Courier’s Preferences feature. He worked on the project for a few months as an intern at Courier. He explains how the Preferences feature's strategy wasn’t fully fleshed out. V3 of Preferences only allowed users to opt-in/out of notifications, and customers globally could also decide if certain notifications were required or not. With V4, we solved the visibility problem, which was the main “fail” from V3. V4 was a good way to strategically notify end users.
