"I was able to make an enormous impact as the product manager for Courier's Preferences feature. The problem we experienced at Courier was that we'd offer Preferences (V3) to our customers, but the entire product feature's strategy wasn't fully fleshed out. Allowing only global opt-in/out is a problem because it constrains end users' notifications options and can lead to inbox flooding. I learned about the importance of channel and content selection through a toggle/grid style layout for preference centers, which became the backbone to our summer project. We solved the visibility problem with V4, which was the main "fail" from V3. Our customers and their end users now had the ability to control the content they received and the channels they would prefer. I worked closely with the Lifecycle team on Preferences, and everyone was so kind and offered fantastic feedback. The environment at Courier felt like working on a side project with close friends, which helped me produce great work. I learned how to prioritize tasks, stay organized, and educate others on our product vision. I also gained experience in breaking down tickets, creating a slide deck for presentations, and selling products to customers."
