Congrats on shipping an MVP! In my humble opinion however Kanban and email are not a match. In fact for most people (definitely for me) I believe email is a very poor backend for a todo list. My reasoning is that your email inbox is something that anybody can add items to -- even if those items start out as uncategorized, you still need to decide whether they deserve action or not. And when you receive 100+ emails a day, that's a job in and of itself. The essence of any prioritization system should be that it helps you focus on the most important things first. And you already know what those things are -- you don't need dozens of people proposing them to you. My personal system is to sit down every Monday morning, think about the absolute highest impact things I need to accomplish that week, and write them down in an old fashioned paper notebook which I refer back to any time I feel like I'm spinning my wheels. Fundamentally the value I generate doesn't come from reacting to people all day, it comes from identifying outcomes that truly matter and doing whatever is necessary to advance those outcomes. There absolutely are jobs where the inbox-as-todo model makes sense: customer service agent and certain kinds of sales rep come immediately to mind. But I think this model where externals just keep on pushing new tasks onto you is fundamentally not a great tool to help most people generate value. Also not good for mental health. If you have a boss, a personal assistant, a spouse or kids those are people who should probably be able to reach you immediately and easily. Outside of that I think we should generally start at zero and have to whitelist specific people. In the old days this was accomplished by giving them your phone number.
