Is email really comparable ? The todo examples quoted were self assigned tasks, emails are usually things you need to do for other people. I can get on board with the email task management, creating personal to-do lists is just not my style.
OP here. When I compare email to, for example, being an IC and using JIRA/Trello, there seems to be a natural analogy in that there's an inbox of items you have to respond to.
And more power to you for knowing what works for you and what doesn't. I found that to-do lists work for me, and I'm glad you know what works for you.
