Personally I do not want my mail client to be my task manager. I use a Todo list app (Things by Cultured Code) that does a smooth job of linking a todo to an email. I simply create a task linked to an email set for 3 days from now, I delete the email from my inbox and have 1 'inbox' for my actions. I believe the various other todo apps on the mac handle this just as easily.
Seeing workflow wrapped into an email client strikes me as wrong—I want my mail client to be for communication, not for managing my next actions.
