I&#x27;ve been using Inbox for Gmail ( <a href="https:&#x2F;&#x2F;inbox.google.com" rel="nofollow">https:&#x2F;&#x2F;inbox.google.com</a> ) since launch and it handles most of the things the author talks about.  Emails are treated as tasks, and it&#x27;s a single mouse click or keyboard shortcut to do any of the following: create a reminder based on a given email, pin it for easier later retrieval, or archive it.  That&#x27;s basically how I manage my mail, along with a simple trick from &quot;Getting Things Done&quot; (which I haven&#x27;t read), which is that if a task is only going to take a short time, do it immediately rather than putting it off.
