At a very high level, email is primarily used for discussions. With this view, successful innovation in the e-mail space requires innovation in the nature of discussions themselves. Tinkering around with better usability or feature improvements will not be sufficient to overcome the massive inertia of &#x27;traditional e-mail&#x27;.<p>We are a startup that just launched (<a href="https:&#x2F;&#x2F;tmail21.com" rel="nofollow">https:&#x2F;&#x2F;tmail21.com</a>) that aims to rethink the discussion itself. In our view, one of the major problems of e-mail (and chat for that matter) is that the discussions are not goal-oriented. So, discussions&#x2F;threads can meander around with no outcome or accountability.<p>So, we enhance the notion of discussions to be goal-oriented.<p>Now, once one has the notion of goal-oriented discussions, a natural next step is to evolve a goal-oriented discussion into a Lean Process (which is basically a goal-oriented discussion with more structure) . Examples of a Lean Process might be a Blog Article process, a Product Deployment Process, a Feature Design Process, an Issue Escalation Process etc.<p>We&#x27;ve done all this in an email-LIKE interface. I guess we&#x27;ll leave it to others to decide whether this constitutes innovation in the e-mail space :)
