title: Continues Integration through email approval in TFS release definition
body: <p>I'm using Microsoft Visual Studio Team Foundation Server
  Version 14.102.25423.0</p>
  
  <p>As part of our company's continues integration deployment,
  I want to implement the following:
  I have created a release definition with two environments configured under it (QA &amp; Production).</p>
  
  <p>I want to receive an email when all the tasks in the QA environment are completed <strong>successfully</strong>.
  In that email there should be a button that once pressed, the Production tasks will start.</p>
  
  <p>I would love to hear any ideas how do I implement this.
  All I've found so far are build alerts and not release alerts.</p>
  
  <p>Thanks,
  Much appreciated.</p>
