title: Using NServiceBus and EventStore from High Level
body: <p>So I've been reading about EventStore and NServiceBus and I like the idea of having a transactional log of my data that can help me build views based on that data.</p>
  
  <p>What I don't understand right now is how to distinguish between an event that will write to your read storage and the same event which might trigger an email to get sent.</p>
  
  <p>ex. Creating a customer</p>
  
  <pre><code>CreateUserCommand -&gt; CreateUserCommandHandler -&gt; CreatedUserEvent
  </code></pre>
  
  <p>Should I be using the CreatedUserEvent to trigger both my write to my data storage and sending an email to a user?</p>
