title: Logging properties to Serilog Email Sink
body: <p>Is there a way to configure the Serilog email sink to also include the additional properties in the email body?</p>
  
  <p>I can see the default format is:</p>
  
  <pre><code>{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}
  </code></pre>
  
  <p>But I am not sure if there is an additional token which can be used or a way in code to easily override this behaviour.</p>
