title: Sending bulk notification emails without blocking
body: <p>For my client's custom-built CRM, I want users (technicians) to be notified of changes to marked cases via email.</p>
  
  <p>This warrants a simple subscription mapping table between users and cases and automated emails to be sent every time a change is made to a case from within the logging method.</p>
  
  <p>How do I send 10-100 emails to subscribed users without bogging down my logging method? My SMTP server is on a peer on my LAN, so sends should be quick, but ideally this should be handled by an external queuing process.</p>
  
  <p>I can have a cron job send any outstanding emails every 10 minutes, but for this specific client cases are quite time-sensitive and instant notification (as instant as email can be) would be great.</p>
  
  <p>How can I send bulk notification emails from within ASP.NET MVC without bogging down my logging method?</p>
