-## Tagging your deliveries
+## Tracking opens and tagging your deliveries
 
 You can use tags to categorize outgoing messages and attach application-specific information. Tagging the different types of email that you send lets you [review statistics and bounce reports separately](http://developer.postmarkapp.com/developer-build.html#message-format).
 
+Pass `:track_opens => 'true'` to enable/disable open tracking on per-message basis. Check out the [Triggers API](https://github.com/wildbit/postmark-gem/wiki/The-Triggers-API-Support) to see how Postmark can help you control this with tags. **Note that we pass a string here, since it becomes a header value. Passing a boolean may or may not work depending on your Rails version.**

 class TestMailer < ActionMailer::Base

     mail(
       :subject => 'hello',
