 Subscribe to open and click events. Create an initializer `config/initializers/ahoy_email.rb` with:
 
 ```ruby
 class EmailSubscriber
-
   def open(event)
-    # :message and :controller keys
-    ahoy = event[:controller].ahoy
-    ahoy.track "Email opened", message_id: event[:message].id
+    # any code you want
   end
 
   def click(event)
-    # same keys as above, plus :url
-    ahoy = event[:controller].ahoy
-    ahoy.track "Email clicked", message_id: event[:message].id, url: event[:url]
+    # any code you want
   end
+end
 
+AhoyEmail.subscribers << EmailSubscriber.new
+```
+
+Here’s an example if you use [Ahoy](https://github.com/ankane/ahoy) to track visits and events:
+
+```ruby
+class EmailSubscriber
+  def open(event)
+    event[:controller].ahoy.track "Email opened", message_id: event[:message].id
+  end
+
+  def click(event)
+    event[:controller].ahoy.track "Email clicked", message_id: event[:message].id, url: event[:url]
+  end
 end
 
 AhoyEmail.subscribers << EmailSubscriber.new
 ```

+track utm_campaign: proc { |message, mailer| mailer.action_name + Time.now.year }
