Log Emails Sent to DB

Question

Is it possible to log emails sent using CakeEmail using the new (2.1+) Events system?

I'm hoping I can do something like this, only what I have doesn't do anything yet:

// config/bootstrap.php
App::uses('CakeEmailRecord', 'Lib/Event');
App::uses('CakeEventManager', 'Event');
CakeEventManager::instance()->attach(new CakeEmailRecord());


 // /app/Lib/Event/CakeEmailRecord.php
  App::uses('CakeEventListener', 'Event');
  class CakeEmailRecord implements CakeEventListener {
      public function implementedEvents() {
          return array(
              'Network.CakeEmail.afterSend' => 'recordSend',
          );
      }
      public function recordSend($event) {
         $this->log("triggered an event");
      }
  }

I'm specifically asking about the events system here. I want to know if that feature is something I can & should use to solve this. The question tagged as a duplicate does not deal with the cake events system
