title: Update confirmation email on the event checkout_onepage_controller_success_action
body: <p>I’m facing an issue and i’m wondering if you could help me with it ..</p>
  
  <p>I need to update my confirmation email on the following event:  checkout_onepage_controller_success_action, and send it only after my updates are done inside it.. </p>
  
  <p>Problem is I don’t find where is sent the confirmation email in the code ? and it’s probably not an observer on an event no ?</p>
  
  <p>Maybe you could help me with it because i need to update this email with some important Information that I only got after I have a payment confirmation ..</p>
  
  <p>Anyway I wish you a nice sunday and maybe you will be able to help me,</p>
  
  <p>All the best for your different projects,</p>
