title: Can I add google analytic to an email (both html / text version)?
body: <p>I am wondering whether i can add google analytic to an email.
  I want to check my click rate , open rate of my sent mail. I have done some research on this and I learnt that there is a  track code should be useful.</p>
  
  <p>So,
  Since now i am sending an html version email, is it possible to add the code into the mail?</p>
  
  <p>Also, 
  If i want to see the result of it , is it possible i do not need to login to the google page, but connect to their server and retrieve the result and show them on my php page?</p>
  
  <p>Thank you</p>
