title: What is the best way to implement an unsubscribe link for your newsletter?
body: <p>I am thinking that I create a deactivation code put that in the unsubscribe link along with their user id.  Then when a recipient of my newsletter clicks the link, I can look up their user id and see if the deactivation code matches.</p>
  
  <p>Does this sound like the best way?</p>
  
  <p>What are some other ways?</p>
