If I might throw in my two cents - I'm currently building something very similar, however for mine we're tracking not on "read" emails but rather bounced or rejected messages using the reply to email address to catch anything coming back using CF.
Every customer gives us an email account that we can CFMAIL from and CFPOP to check. Once a campaign has been sent the system begins looking for replies in that account and logs as needed. For tracking messages read I do a couple of things: 1. I create a "static" version of the HTML message and the text body includes a link to it with the text "Can't see this message..." 2. In the case of HTTP links to the customer's site, I have built a "turnstile" that grabs the appropriate information, logs it and forwards the visitor on to the appropriate link. 3. I provide both a SEND TO FRIEND and UNSUBSCRIBE link that are also logged. My biggest problem so far is making the HTML appear correctly in all the different clients. THAT is a bear in my opinion.
