 They're using a web bug.

 There was a lengthy discussion of didtheyreadit on spam-l, but you need to
 be a subscriber to get access to the archive.

I think their product (which does not deserve to be called a service) is 
sneaky and vicious.  It's nobody else's business whether, much less 
WHEN, I read a message.
 
 Fully agreed. And while we're at it, I'm also filtering out DSN and
 return-receipt headers here. The initial reason for that, though, was
 that we received email from luser sites where the address in the DSN/
 return-receipt headers wasn't masqueraded, and therefore not deliverable.
