How do mail services know when an email has been opened?

How do the services know when certain events happen?

I assume that "delivered" means the email server received a positive response from the destination server, or at least no error.

I assume "clicked" means the user clicked on a rewritten link in an email.

But how does the service know if someone has opened an email? Maybe a 1x1 image sprite or something? What if the user has set all email to text-only?
