A web bug can be used to obtain an email recipient's IP address, as well as to collect the following identifying information, through tracking tokens:
The time when the web bug was viewed/visited.
The type of email reader or web browser or that made the request.
Previously set cookie value on the host server.
Email-sourced Web bugs simply report back to the sender that someone opened an email, therefore validating the existence of that email address.
