E-mail Bugs

A web bug is an object that is attached in a web page or email and it is invisible to the user. It allows checking that a user has viewed the page or email. The web bugs that are embedded in emails have greater privacy rather than web pages.

Web bugs are used in spamming as a way of determining which spam recipients before deleting it.

How to disable web bugs:

1. To avoid web bugs by turning off HTML display or display only text.

2. Turn off display of images while still using HTML because it may still allow other techniques to be used.

Uses:
