> What data is a tracking pixel taking from you?

Let me just list a few of the things that I consider private:

* The fact that I viewed the email in any way

* The fact that the email was opened on more than one date

* What IP address is assigned to me by my service provider

* What user-agent is used by me (and what version)

* Whether or not I share my IP with other email addresses

* Bandwidth information about my network

* Latency information about my network

> None of that is your private information.

You are dead wrong on this point.
