A word of warning should be added.

There are configuration in emacs, for which  such a tracking is
successful.

For example using gnus the setting

(setq gnus-blocked-images nil)



Explanation.

I was not aware of this sort of tracking software and found out that
google's chrome browser has dozen of extension for email tracking, some
of them commercial. I downloaded and tried all of them, (well the ones
which did not require a payment). I then sent message to my own account
(my university switched to a google account which I access via imap).

Indeed with the above setting one extension successfully discovered that
I read an email with gnus/emacs.
