Additionally, Adobe software tells the authors of

Kind regards Philippe
I thought that was actually in CS and put in by a 3rd party tracking company?
Yep. Adobe simply allows code in the document, and code can do many
things, good and bad. It's up to the document writer to use those
capacities.
It is not much different from viewing an html document with images
downloaded from the web: anytime you view the document downloading the
image, the server knows you are reading it. If you apply it to email, it
can act as the "recipient has displayed your email in his computer"
receipt. If you use a 1 byte image with name different for each targeted
recipient, the sender can learn which of those email addresses he sent to
are active and "worthy" of sending more spam.
