I need to be able to track PDF files that are sent out by email.
The issue we have is that a newsletter that our company distributes only to its clients has appeared in the press. Its not something that we would like to happen again, so we are trying to work out if there is a way of tracking PDF files once they are sent out by email? Can we then see if the file is forwarded on to anyone else?
Also, what are the legalities around doing something like this from Data Protection and Privacy standpoints?
Thanks in advance
