I appreciate the thought, but I don’t see how that complies with either the spirit or the wording of the GDPR. One of the goals of the GDPR is for data controllers to obtain explicit consent that is rather granular in nature - aligned with the purposes for each data collection. In the case of me providing a form allowing people to subscribe to my blog, the ostensible (and stated) purpose of me collecting their email address is so I can send them emails notifying them when I post a new article. But, if I’m also using their email addresses to track their interaction with my emails, that’s a distinct and separate purpose to which they never consented.

Embedding implied consent to such tracking in a separate document (privacy policy) does not seem to be very transparent. What am I misunderstanding?
