I had a problem where we did exactly that, "please read the document at this link because <list of reasons>". Check the logs, person had not even clicked on it.

I had a problem where we did exactly that, "please read the document at this link because <list of reasons>". Check the logs, person had not even clicked on it. Asked them about why they had not read the document mentioned in email, and proceeded to show their phone's email app, said "Yes, I read it, see here, the message is marked read in my email."
