If your email click report looks unusually high it may be due to bot activity. All of the below symptoms are telltale signs that a spam filter is clicking on your links:
unusually high click rate
clicks by the same recipient (especially from the the same domain) to every single link in your email
clicks from emails ending in certain domains are much higher than from other domains
clicks that seem to have come from a bot (lots of clicks recorded within a very short period of time)
contacts seem to have accessed links directly instead of clicking on a button or link in your email. For example the click report shows links directly as https://abcdomain.com vs "Read more" even though you didn't have https://abcdomain.com as a link in your email.
Some spam filters click links in emails as they analyze links for potential malicious content.
