Hello @PTDA ,
If their network or email program uses some kind of security tool that "opens" emails and "clicks" their links to check for malware, it can result in that kind of data. In all honesty, the only suggestion I normally have is to setup your account for self-authentication, however you've already got this on your account. This can show the security algorithms that emails being sent through us by you are effectively coming directly from you, and avoid triggering the clicks/opens from bots, but it's unfortunately not a guarantee as some security programs are simply built to function like this.
Beyond that, there's not much else you can do from your end. Our devs are constantly trying to identify the various programs that utilize this functionality, so they can set our system to ignore the behavior and triggers from these particular programs. If, after setting your account up for self-auth, the click rates continue to be inflated or worsen, then it may be worth calling in. That way our general support or higher level technical team can see if there's any further info that can be gleamed from the content of the emails with you live on the phone, or to see if the domains of the contacts that are seeming to bot-click them show any other particular consistencies we can track.
