Suspicious Email Open and Click Stats
We have seen rising open and click numbers on our emails over the past month or so, culminating in a send this morning that claims the following in the email performance report:
1115 delivered, 1063 opens, 1057 clicks
Even considering we may be doing a wonderful job with our email marketing, these numbers are completely unrealistic. After looking into several dozen leads that clicked on this email, their activity logs all look something like this:

They have a "Send Email" and "Email Delivered" line, then strangely NO "Open Email" line, followed by multiple "Click Email" lines that abruptly end about 30-40 minutes after delivery. All of the time stamps are different, but the pattern is consistent throughout all leads we checked.
I've never seen anything like this and it doesn't really align with normal bot activity I'm familiar with (seeing email delivered, opened, and clicked tags all at the same timestamp, for example). But I'm certain this isn't legitimate data.
Has anyone else seen something similar? Any thoughts on what might be causing this?
Thanks so much!
