That's a great question! We have seen cases where multiple opens are tracked in our system due to forwarding emails or even the security programs of your contacts. The security programs of addresses with strong filter settings will trigger engagement tracking by opening emails before placing it into the contact's inbox. This tends to be opens tracked as soon as your email is sent. At this time there is not a way to remove these opens from your overall reporting. Because of this we would recommend viewing the unique opens for your campaigns instead.
