Tracking openings of manually sent emails

Hi,
I want to track email openings when emails are sent manually (from the “Send Email” button on top of the single contact page). I tried and I see that the system sees the open email inside the contact events. However, in the reports page, I see nothing.

Is there a way to see those openings in the reports? Thank you

Sorry for bumping this, but does anyone have an idea? Thank you :slight_smile:
