Zoom post-event emails data

[ReneeT]

We send post-events emails directly from zoom. 
I would like to have some data on the engagement with our customers, like how many people opened the email/clicked/etc. 

I can't find anywhere to pull those, was anyone able to do that?

Thanks, I was hoping to get an in-app solution. I do have access to other tools
