Hi,From your request, only opens can be tracked. If an email is forwarded, opens will be counted for the initial recipient, but Campaign will have no way to know if there has been a forward.There is no way of knowing if an email has been deleted or if it landed in the spam folder. I think it cannot be customised either.I'd suggest to have a look at these 2 documents:Deliverability best practices: information about inbox rendering, spam checks, and much more.Information you can see from the Track...
