I'm trying to track analyitcs of my engagement programs. Most of the emails in my engagements were used prior to being added to engagement programs, and when I run analytics on the email, it is showing analytics for all-time email stats (when it was used in the engagement program, and when it was used outside of the program). Because all emails were used as a different time, it's not possible to add date used constraints.
Anyone have recommendations as to how to track specific email stats within engagement programs?
