There needs to be a way to create an active list based on when the last time an email subscriber opened ANY email and not have to manually select every single email you want included.
The "date last marketing email opened" does not include transactional messages, which should also be included in the "any" qualifier.
This is basic functionality and the graymail blanket doesn't allow for email marketers to create and compare lists and the number of subscribers in each. For example, I can't create active lists to see and compare who lands in the "not opened in 90 days" vs "not opened in 120 days."
