Marketo's Program performance analytics report cannot bring in the email address column in the report (as this report was never meant to give you insight into the individuals, but rather provide an aggregated program performance view).
You could instead set up a people performance report for this as follows:
-> Create smart lists with Member of Program Status is <channel-status name> for all the available status values in program channels that you want to report on.
-> Use the smart lists as custom columns in the report (you could only add up to 10 custom columns per report so you'd have to create multiple reports, preferably one for each channel).
-> Group the people performance report by Email Address
-> Use the report's smart list filters if you want to filter the results.
You could also use the Program Membership Analysis report available in the Revenue Cost Explorer (RCE) or the bulk program member export API to get the program member details along with their program status values.
