In order to get a report defining all of your guests by subscription status, you simply run the normal Guest data export at Reports>Data Export>Guest Data with particular emphasis on two fields (columns) in the CSV that is delivered to your logged in admin user email:
"Marketing email subscription status"
"Marketing PN subscription status"
When configuring the report, make sure these two fields are moved to the right side of "selected fields"
