Email Opt Out Reason and What Email made them unsubscribe export option

I also need this feature. Actually, I’m sure that I saw it for a couple of unsubscribes last year, but now I feel like I’m losing my mind.
I’m a free user and pretty much only use Hubspot for emails: I recently had 2% unsubscribe and am in danger of being permanently suspended. How am I supposed to know what’s going wrong without knowing why people are unsubscribing?? I’m scared to send any more!

Please get this back.
