record of unsubsribes?

Hello,
I just had someone request to be removed from our email list, but when I checked, I did not see their name or email in any of our email lists. Is it possible that they unsubscribed themself? Is there a list of people that have blocked our email to check? I know that he used to be on our list, but he was not there anymore so if there is a record of him being removed that would help to check.

Thanks.

Did you check the former members or guest list. Without the name and club number we can't tell you anything.
