Used stamps exchanges.

I received an envelope from Remo (Switzerland): 11 mint and 62 used stamps.
No ID.
Not sure to which of clubs (used or mint) this is related.
Please help.

But you don't have a letter from this member through this club. Also you don't have a letter from Switzerland on mint club either.
