> the only way to stop the marketing was to cancel my membership of the club altogether

I have experienced this same thing with at least one other big company in Norway.

I could opt out of either SMS or e-mail, but not both, or I would not be able to keep the membership.

Unfortunately, I never made a note of which one that was exactly so I can’t name them and shame them on the spot.

Despite half-hearted attempts at stopping marketing emails now and then by individually logging in and opting out, or clicking unsubscribe links embedded in the email, my email continues to be flooded with marketing both from domestic and foreign companies that I’ve done business with. There is so many companies that even going through a handful of them at a time and unsubscribing there is a seemingly endless amount of companies that remain to unsubscribe from.

It is great to see that someone fights back, and that it is resulting in fines.
