You probably clicked on something to activate them as I’m not seeing any e-mail from Sonos.
No clue where the “send marketing e-mail” is in the new app.
You might check your Sonos.com and forum profiles too.
It’s happening to me too - I didn’t do anything new. I haven’t even visited the site in months. Suddenly today 38 emails. Maybe trust the user before saying it’s their mistake.
@Stanley_4 it was actually a bug - Sonos moderator confirmed they have reported it to the platform: https://en.community.sonos.com/controllers%2Dand%2Dmusic%2Dservices%2D228995/new%2Dsonos%2Dapp%2Dfeedback%2D6892413/index90.html?postid=16796283#post16796283
