I had 2 of these just this week. Disney+ sent an ESPN ad with no way to unsubscribe, despite my having all marketing emails turned off. Their chat rep absurdly and laughably insisted it was not a marketing email, just a way to help people use their services.

Best Buy sent me a marketing ad with a $5 coupon (lol) attached and again no way to unsubscribe. All marketing emails were disabled with them too.

Both problems were easily solved by deleting my accounts.
