DoorDash is both better & worse (mostly worse with the slimmest silver lining) than you’ve portrayed. Inside the app settings you can turn off all the marketing notifications. They’ll even mostly respect that setting with the following caveats:

1) they will give you a recurring pop up banner when you open the app to turn on all notifications, making it sound like it’s just for delivery notifications, even if you already have those turned on. You have to ignore it.

2) at least once recently, they just toggled them all on, on my behalf, anyway. I found out after receiving a random marketing notification. Then I turned them back off & it hasn’t happened since.

3) there have been occasions where even with granular controls, I don’t receive the delivery notifications if I have the marketing ones turned off. Hasn’t happened in a while, but now I always keep that in mind that it’s a possibility.
