There's a lot of granularity in your notifications preferences found in the Alexa settings for the account your devices are associated with.

The shopping (and subsequently shipping) notification preferences are separate from "Following" and "News" notification preferences.

My "Following" preference is devoid of any sports, music, celebrities, movies, or financial interests. I'm following nothing. Same for my News notification settings. Anything I ever had in those two sections has been unfollowed/removed. It is extremely rare for me to receive any notifications on my Echo devices other than shipping/delivery notifications.

Turning off "Deal" and "Reorder" Recommendations in the Amazon Shopping notifications subsection drastically reduced annoying notifications for me.

From "Home" in my Alexa app, I go to the "More" tab on the bottom of the screen. Then I click on "Setting" (with the gear icon). From Settings I select "Notifications". And that's where all the individual notifications preferences can be found.
