I think that's completely appropriate. Any unwanted email is spam.

I hate to admit this, but we send a lot of email like this at work, and I always get tickets like "all of our email is being marked as spam, can you fix DNS?" Usually it is a DNS issue (people add email senders without setting up Spam Permitted From and DKIM), but nobody will address the elephant in the room that maybe users don't want to read our marketing newsletters. They likely get 100 of the same things from 100 other vendors, and at some point, enough is enough.

(Dunno if this is a public Gmail feature or one that I'm allowlisted into from working at Google in the past, but I have a "tabbed inbox" and everything like this goes in "Promotions". I look in there from time to time and see thousands of messages a day of this type. Everyone sends these and Gmail knows that nobody wants to read them. It's unfortunate, but true.)

Ha! At a previous company the marketing people swore that our mail setup was miss configured because very often people from the mkting team would get their gmail work account blocked for spam.

They were linking their accounts to use some spammy marketing software to mass send "campaigns ".

Marketing should be forbidden.

It's apparently a public feature, since I remember being annoyed by the tabs and disabling them in Gmail preferences.
