As another person mentioned, if you have gmail and visit here, google knows about every purchase you have made, the price you paid, etc: https://myaccount.google.com/purchases

They're not reading your emails, right? How else would they know this much information?

That's not what I said. I'd ask that you reread my comment. Your emails aren't used for advertising purposes. There are a host of features that require varying levels of email analysis (from spam detection to putting flight times on your calendar to reminders that you'll be receiving a package).

None of those things require targeting advertisements based on email content. And that's what isn't happening.

Perhaps not in the email interface itself, but you would be hard pressed to convince anyone that it's not shoved in a machine learning model somewhere.

I mean it's literally explicity in the privacy policy. They always kept email based targeting separate from broader data and stopped using it at all for ad targetting a year or two ago, seemingly because corporate (gsuite) users were concerned that the data might be used anyway or something, I'm not really sure.

I don't think you can get more explicit than "Consumer Gmail content will not be used or scanned for any ads personalization after this change."
