For the last year or so I've noticed an increasing amount of my legitimate professional interactions going into my "Promotions" tab in Gmail. The effect of which has been, after discovering a few mishaps of this sort, to now regularly and meticulously go through a massive pile of "Promotions" just to make sure I haven't missed something legitimately urgent or important. Prior to Google's classification errors producing this particular anxiety I used to basically treat the "Promotions" tab as spam to never look at. Now I'm going through all of it with prejudice which means I'm waaaaaaay more aware of marketing drivel than I used to be. As such, I'm pretty sure this "error" is intentional on Google's part to produce exactly this outcome of drawing eyeballs to inbox advertising.
