@shortridge I've largely given up tbh. Now I just don't pay any attention, and "report spam" on every email I see that I don't want. And I encourage everyone to report-spam on any undesired mass email - it's one of the few ways we have to push back on companies ignoring that box, so push back hard and often.

As a bonus, my spam filters gradually get better and better at blocking *all* kinds of promo newsletter nonsense automatically.
