What Are Stores Even Thinking with All These Emails?

The number of emails I get from Amazon is baffling. I never open them but I swear it seems like I get loads advertising kindle books to me, most of which aren't anything I'd read (they are books that are currently selling well, but aren't genres I'm interested in). Not to suggest Amazon is alone, lots of places send me 10s of emails a week.

Reflecting on it I think the main issue is that it works at least sometimes and sending me an email is basically free, so it only has to work on a tiny fraction of recipients to be worthwhile. This is why it is like physical junk mail but in much greater volume.

This is another case where our ability to do things at a large scale kind of make life worse. I swear I see more things like this where the affordability of being slightly shitty at massive scale makes life worse and I have no idea how we stop it without throwing the baby out with the bathwater and it makes me miserable.
