If a business sends mail that I've not previously indicated I'm ok with them sending (newsletters out of the blue, unasked for "summary of stuff you've missed" emails, etc), then it's spam and will be treated as such.
I have to actively fight to keep my inbox empty, and free of crap. And while I'm ranting, notifications I actually want on my phone are co-opted by advertisements, which Apple and Google should actively prevent, but they won't because they use push notifications to commingle advertising to you with important, sometimes time-sensitive notifications.
Everyone thinks they have something worth sharing. Over three nines of the time, people don't. I will happily be apart of the 0.1% who sends your crap straight to the spam filter for Gmail to train.
It's spam. It's almost all spam. Even the transactional stuff for logging in, I don't want. Just use an email, password, and TOTP. Stop sending me emails.
Stop it.
