They do have an unsubscribe from all button. It's in the delete my account because i get too many emails user flow. Ask me how i know. Nextdoor is a master class in dark patterns.
Most email sending services have upper caps on acceptable complaint rates, and if done by a sufficient number of users, would result in a suspension of their sending capabilities, and an IP address block on whatever email service you’re using.
I like the idea but I doubt it. Who do you think is enforcing this? Their transactional email provider don’t want to lose the business, Gmail/MS/Fastmail aren’t going to spamhole a big legit business…
I used to work for a email sending provider a few years ago. For smaller senders close to breaching the limit, warning emails would be sent out reminding them about email sending practices; for larger senders these would take the form of meetings set up between the customer and their account manager about the issue.
The only kind of spam anyone really seems to care about is truly unsolicited email. A publicly listed company with an aggressive stance towards emailing their existing users, nobody is going to get excited about.
The problem, if anything is that people kinda don’t know about what to do with these emails, and if more people marked these emails as spam, senders such as Nextdoor would sit up and take notice.
