Through extensive work unsubscribing to useless emails coupled with regular spam filters in an attempt at inbox zero, I've noticed the only spam that makes it through are Terms of Service update emails that are unsubscribable. Whether these emails be from Google, Twitter, Reddit, or any other company they exist solely as legal means of protection for the companies themselves, as end-users rarely if ever end up reading the large corpus of text that the Terms of Service itself entails.
Solutioning this through, TOS updates should be unsubscribable.
I also find the cookie filtering has gone slightly too far and I have to recommit to consent to trackers on almost everything which is a pain. stackoverload, every single time.
I really don't mind a cookie which confirms I saw the T&C and a more gentle reminder they exist, or have updated would be fine.
In-page over-draw of a consent popup is stupid. This should be standardised to a hotkey YES or NO function my browser does in a normalised manner.
My government login (Tax, Medical benefits) mails me to say it has CRITICAL UPDATES PENDING IN MY GOVERNMENT LOGIN MAILBOX. They are "we have updated the terms and conditions" which typically, I had to click through anyway, to read the mail. Every. Single. Time.
