ProtonMail might be up your street. It fulfils points 1-4. See: https://en.wikipedia.org/wiki/Comparison_of_webmail_providers https://en.wikipedia.org/wiki/Comparison_of_webmail_provider...

So many of them require mobile phone activation and expire early, which is super unhelpful if you want a throw-away account.
