My favorite one is where the unsubscribe link is behind a Cloudflare country IP block. Subscribed in the US but can't unsubscribe after moving.

My favorite is when the unsubscribe gateway isnt https.

Worried that your isp knows you unsubscribed?

I don't think https prevents ISPs from knowing what domains you try to resolve - that would be where a VPN would come into play surely?

The domain would only be relevant if the domain was a specific opt-out domain. If it was just https://company.com/unsubscribe, DNS would only reveal company.com. The path (/unsubscribe) will be encrypted.

Correct. DoH is also useful for preventing ISP's from snooping on that too IIRC.
