Does that mean that if you even receive an email from a list, they get notified that you opened and read it, even if you didn't? If so, that seems bad to me.

Bad for whom? If spammers actually wanted to use that as an indication of a live account, they'd need to just give up and ignore all gmail.com addresses, which would be win for ordinary users.

No. From the link:

> senders may be able to know whether you've opened an email that has an image attached to a unique link

My limited understanding is that the load happens on first open, from Google's servers.

Yeah, without the ability to cookie them, which I guess is the gain from that.
