Having run a mailing list I can pretty much tell you that despite your best efforts to put the right headers in so Google can do their own unsub links, unsub at top and bottom, etc, that despite all this and being fully CAN-SPAM complaint that people will still write emails to your ISP claiming that your sending SPAM.
I'm not sure why but usually it's academics who send these. Maybe people sign them up for mailing lists b/c they are jerks or something. They all seem to be sure that they've never ever signed up for a mailing list.
ISP sends me email about the compliance issue, I put the email address into a form that blocks it from ever being associated with any of the lists on that server, and it spits back an email detailing when they signed up, confirmed, etc, that they've been blacklisted, and then attaches a jpeg image of the headers / footers with unsub links circled in red so the ISP can close the case.
You would be surprised. I've run several mailing lists for both technical and non-technical people.
Always, without fail, you will get someone that signs up, confirms and then mashes the spam button two emails later while sending you irate "HOW DID YOU GET MY EMAIL ADDRESS UNSUBSCRIBE ME OHGODWHATHAVEYOUDONE?!" emails.
Well yes, forgetting that you signed up is still possible if there's a confirm step. Being signed up (maliciously or accidentally) by someone else, however, is the situation I was referring to and confirm steps exist specifically to prevent that.
