>"Subscribing in the first place" almost always consists of forgetting to uncheck the "default opt-in"
Citation needed. Mail Chimp strongly recommends double-opt in, I think it's the default. I very much doubt its "almost always" single opt-in.
Personally, I consider any promotional mail that was not double-opted-in (that is I had to take some affirmative action to receive a confirmation link, and then I confirmed it) to be spam. I also consider any promotional materials stapled to transactional mail to be spam. I know I am not unique in this opinion.
