This is true, but the intent probably isn't for the individual to sue, it's for them to report it to the relevant rule making executive agency who also has standing to sue (or just has standing to fine them directly depending on the agency and the rule, I don't know who governs this or if they have that power or not).
The relevant agency would be the FTC, but is the FTC even interested in pursuing these cases? I've seen a few cases where they sued scammy businesses (https://www.ftc.gov/news-events/news/press-releases/2019/12/...), but there are lots of legitimate businesses that are nonetheless breaking the law. For example Xfinity sent me an ad for a voice-activated remote, categorized it as a "service-related email" and had no unsubscribe link. Instantly marked as spam.
What I want to know is: has there ever been even a single case of the FTC going after one of these real companies?
Experian sends me marketing emails classified as service-related as well, seems like once a week at least. Thankfully, Gmail has learned that I always mark them as spam and classifies them accordingly, though I wonder if it'll do the same if a non-marketing email ever comes through.
