AI marketing is not different at all from performance marketing of other solutions. This is really just ordinary consent management and privacy problem. I have participated in large scale email marketing implementations too, and know how it looks from the inside. As a tech partner you may even have a good peer on the business side who cares about customers and compliance, but institutional resistance is still hard to overcome. Sometimes it is just as dumb as an old spreadsheet with contacts being uploaded again and again into your mass mail system, without any consent tracking and ignoring any opt-outs that came after the spreadsheet was created.
