Cloudflare isn't the only one with this sort of problem. I continue to get email from FedEx every month instructing me to update my credit card information. The information they have on file is from a card that expired over 10 years ago, and I closed my account with them 12 years ago. I called them last month to ask them why they continue to send me these emails, and asked them to stop. Their response was that they cannot stop the emails. Even when I pointed out that my having no business relationship with them, and them not offering a way to opt-out is a violation of the "Can Spam" act, they shrugged.
