That's not really relevant here. The complaint is that you start getting promotional emails right away, meaning that adding you to a mailing list is instant, but removing you somehow takes ten days. Normally you can't unsubscribe from transactional email, as they serve to provide you with information you're legally entitled to. There might be companies that are foolish enough to use the same system for both transactional and marketing email, but normally you'd never do that, because you exactly risk having things like order confirmation, recalls, invoices and so on, be tagged as spam, if it uses the same system as the marketing emails. Frequently you can use the same provider, allowing for tracking bounce rates, open indication and so on, but even if it's within the same interface or set of APIs, the two things are kept very separate on the backend. They'd at least use different email addresses, but frequently also different domains/sub-domains.
I've done both transactional and marketing emails, and I've never seen a system that could not remove a user at least within 24 hours. I can imagine one, but you're doing something very wrong at that point. Ten days is deliberate.

As the end user: not my problem, I don’t care, I don’t need the implementation details.
I only care about what I see.
Sounds like an engineering problem that can be solved, and, more importantly, not my fucking problem.
