If it’s a single email - then even if it doesn’t get caught in a Spam filter that’s still a short period of time to notice and respond when the stakes are so high.
If that email goes to junk, or you’re unwell and not checking emails as frequently (given - I assume - that many of Hetzner’s customers are individuals) or any other number of reasonable situations, you’ve effectively had no warning before service termination and deletion of data.
I don’t mind cloud providers acting on suspicious usage patterns or abuse reports but there has to be some kind of due process or it just ends up unnecessarily destroying goodwill in a brand/provider.
