I've seen some businesses send a pre-billing email telling customers that they'll be charged on a certain date, so that customers have time to cancel if they want.
Cloudflare does that for domain renewals, sending out emails 30 and 60 days before.
Of course, there are also some businesses that hope that customers forget that they're subscribed, so that there's breakage.
Anyway- turns out that on the rare occasion someone’s had an issue, this gives them a really easy mechanism to write to me and tell me about it. They let off their steam in the email and then we make things good together. (Yet another reason why I always oppose noreply email addresses)
I still don’t know what or where the setting is, mind.
It does have the description of what you're buying ("Dead Man's Switch subscription") but I don't know if that gets to the bank statement.
That's just standard. Every domain registrar/vendor does this.
