How to unsubscribe from spam from nic.ru?

Question

Law in IT

Zadolbala mail from nic.ru:
New domains: .ZONE, .COOL - accept applications.
Change of tariffs for RU-CENTER services.
Priority registration of PW domains.
Thousands of them.
There is no way to unsubscribe inside the email.
On the site, in my personal account, I have already rummaged through everything.
Of course, I will never be their customer again, but will that save me?
I wrote to them in support. No answer.
Does anyone have any positive experience or advice?

Answer 1

Got a response from tech support, all of a sudden.
This is not an advertisement, these are important notices.
Can't unsubscribe.
