The domain is assigned clientHold status, why?

Question

Computer networks

The domain was used only for mail from Yandex, there was no site there, but the domain was blocked. Tell me why this happens?

Answer 1

It turned out that I did not confirm the email address and the domain was blocked.

Answer 2

This question should be asked to the provider from whom you purchased the domain and from which you periodically renew it. Technical support will immediately answer you the exact reason. There will only be speculation here.
