Problem with my domain

Problem with my domain

Hello. I'm having an issue when I try to register a new Zoho Email Account with my own domain.

The domain es: newhouseperu.com and I manage this domain (it's mine).

Nevertheless, when I try to register, I see an error that says: "* This domain is already associated with this account "i*****1@g*****".

But I have never signed up with Zoho, and I don't recognize that email adress.

As I said, I own this domain, so I can make changes of MX, verify by HTML, or another ways to prove that the domain is mine.

Please, help me.

Regards.
