Cannot create email again after deleting my old account

Cannot create email again after deleting my old account

I created a user under my account dmvestudio.com in zoho mail.  So, I got lost in setting up a new email account, and I decided to cancel that account to create another account. B ut Zoho now tells me the email already exists.
the email ID I created was contato@dmvestudio.com.

How can this be corrected? (I'm sorry for my English)
