Recover a customer email hosting account when there is no support number to call?

Hi everyone.

I have a customer that his email is being hosted in Cloudfare and they don’t have the account info. Someone created it for them. How can I recover a customer email hosting account when there is no support number to call?

Cloudflare doesn’t host email, they provide email routing (forwarding) and Area 1 (filtering/security) but don’t host mailboxes.

Can you clarify what you mean?
