Is there any way to see the creator of a nextDNS profile

I made a nextDNS account using a temporary email on 10minutemail. I made a profile and configured a device with that profile using that account. I then was signed out of the nextDNS account before I was done with it.

I need to get back in to that account. I remember the password but not the email. The private DNS link is 8a9abf.dns.nextdns.io

Is there any way to see the email of the account that created that profile?
