How to fix this problem? Different email for uphold and publisher

Email A: is a verified uphold account and not a publisher account.
Email B: is not a verified uphold account but its my verified publisher account.

I registered my Email A to publisher account while ago.

Question 1: Can I use my verified uphold account to both of my publisher account?
I can’t disconnect my Email A verified uphold account to Email B publisher account because I have a remaining 17 BAT there.

Question 2: How can I delete my Email B unverified uphold account?

Question 3: Is it okay to use different email for publisher and uphold account? If yes then how can I delete my unverified uphold account?

Thank you! stay safe people!
