How to keep my Sign-on email private and use a different one for Registration Enquiries?

[AnnieKate]

I use my private email for my account and would like to keep that as my Zoom sign-on. I don't want this private email address identified on the participant registration confirmation email. I want to use a Gmail account for attendees interactions. I had designed a meeting template ages ago, but cannot see how to change the email contact under the calendar options. it says "Please submit any questions to .....".   Any ideas on how to do this? Can it be done? Thanks in advance.
