I don’t share my Gmail address to anyone an email address to anyone I don’t want sharing emails or Gmail

So don't give anybody your email address. I have had mine on my Apple account as my Apple ID for over 20 years now and I don't get any scam emails.

If you don't like scammers then don't fall for any tricks by them.

O.k, and what exactly is the issue then?

Is something asking you to share your gmail address?

If you explain what is happening exactly, someone may be able to help resolve it.
