How Can I Keep My Email Confidential Dodgy Email...?

Dodgy email...? - how can i keep my email confidential

I received a message that it $ US850, 000 won, that all I had to do is to protect the confidentiality of the e-mail and give them some information about me - what I can see that my numbers do not require any bank or something similar - they just want general information. It is a gift from the Church of Ireland.
What I know is that someone knows where I can report this kind of material? I know its doubtful, and I wouldnt be to overcome anyone. I am in Australia and I do not know if I am on the report, there were here and there is another place.
