Possible fraudulent Xbox email on apple iPad

Hello, I received an email from Xbox series and when I clicked on it to unsubscribe I got the screen that says my connection wasn’t private which could mean hackers were trying to get into my iPad. I closed the email and trashed it.

Two or three years ago I constantly got an Amazon page that would come up telling me I won something and I finally stopped using Safari because of it.

Back to my original question, if I get this Xbox email again how can I report it? Apparently Apple doesn’t have an email address. I don’t want to keep getting these Xbox emails even if I can just trash them.

thank you
