I got an email from 'Apple' I need to know if it's legit?

I have never received an email from that address, and others are split on whether that address is used by Apple or a scam. The point is that you cannot trust any email header even if it is one used by Apple. Do not click any links from an email, call a provided number, or reply with personal information.

How you proceed will depend on the content of the email. If it claims there is a problem with your account, contact Apple directly using their official contact information.
