Is The Email I Received Claiming To Be Coming From Apple Legitimate?. Here's The Explanation.
Did you make any changes like billing address or credit card details? The address for the Apple ID looks legit. This is the same website address: https://appleid.apple.com.
Also, if you go to the Sent information and click From, it should show you the email address of the sender and they should end with apple.com. Example @email.apple.com or @orders.apple.com.
If you suspect a phishing scam, you can always go to the Browser and type the email address.
