is this fake ??

Its very very fake.

Someone, has gotten a hold of your email and is trying to scam you unfortunately.

Apple will almost always address you by the name you have as part of your Apple ID, and never as "Dear Client".

Apple will never ever include an attachment for any purpose whatsoever.

Apple will have better grammar than that.

You can report it to Apple at: reportphishing@apple.com.

It is phishing. In a message Apple will always address you by your real name, never by your email address or Dear Customer. Also the sent-from address should be @apple.com or @itunes.com Additionally Apple does not send attachments.
