Dodgy email

Apple will always address you by your name or the name they have on file for you, not Dear Customer, Dear Client or by using your e-mail address.  The e-mail will be from @apple.com or @iTunes.com. E-mail addresses can be spoofed. You can go to Mail/View/Message/Show all Headers to see more. Apple e-mails will never contain an attachment. Apple will never request personal information by email such as Social Security numbers, your Mother’s maiden name or full credit card numbers .

The only exception to the above I have noticed is if you order something from the Apple Store (apple.com), your receipt will be addressed to Dear Apple Customer. That is a receipt for a purchase you initiated.

Not in any way

if Apple legitimately suspended your account you would be notified when you tried to sign into it. No email would be sent by anyone from Apple.

If you received an email or phone call or text message claiming to be from Apple Computer with charges or claims you do not recognize or with requests to provide or change personal information DO NOT click on any links or respond to it.

Avoid phishing emails, fake ‘virus‘ alerts, phony support calls, and other scams
