Account delete e-mail from Apple

I got an e-mail from Apple saying there was content in my cloud that was not allowed. I was asked to submit an appeal or my account would be locked for 24 hours or deleted in 72 hours , the e-mail address doesn’t look right . I did not think Apple had access to my family photo’s and documents and notes I keep on the iCloud. Could this be some sort of scam. I have been an Apple user for years and never got anything like this before . If my Cloud is full I just send to my e-mail and load the photo’s etc down to my laptop and put on an external drive . Anyone get this e-mail?
