As already said, it's a scam.
They probably send zillions of these out, in the hope that some genuine Apple customers will click on the links and input their passwords and other sensitive details.
If you ever receive any emails claiming to be from a reputable source, asking you to click on a link and input your details ..... it's more than likely a scam.
If in doubt, go to the website in question, by manually inputting the address yourself - do not trust a link that you click on, unless you know for certain the source of the email.
