Howdy Libbidydooda,
There are a couple of possibilities that may apply to the email you have received regarding your Apple ID. The first is that the email may be a legitimate warning that your Apple ID has been compromised. For this reason I would suggest that you change the password to your Apple ID as soon as possible. Use the instructions on this page -

In order to increase security for your Apple ID you may want to set up and use two-step verification. See this article for information about it -

The second possibilty is that the email is an attempt at "phishing" in order to get you to reveal personal information. Typically this is done with an email that looks like it comes from an official source but has links to web pages that, while they may look like they are real, may actually be gathering your information for use by others. This article has more information about phishing -

For this reason it is important that you do not follow any links in the email, as they may compromise your security.
Thanks for using Apple Support Communities.
Best,
