KDP Certified Expert

So I published my second book a few days ago, and this morning I received an email, unsolicited, from someone claiming to be a certified KDP expert, offering their services to help promote my book.

Now, generally I ignore all such emails, as they tend to be scams. There were no prices mentioned, and the website linked was very... unprofessional looking.

I don't know if I should name them, as I don't want to break any rules. Just wondering if anyone else has gotten emails like this. They did express how they liked my story, even going into a little detail, so they may well have actually read it, or at least skimmed it.

Anyone have advice?
