Did it mention QuickBooks?
You should exercise a very high degree of care with respect to this email considering Support is unaware of the name of the product and you can't find any information online.
It could very well be legitimate, or it could very well be a scam.
You might want to see if there is an embedded link (or visible one) in the email but do not open it or navigate to the site. Just note the name and other information contained in the link (if any).
