This is weird. That email reads as very scammy/phishy to me... just a lot of awkwardly phrased sentences, and the logo at the top doesn't match the logo on the official bn.com site or the logo in other emails I've received from them.
That being said, they've definitely had issues over the last few days, so it does appear something is happening. They have this notice posted on their site:
We are continuing to experience a systems failure that is interrupting NOOK content. We are working urgently to get all NOOK services back to full operation. Unfortunately it has taken longer than anticipated, and we sincerely apologize for this inconvenience and frustration. Please be assured that there is no compromise of customer payment details which are encrypted and tokenized. We expect NOOK to be fully operational shortly and will post an update once systems are restored. Thank you for your patience.
And this blog post has some other updates:
Barnes and Noble is experiencing an outage on their Nook e-readers and the Nook apps for Android and iOS. The Nook libraries are not syncing or loading purchases, which means you cannot read ebooks, view your purchases or make new purchases. The entire system has crashed and it won't be fixed...

I received a notification a couple days ago that there were issues syncing Nook content, but I haven't received an email about a breach. Hmm.
