Email from rewards(at)reward.tremendous.com is not SPAM [pdf]

I got the FirstEnergy settlement email this morning and was very suspicious, but I'm finding multiple sources online claiming it's legitimate.

Is this an intentional design to make it so that people don't claim the money? It has to be this bad on purpose, right?
