Both series are a case-by-case episodic manner, with some cases taking up more than one episode. Also, both are equally supernatural and while Neuro is more comedic and light hearted than Jigoku Shoujo, they both have a dark air to them.

Both of them have to do with the supernatural. While Fumika is going around delivering post-death letters, Ai is exacting revenge on other's behalfs and dragging them to Hell. Also both are psychological series as well.

They are both made by the same director, Makoto Shinkai. And I must say, they have incredibly similar themes. Not in subject matter but they both concern themselves with matters of the heart and the distance between humans. One is a force separation while the other is a gradual drifting apart. If you like anime that makes you think, watch these two.
