TOPIC: Which sentence is correct?

Would you mind telling me if the following sentence are right or if they need a revision?
1) Today I read a material related to your case.
2) I got some informations that are related to you.

I am afraid that neither sentence is correct.
"Material is uncountable and so can't be with "a". You could say "some material" or "a document".
There is a similar mistake in the second one. "Information" is uncountable. The sentence should read "I got some information that is related to you."
