HelloTorsten,
I think the different of :

You = when you to refer to other person.
Your= When you to refer to the possession.

Thanks for your English class .

According to your question, you is asubjectivepronoun, .It is also an objective pronoun. You are an English,Iam not. I sent you an email last Friday.
YOU IN SENTENCE ONE COMES BEFORE THE VERB SO IT I9S CALLED SUBJECTIVE PRONOUN .YOU IN SENTENCE 2 COMES AFTER THE VERB SENT , SO IT IS CALLED OBJECTIVE PRONOUN . YOUR WITHOUT S IS A POSSESIVE ADJECTIVE. YOURS WITH S IS APOSSESIVE PRONOUN .
