Dear alien species or some sort of human

I am writing to you today because I am curious if you will respond or will track us and destroy our planet. But we will send it through a black hole and hopefully it goes to a planet which leads to you, so, if you receive this letter please do not track us and destroy us. Plus you will get a card and envelope to send something back. Wherever you are that it could be further than the farthest star; or in the fourth quadrant of the fifty-sixth star.
