Cedric's Burning Epistle

You send a one-page letter to a creature(with which you are familiar) by placing it into an open flame. The creature recieves the letter in a puff of smoke, and it recognizes you as the sender if it knows you. The creature must be able to read the language that the letter is written in to understand it. The letter is magically incinerated immediately after being read by the creature, and the creature cannot reply to it.
You can send the letter across any distance and even to other planes of existence, but if the target is on a different plane than you, there is a 5 percent chance that the letter doesn’t arrive.
