In more recent media, it may take the form of an e-mail or text message.
These can be used in a Batman Gambit, as they are usually written with the expectation that the recipient will react in a certain way. Quite often they can be used to lure someone into a trap. Other times they may be used to arrange meetings between people by a third party. They may also be used by well-meaning people in a Feud Episode to end a fight between others by sending a letter of apology on their behalf. How successful this can be varies.

This is the final straw that sets the stage for one hell of a Roaring Rampage of Revenge.
