In more recent media, it may take the form of an e-mail or text message. A specific subtrope is Never Sent Any Letters, when someone realizes that their communications have been forged, generally over a long period of time.
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.
Alternatively, this can be Played for Laughs with a message faked so ineptly that only a complete idiot would fall for it (though it may succeed if the recipient is indeed a complete idiot).
This can overlap with Impeded Communication.

Practical doesn't fall for it: along with the bad penmanship, he recognizes the Wolf's breath when he blows it under the door.
