It is less likely that someone would send a falsified bank document through the mail, as mail fraud is a federal crime with harsher sentences than most online versions of spam/phishing. Also records are kept for mail regarding where it was received by the post office (which likely has security cameras), when, who is on the return address and the recipient. There is physical evidence of who has touched a piece of mail such as fingerprints, hair, DNA etc. This is part of why you don't get 50 letters from nigerian princes each day
