Poor man’s copyright: Mailing something to yourself doesn’t work.

www.slate.com: You could have heard about the “poor man’s copyright” anywhere: from an older relative, from a friend, from a high school English teacher. They find out that you’ve been working on a novel and they want to help, so they tell you to mail it to yourself once it’s done. That way, even if you don’t do anything with the novel for years (or if those snooty literary agents and publishing houses are incapable of recognizing genius when they see it), you still have a copy bearing an official federal date—and no one can steal your spot on the New York Times best-seller list.
