In United States v. Gerson Cohen, it was evident that the US mail was used to spread a fraudulent scheme.
“To prove mail fraud under section 1341 of the government must show: a scheme to defraud, committed with intent to defraud and use of the United States mails to further the fraudulent scheme. The government is not required to prove that the scheme to defraud was successful. It need only prove that a scheme existed in which use of the mails was reasonably foreseeable and that an actual mailing occurred in furtherance of the scheme.
