Your best defense if you receive a hit man e-mail? Forward it to the FBI's Internet Crime Complaint Center, then hit the delete button.
Responding in any way can just alert the spammers that you're vulnerable to scare tactics, leading them to flood your in-box with more spam and scam attempts.
And of course, never provide your bank account or any personal information, which opens the door to identity theft.
