There is no such thing as free money.
You wouldn't believe it if a stranger walked up to you and said they'd just deposited money into your account, would you? So, why on earth would you fall for the email below?
Instead of opening that attachment you should check with your bank directly to see if a wire transfer has been credited to your account. Never, ever, ever open an attachment from a sender you don't know and trust. Ever.
I've copied the email I received yesterday morning below so you can see it. If you get an email like this just delete it. There is no such thing as free money.
Not sure if what you got is spam? Call me at 203.987.4566 or email me your question email@example.com
