Best Answer: A certified letter is sent by a person or a business when they want to mail important information and be sure that it was received. It's not usually a good thing. Collection agencies send them, people involved in legal cases send them, etc... If you won a sweepstakes you would get them.
At the first delivery attempt, if there is no authorized recipient available to sign for the letter, USPS will leave a Notice (PS Form 3849) informing the recipient that a piece of Certified Mail is waiting to be received/signed for at their local Post Office.
