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.

Certified mail allows the sender to obtain proof the addressee has received the letter or parcel. Only first class and priority mail can qualify for certification. The United States Postal Service is required to obtain a signature of receipt from the addressee. The signature, time and date of the signing can all be used in a court of law as evidence if necessary. The postal service has made it very easy to check the status of certified mail online. Find your receipt.
