Choose certified mail when you need proof of delivery and time is of the essence. Registered mail is the Postal Service's most secure form of mail delivery, involving an unbroken chain of custody. Registered mail is protected in sealed containers, safes and cages, and held under lock and key.
Certified email is a kind of email whose sending is certified by a neutral third-party, analogous to certified mail. A certified email aims to guarantee the same legal validity as a certified mail. For each certified email, the government will guarantee the legal validity with a delivery receipt that will be given to the sender.
