In today's digital age, physical mail has been mostly replaced by email. However, there are still uses of physical mail today, such as sending official and legally binding documents. These cannot be sent electronically due to their sensitive nature and the fact that email can easily be buried in the recipient's inbox or diverted to the spam folder.
To increase security and ensure the mail is received, senders can use Certified Mail®. This is a service provided by the United States Postal Service (USPS) that provides the sender with proof of mailing and verification that their letter has been delivered.
