What is essential for proper mail handling before delivery?

Verifying delivery addresses and checking for damages is crucial for proper mail handling before delivery because accurate delivery is fundamental to the postal service's efficiency and reliability. Ensuring that the address on each piece of mail is correct minimizes the chances of misdelivery, which can lead to significant delays, customer dissatisfaction, and additional handling costs.

Additionally, checking for damages helps to maintain the integrity of the mail. Any mail that is damaged might not only affect its contents but also might pose a risk during transit or delivery. By addressing these issues beforehand, the postal service can ensure that the mail reaches its intended recipient in good condition and without unnecessary complications.

Other factors like the amount of stamps, sorting based only on size, or focusing solely on speed of delivery may contribute to the process but do not capture the holistic view of ensuring reliable and safe mail delivery as verifying addresses and checking for damages do.
