Which of the following is a key step in accepting mail for delivery?

Verifying postage is a crucial step in the mail acceptance process because it ensures that the sender has paid the correct postage for the item being mailed. This step prevents any potential issues with postage-due items that could arise during delivery. When postage is verified, it helps maintain the integrity of postal operations and ensures that mail is processed efficiently and compliantly according to postal regulations.

Weighing the package, summarizing delivery methods, and providing estimated delivery dates, while important in the overall mail handling process, do not directly ensure that the mail is ready for delivery in the same way that confirming proper postage does. Without proper postage, the mail cannot be accepted for delivery, which makes verifying postage the key step in this context.
