Which service provides a mailing receipt and proof of delivery, sometimes with a signature?

• A. Certified Mail
• B. Priority Mail
• C. First-Class Mail
• D. Marketing Mail

Answer: (A)

When you need formal evidence that you mailed something and that it arrived at the right address, you look for a service that provides both a mailing receipt and proof of delivery, with the option to capture a signature. This is what Certified Mail offers. It gives you a mailing receipt at the time you send the item and assigns a tracking number so you can verify that delivery occurred. If you want the recipient’s signature, you can add Signature Confirmation, which records the signer’s name at delivery, and you can also add a Return Receipt for a record of the delivery details. Other services, like Priority Mail, First-Class Mail, or Marketing Mail, are not designed to include these receipts and proof of delivery as standard features; they may offer optional add-ons, but the core service does not inherently provide the same guaranteed proof of delivery.
