What does a bounce-back email indicate in mail delivery?

• A. A bounce-back indicates a failed delivery and includes an error code or reason (e.g., not found, blocked, mailbox full).
• B. A bounce-back means the mail is delayed but will arrive eventually.
• C. A bounce-back indicates the recipient’s mailbox is temporarily full.
• D. A bounce-back is a notification that the message was delivered successfully.

Answer: (A)

A bounce-back message is a notification from a mail server that the message could not be delivered. It’s essentially a delivery failure report that includes a status code and a reason for the failure, such as the address not existing, being blocked, or the mailbox being full. This helps you understand whether the problem is permanent (hard bounce) or temporary (soft bounce) and guides what to do next, such as correcting the address or retrying later. It is not evidence that the email was delivered successfully, and it typically points to why delivery failed rather than just noting a delay.
