A bounce message is typically triggered when an email cannot be delivered to an intended recipient. This often occurs due to invalid or non-existent email addresses. When a message is sent and the server cannot find the recipient's email, it generates a bounce message indicating that the delivery failed. Bounces can happen for various reasons, including a typo in the email, the inbox being full, or the address no longer being active.

In contrast, successful email deliveries do not generate any bounce messages because the email reaches the intended recipient without issues. Clicking on links within the email indicates user engagement, which also doesn’t trigger a bounce. Lastly, unsubscribing from a mailing list is a deliberate action initiated by the recipient; while it may prevent future emails from being sent to that address, it does not result in a bounce message at the time of the unsubscribing action.
