Which scenario could lead to a message being counted as a Bounce?

A message being counted as a Bounce typically occurs when the email cannot be delivered to the recipient's inbox. This situation often arises if the email addresses are incorrect or deactivated. When an email is sent to a non-existent address or to an address that has been closed or disabled, the mail server responds with a Bounce message indicating that the delivery has failed. This process helps maintain a clean and healthy email list, reflecting the importance of up-to-date and accurate recipient information.

In contrast, other scenarios do not lead to Bounces because they relate to actions taken after the email has been successfully delivered. For instance, opening an email multiple times or ignoring push notifications indicates user engagement with the content already delivered, which does not affect the email deliverability status. Similarly, a user actively engaging with the content confirms that the message was successfully received, again not indicating any Bounce situation.
