The ability to un-send messages within a short window after sending them is provided by the "Undo Send" feature. This feature allows users to quickly retract a message after it has been sent, giving them the opportunity to prevent a message from reaching the recipient's device. This functionality is particularly useful in situations where a message was sent by mistake, such as sending it to the wrong person or including unintended content. Once activated, this option typically offers a brief period during which the user can reverse the action before the message is delivered, thereby reducing the likelihood of miscommunication or embarrassment.

In contrast, other features such as marking a message as unread or editing a message do not have the same immediate effect of preventing a message from being sent to the recipient in the first place. Additionally, the concept of recalling a message is often associated with email services rather than messaging applications, and it usually requires more complex actions that may not guarantee the same immediacy or effectiveness as simply using "Undo Send."
