What does one check mark in WhatsApp mean in a sent message - in detail?

A single check mark in WhatsApp, when referring to a sent message, indicates that the message has been successfully delivered to the recipient's device. This means the message has left your phone and is now with the intended recipient, residing on their device. However, it does not confirm whether the message has been read or seen by the recipient. The single check mark only verifies the delivery of the message, ensuring that it has reached its destination. For further confirmation of the message being viewed, you would need to look for additional indicators such as two check marks or a notification stating that the message has been read.
