Why is there only one check mark when sending a message in WhatsApp - in detail?

When you send a message on WhatsApp, you might notice that it initially shows just one check mark. This single check mark indicates that your message has been successfully sent from your device to WhatsApp's servers. However, it does not confirm whether the recipient has received or read the message yet.

The absence of additional check marks at this stage is designed to provide a clear and immediate indication that the message has left your device. It helps users understand that their message is on its way, reducing potential confusion or concern about delivery failures. Once the message reaches WhatsApp's servers, it will be queued for delivery to the recipient's device.

As the message travels from WhatsApp's servers to the recipient's device, additional check marks will appear based on the delivery status. If the recipient's device is online and able to receive messages, two check marks will eventually appear beside your sent message. This double-check mark signifies that your message has been delivered to the recipient's device, although it does not guarantee that the recipient has seen or read the message.

The use of a single check mark for initial sending is a crucial aspect of WhatsApp's messaging system. It ensures users are aware that their message is in transit, offering reassurance without overloading them with unnecessary information at this early stage. Once the message status changes to delivered or read, additional check marks will provide further updates on the message's journey and receipt.
