Why is there only one check mark in a WhatsApp message - briefly?

The single check mark on a WhatsApp message indicates that it has been sent from your device but has not yet been delivered to the recipient's phone. This is an initial status update provided by WhatsApp to inform users of the message's progress.

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

The presence of a single check mark in a WhatsApp message indicates that the message has been successfully sent from your device but has not yet been delivered to the recipient's phone. This status is crucial for users as it provides immediate feedback on the initial stage of message transmission.

When you send a message on WhatsApp, it first travels through your internet connection to WhatsApp's servers. The single check mark appears once the message has left your device and reached these servers, confirming that the message is on its way but not yet received by the intended recipient. This initial step ensures that your message is queued for delivery, even if the recipient is currently offline or without an active internet connection.

The absence of additional check marks signifies that WhatsApp has not yet confirmed receipt of the message by the recipient's device. Until the message reaches the recipient and is successfully downloaded to their phone, only one check mark will be visible. Once delivery is complete, you will see two check marks side by side, indicating that your message has been successfully delivered to the recipient's device.
