What does one checkmark in WhatsApp mean when sending a message - in detail?
When you send a message on WhatsApp, the appearance of a single checkmark indicates that your message has been successfully sent from your device to WhatsApp's servers. This initial checkmark serves as a confirmation that your message is now undergoing transmission through WhatsApp's infrastructure and is not yet delivered to the recipient's phone. It is important to note that at this stage, the message has left your device but may still be in transit, awaiting delivery to the intended recipient. The single checkmark does not provide information about whether the recipient has viewed or read the message; it merely signifies that WhatsApp has accepted and begun processing your communication for delivery.
