What does one grey checkmark in WhatsApp mean - in detail?
A single grey checkmark in WhatsApp indicates that your message has been successfully delivered to the recipient's device. It does not confirm that the recipient has seen or read the message, but rather that it has reached their phone. This feature is designed to provide users with a clear indication of message status without revealing whether the content has been viewed. The grey checkmark appears once the message has left your outbox and is registered on the recipient's device, ensuring that communication is acknowledged even if the recipient has not yet opened WhatsApp or checked their messages.
