What does one checkmark mean when sending a message in WhatsApp - in detail?
When you send a message on WhatsApp, the presence of a single checkmark (✔) indicates that your message has been successfully sent from your device to WhatsApp's servers. This status update is visible only to the sender and not to the recipient. It serves as an initial confirmation that the message has left your phone and is in transit through WhatsApp’s network infrastructure.
This single checkmark does not provide any information about whether the recipient has received or read the message; it merely confirms that the message was sent successfully from your end. If you do not see this checkmark, it could indicate a problem with your internet connection or an issue with WhatsApp’s servers.
In summary, seeing a single checkmark after sending a message on WhatsApp means that your message has been transmitted to WhatsApp's servers and is on its way to the recipient.
