A single blue tick on WhatsApp is an indicator that your message has been successfully delivered to the recipient. This doesn’t mean, however, that the recipient has seen or read it. It just means that the message was transferred from your device to the recipient’s device.
WhatsApp has two kinds of “ticks” that appear next to messages you send: a single grey tick and a double blue tick. The grey tick indicates that your message is still in the process of being sent, while the blue ticks indicate that it has been delivered.
If you see one blue tick, it means that your message was successfully delivered to the recipient’s device. However, it does not necessarily mean that they have seen or read it yet. It could be that they simply haven’t opened up the app yet or even disabled notifications for incoming messages.
The double blue ticks on WhatsApp indicate two things: firstly, that your message was successfully delivered and secondly, it implies that the recipient has seen or read your message as well. This is because when someone opens up WhatsApp and reads a previously unread message, both ticks turn blue.
It’s important to remember though that you can’t always rely on this feature to determine whether someone has seen or read your messages; some people may have notifications disabled, while others may be using a different messaging app altogether.
Conclusion
In conclusion, a single blue tick on WhatsApp indicates successful delivery of your message but doesn’t guarantee whether or not it has been seen or read by the recipient. The only way to determine this would be if you receive double blue ticks instead.
