This article explains how to track your WhatsApp messages using two colored check marks to see when a message has been sent, received, and read. It also explains how to turn off read receipts.

Checkmarks on WhatsApp appear to the right of each of your messages. When you send your message, it will be marked with a single gray checkmark. When the message reaches your recipient’s device, you’ll see a second gray checkmark, and when the recipient reads your message, the checkmarks will turn blue.

Group messages use the same system, but they are a little different. When you send a group message, you will only get the double check marks if the message has been delivered to all members of the group. Likewise, the double check mark will only turn blue after all members of the group have seen the message.

If you’re wondering why your recipient didn’t read your last message, you can dig a little deeper and find out more. At the top of your message thread, you’ll see your recipient’s name and the last time they were online. It’s possible that they haven’t been online since you sent the message, or that they’ve blocked you.
