About WhatsApp Read Receipts
WhatsApp Read Receipts look like checkmarks.
When you send a message, a grey checkmark appears next to the time stamp.
Two checkmarks appear upon delivery to the recipient.
When the recipient reads it, two blue checkmarks appear.
In a group chat, both checkmarks turn blue after every participant of the group chat opens the message.
Read receipts are a two-way street.
If you turn off read receipts, you won’t be able to tell when others have read yours.
