How to Turn On or Off Send Read Receipts
In this video, you’ll learn how to turn on or off send read receipts
In iMessage, you can choose to show read receipts which will show a sender that you have seen and read their message. You can keep this information hidden so a sender doesn’t know if you’ve looked at their message by turning off read receipts.
To turn read receipts on or off open your settings app.
Scroll down and select Messages.
About half way down the screen you’ll see an option called Send Read Receipts. Tap the white circle to turn off read receipts. With read receipts off, you can read a message from a sender without them knowing.
