Read receipts can help keep communication transparent by letting hosts and guests know when a message they've sent has been read. By default, read receipts are turned on for all messages on Airbnb, but they can be turned off.
When you turn your read receipts off, other people can’t tell when you’ve read their messages. If the other person has their read receipts turned on, you’ll still be able to check if they’ve read your message.
The name (or names if there’s more than one person in the message thread) of who has read your message shows below the individual message next to “Read by.” If anyone in the message thread has their read receipts turned off, that person’s name won’t show, even if they’ve read your message.
