If the imessage message has been read, will there be a prompt?

When the other party reads the iMessage message, if the sender turns on the "Send Read Receipt" function, then the sender will receive a read prompt. This prompt is usually displayed under the sender's chat window information in the form of "read".

It should be noted that this function is set by the user. If this function is turned off, even if the other party reads the information, the sender will not receive any prompt. Therefore, if you want to know whether the other party has read the information, you need to make sure that the "Send Read Receipt" function is turned on.
