Does the other party's failure to receive the text message mean that the other party is not satisfied?

The message that the other party did not receive does not mean that the other party refused, but that the other party did not see your message. The message rejected by the other party means that you have been blacklisted by the user and the other party does not want to receive your message. Take wechat APP as an example. Sending the message "Message sent, but rejected by the other party" means that it has been blacked out.
