Can I send text messages after Taobao blacked out?

Taobao and WeChat chat have similar interfaces, but there is a little difference. Of course, after joining the blacklist, the message will not be sent! But unlike WeChat, what you send to the other party can also show what you have sent in the past, instead of showing the rejection information of the other party. I just don't know if the other party really received it, but what is certain is that you will definitely not receive the message sent by the other party!
