discuss I am contacting the same member again and again by accident

I have a problem here in the forum

I send private messages to many buyer requests. I keep sending to the same buyers again and again because I can not remember that I already did that before . I do not remember the member names or my history with them

Can you change the message system to be like Facebook messenger. If you send again to same person ,Old messages appear .

Anyone have the same problem

It is very difficult for me to search all old messages to see if I have sent to this buyer before

And it is annoying and embarrassing to accidentally send the same domains to same buyers again and again
