Post office, what do you mean by sending me something and sending me a message?

Look at your express receipt. Is it more than the postage 1 yuan? By the way, this is the express SMS receipt service. When you send something, the salesperson adds this service to you. The function is that the system will send you a short message after the recipient signs for the email. But I can see from your question that the salesperson must have added this business to you on his own initiative without asking you at that time, which made you spend 1 yuan more. If you think this business is useful, it doesn't matter. If not, tell him that he doesn't need this business when he delivers it next time. Received two days later. Normal speed.
