Do you want to send text messages before SF Express sends express mail to everyone?

However, it is limited to sending the courier to contact you twice when delivering the express mail, or sending a text message to the recipient from Monday to Friday when the customer is not at the receiving address.

If you are the sender and mobile phone number, you can choose the MSG service when sending the mail. After the express delivery is successful, SF will automatically give it to you.

The sender also sends a short message telling the sender that the delivery has been successful. There is no time limit for this.
