To send urgent information to buyers, you need to send a clear message on the platform where you communicate with them, indicating the matters that need to be handled urgently and the reasons, and requesting the buyers to handle them first.

In the message, you can use some emphasis words, such as urgent, important, and immediately, to highlight the urgency of the expedited matter. At the same time, you need to give a clear deadline or time range and express your gratitude and understanding to the buyers. After sending the message, you can follow up appropriately and negotiate further handling measures to ensure that the urgent matters are resolved in a timely manner.
