Will Tmall send a text message to the consignee when it cancels the order?

No. According to the cancellation rules of Tmall Supermarket, the order status of Tmall Supermarket will be synchronized to the consignee's mobile phone. When the order is cancelled, the status will be updated to cancelled order, and the consignee can check the order status on the mobile phone. If the order status is shipped, you can cancel the order. After canceling the order, the system will notify the user by SMS, but not the consignee. Therefore, if the user cancels the order, the consignee will not receive SMS notification.
