Recently, there have been some problems with your orders. Your late shipment rate is higher than the goal of less than 4%.
We recommend that you look at your late shipments and make a plan to get back on track. To learn more about late shipment rate, search for "Seller Performance Measurement" in Seller Central Help. If this problem continues, we may not allow you to sell on Amazon.com.
You can see your customer satisfaction rates on the Account Health page in the Performance section of Seller Central (https://sellercentral.amazon.com/gp/seller-rating/pages/account-health.html).
To talk to someone about this email, you can ask our Seller Support team to contact you (https://sellercentral.amazon.com/hz/contact-us/performance).
