As part of selling on Amazon, sellers communicate with buyers both directly and indirectly. Amazon requires that sellers follow certain guidelines when communicating with buyers.
In any communication you have with buyers (including shipping box inserts), you cannot ask them to leave a positive customer review for your product, or to leave a review only if they had a positive experience with your product. Similarly, you cannot ask only customers who had a positive experience with your product to leave a review. It is also prohibited to offer them any compensation for a review, including money or gift cards, free or discounted products, refunds or reimbursements, or any other future benefits.
For more information, please review Amazon's guidelines in Customer product reviews policies.

These updates include information such as when an order has been shipped (with the tracking number) or when a refund has been processed. These updates are based on shipping confirmations and refunds initiated using Manage Orders or the following feeds:
In general, you may contact a buyer who has purchased from you on Amazon only for the purposes listed above or to complete an order or to respond to a customer service inquiry.

If you send a permitted email to a buyer, your email may not include any of the following:
Be sure to include the Amazon order ID in your communications to buyers and on the shipment packing slips.
Amazon also restricts sellers from using customer information, such as their email or postal addresses, for any purpose other than for sending order-related emails or shipping orders. Any other communication through unsolicited emails, postal mails or telemarketing phone calls is strictly prohibited. Sellers must include the Amazon order ID in all communication with customers and also on the packing slip included in the shipment.
If you have questions about our policies regarding communicating with buyers, contact Seller Support.
