## What this rule covers
Buyer information should be used only as needed to fulfil an order or provide customer service. Sellers should not treat Amazon buyer data as a general marketing list.
## Why sellers should care
Misuse of buyer information can lead to policy action and can also create privacy and trust risks for the business.
## Common risk patterns
- Asking buyers for contact information that is not needed for the order
- Sending promotional messages or external links through buyer communication
- Exporting or sharing buyer information beyond the order-support purpose
## Safer operating practice
Use order-specific message templates, limit staff access to customer data, and review automation before it sends messages. Keep marketing campaigns separate from Amazon buyer communication unless Amazon expressly permits the activity.
## Important note
Privacy and messaging requirements can vary by marketplace and product type. Check current Seller Central guidance before changing a workflow.
