The seller shouldn’t have had her email address. Sellers who fulfill orders themselves do receive customer names and mailing addresses. But for orders that Amazon itself fulfills, customer data is supposed to be shielded from sellers and brands.

Sellers are permitted to communicate with buyers through Amazon’s built-in messaging platform, which hides the customer’s email address. Amazon’s terms of service also prohibit sellers from requesting that a customer remove a negative review or post a positive one.

“We do not share customer email addresses with third-party sellers,” an Amazon spokesman told me.

Meanwhile, brands, which can be distinct from sellers, may reach out to unsatisfied customers through Amazon’s messaging service, but they also aren’t allowed to ask customers to remove negative reviews.
