The overwhelming consensus from email marketers, experts, and Amazon's official documentation is that using marketplace.amazon.com email addresses for marketing opt-ins is illegitimate and highly discouraged. Amazon strictly prohibits using buyer-seller messaging for marketing purposes, and harvesting email addresses for external campaigns violates Amazon's terms of service. These addresses are intended for transactional communication, not marketing. Unsolicited marketing emails are considered spam, potentially violating anti-spam laws like CAN-SPAM, and can lead to account suspension, blacklisting, or legal repercussions. Legitimate opt-in requires explicit and informed consent obtained independently of the Amazon platform. Ethically, such practices violate user expectations and data privacy.
