Node.js Transactional Email APIs: Owning Templates for Password Resets and Seller Alerts

For Node.js transactional emails like password resets or seller alerts, developers should use APIs that export delivery events and stable message IDs. Implementing a replaceable adapter behind a queue ensures flexibility. Keeping message templates within the application repository allows for better versioning, testing, and code reviews. Crucially, expiry timestamps, redemption records, and compliance audit trails must be maintained in the internal system rather than relying solely on the email provider's API for record keeping.
