  "summary": "The article discusses the use of transactional email and SMTP signals for 2FA codes and marketplace reports. It highlights that an email API can replace the SMTP login used by an application for 2FA codes and generated marketplace reports, but it does not replace the mail system beyond that submission boundary. The article emphasizes the importance of recording state transitions, such as queued, accepted, delivered, deferred, bounced, and complained, only when the transport supplies evidence for them. It also stresses the distinction between submission and outcome, and the importance of using different deadlines for 2FA codes and report delivery. The article concludes by noting that an HTTP API can replace application-side SMTP credentials, but the rest of the mail path still exists, authentication policy still matters, and asynchronous outcomes still need handling.",
