Could you build this?
Partial The API, SMTP endpoints, and suppression and verification logic are buildable with AI assistance, but reliable delivery depends on sending infrastructure, IP and domain reputation, and ISP relationships that take years to establish.
What it would actually take: The stack would be an SMTP and HTTP API layer in front of a transactional sending backend, using a queue, bounce and complaint webhooks, suppression lists, and a verification service such as MX and SMTP probing. The hard parts are deliverability (warm-up, reputation management, DKIM, SPF, DMARC enforcement) and abuse prevention. That requires email-operations expertise and dedicated IP infrastructure, or reselling an existing provider such as SES or Postmark.
