Could you build this?

Partial The developer-facing API, SDK, and MCP server are easy to vibe-code, and the service could wrap an existing sending provider. Real deliverability, domain reputation, and bounce/complaint handling take infrastructure and operational expertise.

What it would actually take: Build a REST API and SDKs on top of SMTP or an upstream provider such as SES, with domain verification (DKIM/SPF/DMARC), webhooks for delivery events, and an MCP server wrapper. The hard parts are deliverability (IP warm-up, reputation management, feedback loops, suppression lists) and compliance, which require email-infrastructure experience and time to build trust.
