Could you build this?

Partial The shared inbox, automations, SDK and MCP layer are vibe-codeable. Reliable custom-domain email needs SMTP/IMAP infrastructure, deliverability management and abuse handling, which are hard to get right without specialist operations expertise.

What it would actually take: The app layer would sit on an existing mail infrastructure provider or a self-run MTA such as Postfix or Stalwart, with DNS automation for SPF, DKIM and DMARC. The hard parts are sender reputation, IP warm-up, bounce and spam handling, and security at scale. Building it well requires email deliverability and operations expertise plus ongoing abuse-response capacity.
