Could you build this?
Partial Shared inbox UI, workflows and agent connections are buildable on top of an existing email API. Delivering email at scale with good deliverability depends on sending infrastructure, IP warm-up and reputation management that vibe coding can't supply.
What it would actually take: Build the inbox UI, threading, and workflow engine on an email provider API such as SES or Postmark, with webhooks for inbound mail and an agent integration layer. The hard parts are deliverability (SPF/DKIM/DMARC, IP reputation, bounce and complaint handling) and scale, which require email-ops expertise and dedicated infrastructure.
