Could you build this?

Partial The API, templates, and delivery-timeline UI are vibe-codeable, but a credible sender must handle SMTP delivery, deliverability, IP and domain reputation, and bounce handling, which require operational expertise beyond vibe coding.

What it would actually take: A real version would sit on a provider such as AWS SES or a self-run MTA, with webhook ingestion for delivery events and a timeline store. The hard parts are inbox placement, reputation management, and compliance with bounce and complaint handling, which require email-deliverability operations experience.
