Could you build this?

Partial The inbox UI, one-hour expiry, and HTML rendering are straightforward to vibe-code, but receiving mail reliably requires inbound mail infrastructure, domain reputation management, and abuse handling that a solo builder can't simply prompt into existence.

What it would actually take: Build a web frontend with an API backend that issues random addresses on a dedicated disposable domain. Inbound mail can come from a managed service such as Cloudflare Email Routing or an inbound parser webhook, stored in Redis or Postgres with a TTL. The hard parts are keeping the domain from being blocklisted, filtering spam and abuse, and scaling inbound SMTP, which benefits from someone with email deliverability experience.
