Could you build this?
Partial The UI and the syntax, MX, and disposable-domain checks are easy, but reliable SMTP verification at scale needs many clean IPs and reputation management that vibe coding won't provide.
What it would actually take: The stack is a job queue with workers doing DNS MX lookups, SMTP handshake probes, and disposable-domain lists, with results stored and exported. The hard part is SMTP verification at volume, since mail servers throttle or block probing, so the product needs rotating IP infrastructure, rate-limit handling, and accuracy tuning. That requires email-deliverability operations expertise and ongoing infrastructure work.
