Could you build this?
Partial Parsing CSVs and basic deduplication/regex validation is trivial, but true email verification requires maintaining SMTP handshake workers, handling catch-all domains, and avoiding blocklists at scale.
What it would actually take: A functional email verification backend uses asynchronous worker queues (Celery/BullMQ) that perform DNS/MX record lookups, disposable email domain filtering, and direct SMTP conversation handshakes ('RCPT TO') without sending actual mail. The hard part is managing large rotating pools of clean residential/datacenter IPs, managing rate limits per mail provider (Google, Microsoft, Yahoo), and preventing ISP blacklisting. This requires dedicated deliverability infra and network engineering.
