Cold Email Lead Pipeline

The build

A high-volume cold email programme is killed by what goes into the sender, not the sender itself, so this build is the upstream half. A scheduled Apify scrape sources leads, and each one is checked against a tracking sheet before any API credit is spent on it. Snov.io resolves the company to a real domain and finds a verified work email; two of its endpoints run asynchronously, so a wait sits before the poll rather than reading a task handle as a result. Leads with no findable email are dropped instead of pushed downstream, one bad record routes aside rather than halting the batch, and survivors upsert into HubSpot so a re-run cannot duplicate them.
