The Challenge

Manual scraping slowed down outreach

The team had a large list of target websites but no efficient way to collect emails and update their lead sheet.

  • Researchers copied data site by site
  • Lead lists went stale quickly
  • No consistent validation or status tracking
The Solution

Automated crawling and sheet updates

We built a lead scraper that visits each target website, extracts emails, validates results, and updates a shared sheet automatically.

  • Batch processing across large URL lists
  • Email extraction with domain matching
  • Sheet updates with status and confidence
  • Retry logic for blocked or missing pages
“We went from manually chasing emails to a clean, updated lead list every morning. It unlocked a huge amount of outreach capacity.”
