Hey guys, just posted a full walkthrough of how I build a hyper-targeted cold email list in under 20 minutes using Apollo, Boomerang, and Clay. Cover the three phase workflow from targeting to scraping to enrichment, how to calculate the right scrape volume to account for verification drop-off, the full Clay enrichment run including ZeroBounce, website scraping, and Claude AI personalisation, and the most common mistakes including over-scraping and exporting without checking the personalisation lines. https://youtu.be/g8wrJdUC3SY
