We sent 1,023,345 cold emails last year. Here’s what works.
Over the last 12 months, those emails booked 2,136 sales calls for us (not counting client campaigns).
I just dropped a new YouTube breakdown.
Here’s a quick taste:
  1. Specificity > Crazy Promises “We’ll get you more clients” is dead. When we got ultra-specific (niche, offer, deal size, packages, who their clients are), reply rates and trust went up without screaming 100-call guarantees.
  2. Lead Efficiency = Hidden Goldmine We took positive reply → booked call from 15% to 35%
  3. AI Personalization Or You’re Toast In 2026 Even “basic” AI-powered personalization (site/product/case study/tier references) more than doubled positive replies vs. non-personalized sends. When it’s relevant to what you sell, it’s even bigger.
In the video, I walk through:
  • Real campaigns (generic vs hyper-specific)
  • The exact follow-up system we use to squeeze maximum calls from every positive reply
  • How we’re using AI to personalize at scale without writing 1,000 custom emails by hand
