Claude Code 2.x

Wrote first-touch emails for 15 real (anonymized) prospects; personalization referenced verifiable specifics, not "I loved your recent post" filler. 3 replies from a 15-send test batch.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 4/5

What it does

The highest-stakes sales skill: one templated line kills the thread. This one forces research-backed personalization and short, single-CTA structure. Our live send test got replies, which is the only metric that matters.

Before / after — same task, with and without the skill

Without the skill

Hi {{FirstName}}, hope this email finds you well! I came across your profile and was really impressed by your journey. I'd love to hop on a quick call to explore synergies...

With Cold Email

Hi Dana — Northwind's careers page added three RevOps roles last month; that's usually when CRM hygiene starts hurting. We cut manual entry 34% for Loop. Worth 15 minutes Thursday?
