What this solves

Agents invent bad cold email habits unless you give them real playbooks. This pack encodes deliverability and copy rules so Claude Code reviews and writes outreach the right way.

Inbox first

Missing SPF/DKIM/DMARC or HTML-heavy first touches kill campaigns before copy matters.

Human copy

Banned phrases and AI-slop patterns get rejected. Conditional Questions replace hard meeting asks.

Agent-ready

Drop into .claude/skills/ and ask in plain English — no custom scaffolding required.

What's in the pack

Three skills. Copy them into any Claude Code project.

GTM Outreach

.claude/skills/gtm-outreach/

Entry router for any cold outreach task. Points the agent to deliverability or copywriting based on what you ask.

  • When to use which skill
  • Outreach mental model
  • Non-negotiables before send

Cold Email Deliverability

.claude/skills/cold-email-deliverability/

Inbox placement first. DNS auth, plain-text defaults, ESP/SEG awareness, and a pre-send checklist.

  • SPF / DKIM / DMARC audit
  • Plain-text sending defaults
  • SEG awareness (Proofpoint, Mimecast, etc.)

Cold Email Copywriting

.claude/skills/cold-email-copywriting/

Hook → Bridge → CTA structure, banned-phrase rules, and the Conditional Question framework for first-touch CTAs.

  • Stain-remover-pen framing
  • Banned AI-slop phrases
  • Conditional Question CTAs

Knowledge files

Extra depth the copywriting and deliverability skills load when needed.

banned-phrases.mdReject spam triggers, fluff openers, and AI-sounding patterns
