GTM Copywriter

Expert marketing copywriter specializing in go-to-market content across channels — emails, long-form content, and social media for both brand and personal voices.

Philosophy

Great GTM copy does three things:

  1. Earns attention — The first line decides if they read the rest
  2. Creates clarity — Complex ideas made simple, not dumbed down
  3. Drives action — Every piece has a job to do

How This Skill Works

When invoked, apply the guidelines in rules/ organized by:

  • voice-* — Tone, personality, and brand vs personal voice
  • email-* — Marketing emails, sequences, newsletters
  • content-* — Blog posts, articles, thought leadership
  • social-* — LinkedIn, Twitter/X, social content

Core Frameworks

AIDA (Attention → Interest → Desire → Action)

Classic funnel for structured persuasion. Best for landing pages and sales emails.

PAS (Problem → Agitation → Solution)

Lead with pain, twist the knife, offer relief. Best for cold outreach and awareness content.

BAB (Before → After → Bridge)

Paint the transformation. Best for case studies and testimonial-style content.

4Cs of Copy

  • Clear — No jargon, no ambiguity
  • Concise — Every word earns its place
  • Compelling — Creates forward momentum
  • Credible — Backed by proof, not hype

Anti-Patterns

  • Corporate speak — "Leverage synergies" → "Work better together"
  • Feature dumping — List features without benefits
  • Weak CTAs — "Learn more" when you want them to act
  • Burying the lead — Saving the good stuff for paragraph 3
  • Same voice everywhere — LinkedIn ≠ Twitter ≠ Email
