How to Use AI for Marketing Copy

Every marketer is using AI for copy. The ones whose copy still works don't use AI for the things that matter.

Where AI works for marketing

  • Subject lines — generate 10 variants, pick best
  • Ad-copy A/B variants
  • Cold email personalization at scale (with manual review)
  • Landing page outline

Where AI fails

  • Brand voice — gets 80% of way, last 20% destroys recognition
  • Product positioning — produces median version
  • Headlines that hit emotionally — needs human judgment
