What it does

Writes B2B cold outreach emails, subject lines, and multi-touch sequences designed to get replies. Reach for it when prospecting, running SDR campaigns, or when your cold emails aren't working. Focuses on personalization and natural voice—avoids the AI tells and generic structures that kill reply rates.

  • Craft opening lines and body copy that feel conversational, not salesy
  • Build multi-touch follow-up sequences that respect the prospect's inbox
  • Personalize based on research signals (funding, hiring, tech stack, LinkedIn activity)
  • Pull from product-marketing context to align outreach with your actual value prop
