Pipeline

Personalize β€” variable substitution in templates ({name}, {company}, {pain_point}) 4. Send β€” via Resend, SendGrid, or raw SMTP with rate limiting 5. Drip β€” automated follow-ups at day 3 and day 7 6. Track β€” log all sends, bounces, replies to CSV/Sheets

Requirements

  • Email provider API key β€” Resend (RESEND_API_KEY), SendGrid, or SMTP credentials
  • Verified sending domain β€” with SPF, DKIM, DMARC configured
  • Lead source β€” CSV file, Google Sheet ID, or API endpoint

node scripts/cold-email-engine.js --source leads.csv --template templates/default.txt --dry-run
    Run drip follow-ups
    
node scripts/cold-email-engine.js --drip --days 3
