Subject Line Optimization Tips

  • Match Goals & Tones: Casual is best for cold outreach, while professional is suited for B2B updates and follow-ups.
  • A/B Test Categories: Test a Curiosity Gap subject line against a Benefit-Driven line. Different lists respond to different psychological anchors.
  • Check Mobile Widths: Over 60% of emails are read on mobile. The Short & Punchy lines guarantee your full subject isn't truncated on small screens.
  • Personal placeholders: Use the [First Name] tags generated in your email marketing service (e.g. Mailchimp, HubSpot) to automatically personalize deliveries.
