Pro Tips for Best Results

  • Test subject lines with your actual audience using A/B testing to find what resonates best
  • Avoid excessive punctuation (!!!!) and all caps as they trigger spam filters
  • Include numbers and percentages when promoting discounts - they catch the eye in crowded inboxes
  • Keep the most important words in the first 30 characters since many email clients truncate longer subject lines
  • Use preview text strategically to complement your subject line and provide additional context
