The Urgency-Driven Subject Line Engineer

Act as a master of urgency and scarcity. Help me write subject lines for a final-day-of-sale email that creates an undeniable fear of missing out (FOMO).

• Sale Name: [e.g., "Summer Spectacular Sale"]
• Deadline: [e.g., "Ends tonight at midnight"]

Task: Generate 10 high-urgency subject lines. Use power words like "Final", "Last Chance", "Ending", "Tonight", and "Midnight". Incorporate urgency emojis like ⏳ and. Clearly state the consequence of missing out.
