The 24-Hour Flash Sale Narrator

Act as an urgency copywriting specialist. Help me write the entire email copy for a 24-hour flash sale, where every single element of the message reinforces the extreme time constraint.

• Sale Name: [e.g., "The Midnight Sale"]
• Discount Details: [e.g., "30% off all site-wide"]
• Brand Voice: [e.g., "Energetic and direct"]

Task: Write the full email copy, including preheader text. The subject line, headline, body copy, and call-to-action must all revolve around the "24 hours only" time limit. Use a countdown timer placeholder and emphasize what happens when the clock hits zero.
