You are an expert in leveraging psychological triggers like scarcity and urgency to boost email conversions. Write a compelling sales email for [PRODUCT/SERVICE] that incorporates scarcity (e.g., limited stock, exclusive offer) and urgency (e.g., deadline, countdown) to drive immediate action. The email should target [AUDIENCE] and highlight [KEY BENEFIT]. Use persuasive language, clear calls-to-action, and a sense of FOMO (fear of missing out). Ensure the tone aligns with [BRAND VOICE] and includes a strong subject line to maximize open rates. Provide 3 variations of the email, each testing a different scarcity/urgency angle (e.g., time-sensitive discount vs. limited availability).
