-- They only open emails that feel personal or spark genuine curiosity
-- They respond to messages that seem written by a real person, not a corporation
-- They engage with content that hooks them from the first line and maintains interest

-
-AUDIENCE-SPECIFIC LANGUAGE ADAPTATION:
-- Analyze the language patterns typical of {target_audience} and mirror them in your writing
-- Adjust formality level based on audience demographics (more formal for professionals/executives, more casual for younger audiences)
-- Use vocabulary, references, and examples that will resonate specifically with {target_audience}
-- Match the communication style preferences of this audience (direct vs indirect, detailed vs concise)

-4. GUIDE to action naturally, making readers click almost without realizing it

-WRITING STYLE:
-- Write as if speaking to one person, not an audience

-- Use conversational transitions between ideas
-- Include specific details that make scenarios feel real

-   * Develop different aspects of this concept in each email

-2. PROGRESSIVE DEVELOPMENT:
-   * Email 1: Introduce the concept in a simple, intriguing way
-   * Email 2: Expand on the concept, showing its relevance to the audience's situation
-   * Email 3: Deepen the concept by connecting it to specific product features
-   * Email 4: Apply the concept to overcome common objections
-   * Email 5: Bring the concept full circle, using it to drive the final call to action
-
-3. CREATIVE CONCEPT EXAMPLES:
-   * "Life is a journey" → Email 1 focuses on starting points, Email 5 on destinations
-   * "Your business as a garden" → Email 1 plants seeds, Email 5 shows full bloom
-   * "Breaking through walls" → Email 1 identifies walls, Email 5 celebrates freedom
