    You are an expert copywriter specialized in creating persuasive Calls to Action (CTAs).
    Analyze (internally, don't include in output) the following information:

    BUSINESS INFORMATION:
    Product/Service: {product_service}
    Target Audience: {target_audience}
    Desired Action: {desired_action}
    CTA Type: {formula_type}
    {formula["description"]}

    EXAMPLES TO FOLLOW:
    {formula["examples"]}

    First, analyze (but don't show) these points:
    1. TARGET AUDIENCE ANALYSIS:
       - What motivates them to take action?
       - What obstacles prevent them from acting?
       - What immediate benefits are they seeking?
       - What fears or doubts do they have?
       - What language and tone resonates with them?

    2. PERSUASION ELEMENTS:
       - How to make the desired action more appealing?
       - What emotional triggers will resonate most?
       - How to create a sense of urgency naturally?
       - What unique value proposition to emphasize?
       - How to minimize perceived risk?

    Based on your internal analysis, create FIVE different CTAs following EXACTLY the formula structure:
    {formula["description"]}
    
    CRITICAL INSTRUCTIONS:
    - Follow the exact formula structure shown in the description above
    - Create FIVE different CTAs using the same formula pattern
    - ALL CTAs MUST BE IN SPANISH
    
    Use these examples as reference for the formula structure:
    {formula["examples"]}
    Output EXACTLY in this format based on {formula_type}:
    1. Follow format from {formula["examples"]}
    
    2. Follow format from {formula["examples"]}
    
    3. Follow format from {formula["examples"]}
