+To use this code:
+
+1. Create a `.env` file in the root directory with your configuration:
+```env
+API_KEY=your_api_key
+OPENAI_API_KEY=your_openai_api_key
+DATABASE_URL=your_database_url
+SECRET_KEY=your_secret_key
+```
+
+2. Install the requirements:
+```bash
+pip install -r requirements.txt
+```
+
+3. Run the API:
+```bash
+uvicorn api.endpoints:app --reload
+```
+
+This code provides a foundation for:
+- Processing and analyzing CRM data
+- Generating marketing content using AI
+- Answering NLP and Timeline Therapy questions
+- Securing the application
+- Validating data
+- Exposing functionality through API endpoints

+        Template - 1:
+        Dear friend,
+
+        As we approach the final days of 2024, I wanted to reach out with a message of hope and possibility for the year ahead. The dawn of 2025 brings with it an opportunity not just for fresh starts, but for transformative growth and achievement.
+        You may have already begun thinking about your aspirations for the coming year. Whether you have or haven't, I'd like to personally invite you to join me for an intimate goal-setting session where we'll work together to crystallize your vision for 2025.
+        I believe that every remarkable success story begins with clarity - knowing exactly what you want and placing it firmly in your future Time Line in a way that makes it inevitable. This isn't just about writing down wishes; it's about crafting the blueprint for your next chapter.
+        Before our session, I encourage you to reflect on three crucial questions:
+
+        1. What is the most important achievement you envision for 2025?
+        2. How can you leverage your unique experiences and skills to create positive change in the world?
+        3. What stepping stones will you need to place along your path to ensure your primary goal becomes reality?
+
+        Here's what makes this journey so powerful: as you pursue specific goals, you naturally develop new skills, strategies, and behaviors. Sometimes, achieving a goal requires you to become an entirely new version of yourself - and that transformation is often the most valuable reward of all.
+        Join me for this complimentary goal-setting session:
+        Date: Thursday 15 January 2025
+        Time: 4pm AEDT
+        Register Today
+        The more attention you invest in this process, the more you'll free yourself from limitations, unleash your creativity, and uncover possibilities you never imagined. This creates a beautiful cycle: greater goals lead to greater successes, which build self-confidence and positive momentum.
+        Register today for this special session. I look forward to helping you lay the foundation for an extraordinary 2025.
+        Be Well!
+
+        Template - 2:
+        Hi [[contact.first_name]],
+        I trust you've been putting the valuable insights from our recent Goal-Setting Masterclass to good use. I hope you've had a chance to dive into the videos and set your sights on exciting goals for 2025 across all areas of your life -career, relationships, finance, health, and beyond.
