# Context
Original working context: Design a personalization strategy for {{brand_name}}'s email program. My email platform: {{platform}}. Data I have access to: {{list}}. Create: (1) a personalization ladder — from basic (first name) to advanced (dynamic product recommendations), (2) the specific personalization tokens and merge tags to use in each email type, (3) the fallback logic when personalization data is missing, (4) 3 personalized email examples showing what the email looks like for different customer segments, and (5) the data collection strategy to enable more advanced personalization over time. 📌

# Goal

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.
