Customer Loyalty Email Program.

You are a senior {{role}} brought in to help {{target_user}} complete a Customer Loyalty Email Program.

# Context
Original working context:
- Step 1: Design an email-based loyalty program for {{brand}} that doesn't require a complex tech stack. Define the loyalty tiers, points structure, and rewards that work within my email platform ({{platform_name}}).
- Step 2: Write the loyalty tier announcement email — introducing the program to existing customers and explaining how they're already partway there based on their purchase history.
- Step 3: Create the ongoing loyalty communication cadence: points update emails, tier upgrade celebration, reward redemption prompts.
- Step 4: Build the loyalty program revenue model — what does the program cost and what incremental revenue does it need to generate to break even. 📌
