cost_drivers:

  - driver: Subscriber Count
    description: Kit pricing is subscriber-based. The total number of active email subscribers on the account determines the monthly or annual bill across all plans.
    notes:
      - Free Newsletter plan supports up to 10,000 subscribers.
      - Creator and Pro plans start at 1,000 subscribers and scale upward.
      - Costs increase incrementally as subscriber thresholds are crossed.

  - driver: Plan Tier
    description: Plan selection (Newsletter, Creator, Pro) determines feature access and base price.
    notes:
      - API access is available on all plans.
      - Advanced analytics and team features only on Pro.
      - Kit MCP (AI integration) and SMS marketing on Creator and Pro.

  - driver: Billing Frequency
    description: Annual billing provides approximately 16% savings versus month-to-month.
    notes:
      - Monthly Creator plan starts at $39/mo; annual equivalent is $33/mo.
      - Monthly Pro plan starts at $79/mo; annual equivalent is $66/mo.

optimization:

  - strategy: Choose Annual Billing
    description: Commit to an annual plan to reduce per-month costs by ~16%.

  - strategy: Monitor Subscriber Growth
    description: Track subscriber counts proactively to anticipate tier crossings and budget increases.

  - strategy: Use API Keys for Low-Volume Integrations
    description: API Key auth (120 req/60s) is sufficient for most automation use cases and avoids OAuth implementation overhead.

  - strategy: Use OAuth for High-Volume Integrations
    description: OAuth auth (600 req/60s) allows 5x more throughput, reducing the need for request batching or retry logic at scale.

  - strategy: Leverage Bulk Endpoints
    description: Use bulk operation endpoints (OAuth required) to reduce total API call volume and stay within rate limits.

  - strategy: Start on Free Newsletter Plan
    description: The free tier supports up to 10,000 subscribers, making it cost-effective for early-stage list building with API access.
