Type-safe email metric calculation

Stop worrying about malformed API responses. When your agent runs `calculate_delivery_metrics`, Pydantic AI checks the result against a strict schema to ensure your data is always valid. If the numbers don't match your expected format, the agent fails immediately. This prevents bad data from polluting your marketing reports.

Verified engagement and revenue data

Use `calculate_engagement_metrics` to get reliable stats on your email campaigns. Every response is validated at runtime, so you know exactly what your click-through rates are. Following that, use `calculate_revenue_metrics` to get your final dollar totals. Because you are using Pydantic AI, you get absolute confidence in every calculation.

Benchmark data with confidence

Pulling external benchmarks via `get_industry_benchmark` is now safe and predictable. The tool output is strictly typed, so your agent handles the data without any surprise field errors. This is the right way to manage email performance if you care about correctness. It keeps your agent logic sound and your reporting accurate.
