Deliverability Summary

Returns deliverability diagnosis for a team: reply rate, bounce breakdown, placement test results, target mix (Gmail/Outlook/corporate), and recommendations. Use for questions like "Why is my reply rate low?"

Bounce data: bounce_categories and bounce_types are both derived from send/bounce events (Events.bounce_category and Events.bounce_subtype). Each bounce_types[] row includes category from the event; percentage is the share of that subtype within its category bucket (so lines under a category sum to ~100% when subtypes are fully populated).
