Technical details
Endpoint
GEThttps://mpp.api.agentmail.to/v0/inboxes/:inbox_id/metrics?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need time-series analytics on email activity for a specific AgentMail inbox — ideal for monitoring delivery health, detecting bounce spikes, or auditing message volume over a custom time window. Prefer this over general inbox listing endpoints when the goal is aggregated counts and trends rather than individual message details.
