Broadcast analytics summarize what happened from audience selection through email delivery and engagement. ## Core metrics A broadcast can report: * `audience` — contacts captured from the selected segment * `eligible` — contacts that remained after eligibility checks * `excluded` — contacts removed before delivery * `queued` — recipient emails queued for delivery * `delivered` — messages reported delivered * `bounced` — messages reported bounced * `complained` — messages associated with a complaint * `failed` — recipients or messages that failed * `opened` — recipients with an observed open event * `clicked` — recipients with an observed click event ## Audience metrics The difference between `audience` and `eligible` represents contacts removed by audience eligibility rules. Use the exclusion summary to inspect counts grouped by reason, such as global unsubscribe, suppression, invalid email, or topic opt-out. ## Delivery metrics `queued` represents recipients handed off to the normal email delivery pipeline. Delivery outcomes can then change independently for each recipient. A lower delivered count than queued count does not necessarily indicate a fanout problem. Some messages may still be in progress, while others may later bounce or fail. ## Engagement metrics `opened` and `clicked` summarize tracked engagement events associated with the broadcast's email messages. Treat these metrics as observed signals rather than perfect measurements. Email client privacy features and tracking behavior can affect whether open events are visible. ## Recipient-level investigation Aggregate analytics are best for understanding the overall result. When you need to investigate a specific address, use the broadcast recipient list and the linked email message where available. Review how recipients become eligible or excluded before fanout.
