Get campaign metrics

Unified engagement metrics returned by analytics endpoints. When a period or start/end filter is applied these are a funnel over the sends made inside that window, not a log of events inside it: every delivery, engagement, and reply count is attributed to one of those sends, including activity that arrives after the window closes, so opened <= delivered <= sent always holds and no rate can exceed 100%. conversions and revenueCents are the exception and use the goal's own last-touch attribution window. Open and click metrics exclude detected scanner, preview, and tracked asset events unless includeMachineEngagement is true.

Lifetime per-link click breakdown, most clicked first (top 20). Omitted when the campaign has no tracked link clicks.

Lifetime Poll and NPS summaries. Omitted when the campaign has no responses.

Product recommendation funnel for a campaign or sequence. Returned as a top-level recommendations object when recommendation blocks were rendered. The requested period or custom time range scopes impressions and clicks. Orders and revenue are attributed when a subscriber buys a recommended product within 7 days of a scoped click.
