## How these metrics are calculated

<Note>
  Shared rules (inclusive date boundaries, unique vs raw counts, rate formulas) are documented once in [How Analytics Metrics Are Calculated](/api-reference/analytics/how-metrics-are-calculated).
</Note>

One row is returned per campaign. All metrics are scoped to emails **sent** within the date range (`sent_time`), inclusive on both ends; a single date returns that one full day.

| `sent` / `opened` / `replied` / `bounced` | Raw event counts within the range. Additive.                                                                                                                                                                                                                                                                                                                                              |
| `positive_replied`                        | Distinct leads tagged **positive** (`sentiment_type = 'positive'`). **Note:** the date attribution on this breakdown endpoint differs from the [`overall-stats-v2` tile](/api-reference/analytics/overview) (which is reply-date) — don't assume the two match for the same window. Use `overall-stats-v2` or the day-wise positive endpoints as the source of truth for positive counts. |
