## How these metrics are calculated

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

| Field              | How it's calculated                                                                                                                                                                                                |

| `positive_replied` | `COUNT(DISTINCT lead)` for leads tagged as **positive** (`sentiment_type = 'positive'`) that sent a genuine reply (replied, not ignored, not bounced), bucketed by the day their email was **sent** (`sent_time`). |

This is the **send-date** view of positive replies — use it to see which *sending* days produced positive replies. It differs from the [day-wise positive endpoint](/api-reference/analytics/day-wise-positive-reply) and the `overall-stats-v2` tile, which attribute positives to the **date the reply was received**; a reply that arrives days after the send lands on a different day across the two views.

`positive_replied` is a **distinct-lead** count. The lead category is mutable, so re-categorising a lead changes historical days. Dates are inclusive on both ends — `sent_time >= start 00:00:00 AND sent_time <= end 23:59:59` — and a single date returns that one full day.
