## 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 client, aggregating every campaign that belongs to that client. 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.
