# NotificationDeliveryOutcomeSummaryDto

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

How many deliveries ended in each state inside a window, for the merchants the caller's operating
context reaches. Answers "how much did you drop while we were unreachable" without paging a grid
once per status.

## Fields
- `fromUtc` (string(date-time)): Start of the counted window, inclusive, in UTC.
- `toUtc` (string(date-time)): End of the counted window, exclusive, in UTC.
- `pending` (integer(int64)): Deliveries created but not yet picked up by a processor: still queued on this side.
- `processing` (integer(int64)): Deliveries in flight when the window was counted.
- `succeeded` (integer(int64)): Deliveries the destination acknowledged. The "delivered" number.
- `failed` (integer(int64)): Deliveries that failed an attempt and may still be retried.
- `deadLettered` (integer(int64)): Deliveries that exhausted every retry and were dead-lettered.
- `skipped` (integer(int64)): Deliveries never attempted, because the destination was suppressed or another policy gate  stopped them. The closest thing this platform has to "discarded".
- `total` (integer(int64)): Every delivery in the window, in any state. (read only)
