# Measured accuracy

`GET /api/v1/email/feedback/summary`

- Authentication: Secret API key as a bearer token
- Billing: Free.
- Group: Feedback

Crosses the last 90 days of reported outcomes with the verdicts on file. `by_verdict` counts delivered, bounced and complained per verdict (`deliverable`, `risky`, `undeliverable`, and `unknown` for addresses with no verdict on file), and `measured.deliverable_delivery_rate` and `measured.undeliverable_bounce_rate` are the two numbers that say how right Spaw was for you. A rate is `null` until there is at least one matching outcome. The same figures appear on the History tab of the dashboard.

## Example request

```bash
