# Performance & Logs

> See delivery, open, click, and error rates for a broadcast, and inspect every send in the per-recipient log.

Every broadcast you send has a **Performance** tab. Open the broadcast and select it to see how the send did, from the top-line rates down to what happened for each recipient.

## Aggregate metrics

The top of the Performance view summarizes the whole send:

| Metric            | What it shows                                |
| ----------------- | -------------------------------------------- |
| **Total sent**    | The total number of messages sent.           |
| **Delivery rate** | The percentage of sends that were delivered. |
| **Open rate**     | The percentage that were opened.             |
| **Click rate**    | The percentage that were clicked.            |
| **Error rate**    | The percentage that errored.                 |

<Note>
  The metrics you see depend on the channel. Open and click tracking only applies to channels that support it, like email.
</Note>

## Per-recipient log

Below the summary, the log lists every recipient in the send with a timestamp, the recipient, and the status of their message. Filter by status (**All**, **Delivered**, **Opened**, **Clicked**, or **Errors**) or search for a specific recipient.

When something looks off for one person, this is where you find them. Open the row's **View in logs** action to jump straight to the full delivery detail in your [message logs](/docs/platform/analytics/message-logs).

## Duplicating a broadcast

To send something similar again, open a past broadcast and click **Duplicate broadcast**. Courier copies its content and setup into a new draft that you can adjust and send, which makes recurring announcements quick to repeat.
