The **campaign delivery score** on the organization dashboard measures campaign-window bounce, complaint, and unsubscribe pressure on a 0–100 scale. It is **not** sender health, inbox placement, or the editor’s content checks.

For organization-level sending health, authentication, and SES infrastructure, use **Settings → Deliverability**. See [Sender Health](/docs/features/sender-health).

## Score calculation

The campaign delivery score starts at **100 points** and is reduced from campaign emails in the selected dashboard date range:

- **Each 1% bounce rate = -5 points** (`bounced / total campaign emails`)
- **Each 1% complaint rate = -10 points** (`complained / total campaign emails`)
- **Each 1% unsubscribe rate = -0.5 points**

The result is clamped between 0 and 100.

This formula is independent of the 30-day **sender health** trust score used for verification.

## Understanding the metrics

### Sent

Campaign emails Lumail accepted for sending in the selected window, including messages still in flight.

### Delivered to receiving server

Emails with a delivery outcome from the receiving server. This does **not** guarantee inbox placement — the message can still land in spam.

### Bounced

Emails rejected and not delivered. Lumail tracks permanent and transient bounces. Remove permanent failures from the list.

### Complained

Recipients who used an ISP feedback loop to mark mail as spam. Coverage depends on which providers send complaints.

### Unsubscribed

Deduped unsubscribe events in the same window.

## Score interpretation

| Score range | Status | Action |
| --- | --- | --- |
| 95–100 | Excellent | Keep current list and content practices |
| 80–94 | Good | Watch bounce and complaint trends |
| 60–79 | Needs attention | Clean invalid addresses and review complaint sources |
| 0–59 | Critical | Pause and investigate before more volume |
