## Request

4 fields.

| Field       | In    | Type    | Required | Description                                                                                                                          |

| `channel`   | query | string  | —        | Channel is the surface opted out of: email, sms, social, meta, google or tiktok.                                                     |
| `address`   | query | string  | —        | Address is the recipient, normalized (lower-cased, trimmed) so an opt-out cannot be slipped past on a case or whitespace difference. |
| `reason`    | query | string  | —        | Reason is a free-text note, capped at 1024 bytes.                                                                                    |

## Response

| Status    | Body            | Meaning    |
| --------- | --------------- | ---------- |
| `204`     | —               | no content |
| `default` | problem-details | refused    |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo marketing suppressions clear
```

**SDK**

**.ts**

```ts
import { Configuration, MarketingApi } from 'hanzoai';

const api = new MarketingApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.deleteMarketingSuppressions();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import MarketingApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = MarketingApi(client).delete_marketing_suppressions()
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.MarketingAPI.DeleteMarketingSuppressions(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, marketing_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = marketing_api::delete_marketing_suppressions(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.MarketingApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new MarketingApi(client).deleteMarketingSuppressions();
```

**HTTP**

```bash
curl -X DELETE https://api.hanzo.ai/v1/marketing/suppressions \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **marketing** through the `marketing` tool, which names its 35 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_marketing_audiences"
         }
       }
     }'
```
