# Formatting Amazon SNS notifications for storage in Amazon S3 destinations
<a name="firehose-archived-message-format-S3"></a>

The following example shows an Amazon SNS notification sent to an Amazon Simple Storage Service (Amazon S3) bucket, with indentation for readability.

**Note**  
In this example, raw message delivery is disabled for the published message. When raw message delivery is disabled, Amazon SNS adds JSON metadata to the message, including these properties:  
`Type`
`MessageId`
`TopicArn`
`Subject`
`Timestamp`
`UnsubscribeURL`
`MessageAttributes`
For more information about raw delivery, see [Amazon SNS raw message delivery](sns-large-payload-raw-message-delivery.md).

```
{
    "Type": "Notification",
    "MessageId": "719a6bbf-f51b-5320-920f-3385b5e9aa56",
    "TopicArn": "arn:aws:sns:us-east-1:333333333333:my-kinesis-test-topic",     
    "Subject": "My 1st subject",
    "Message": "My 1st body",
    "Timestamp": "2020-11-26T23:48:02.032Z",
    "UnsubscribeURL": "https://sns.us-east-1.amazonaws.com/?Action=Unsubscribe&SubscriptionArn=arn:aws:sns:us-east-1:333333333333:my-kinesis-test-topic:0b410f3c-ee5e-49d8-b59b-3b4aa6d8fcf5",
    "MessageAttributes": {
        "myKey1": {
            "Type": "String",
            "Value": "myValue1"
        },
        "myKey2": {
            "Type": "String",
            "Value": "myValue2"
        }
    }
 }
```

The following example shows three SNS messages sent through an delivery stream to the same Amazon S3 bucket. Buffering is applied, and line breaks separate each message.
