During that interval, if you continue to send SMS messages, you will incur costs that exceed your limit.</p></important><p><code>DeliveryStatusIAMRole</code> – The ARN of the IAM role that allows Amazon SNS to write logs about SMS deliveries in CloudWatch Logs. For each SMS message that you send, Amazon SNS writes a log that includes the message price, the success or failure status, the reason for failure (if the message failed), the message dwell time, and other information.</p><p><code>DeliveryStatusSuccessSamplingRate</code> – The percentage of successful SMS deliveries for which Amazon SNS will write logs in CloudWatch Logs.

To write logs for 10% of your successful deliveries, set it to <code>10</code>.</p><p><code>DefaultSenderID</code> – A string, such as your business brand, that is displayed as the sender on the receiving device. Support for sender IDs varies by country. The sender ID can be 1 - 11 alphanumeric characters, and it must contain at least one letter.</p><p><code>DefaultSMSType</code> – The type of SMS message that you will send by default. You can assign the following values:</p><ul><li><p><code>Promotional</code> – Noncritical messages, such as marketing messages. Amazon SNS optimizes the message delivery to incur the lowest cost.</p></li><li><p><code>Transactional</code> – (Default) Critical messages that support customer transactions, such as one-time passcodes for multi-factor authentication. Amazon SNS optimizes the message delivery to achieve the highest reliability.</p></li></ul><p><code>UsageReportS3Bucket</code> – The name of the Amazon S3 bucket to receive daily SMS usage reports from Amazon SNS. Each day, Amazon SNS will deliver a usage report as a CSV file to the bucket. The report includes the following information for each SMS message that was successfully delivered by your account:</p><ul><li><p>Time that the message was published (in UTC)</p></li><li><p>Message ID</p></li><li><p>Destination phone number</p></li><li><p>Message type</p></li><li><p>Delivery status</p></li><li><p>Message price (in USD)</p></li><li><p>Part number (a message is split into multiple parts if it is too long for a single message)</p></li><li><p>Total number of parts</p></li></ul><p>To receive the report, the bucket must have a policy that allows the Amazon SNS service principle to perform the <code>s3:PutObject</code> and <code>s3:GetBucketLocation</code> actions.</p><p>For an example bucket policy and usage report, see <a href="http://docs.aws.amazon.com/sns/latest/dg/sms_stats.html">Viewing Statistics About SMS Message Delivery</a> in the <i>Amazon SNS Developer Guide</i>.</p>
