title: Iot Rule is sending the messages to SNS but SNS is unable to send notifications
body: <p>I am writing a rule in IoT core which sends messages to SNS and SQS. In SQS the data is being stored in queue successfully. But SNS is not sending an email. I have followed the same AWS documentation but of no use. I am tried in different accounts and also different email addresses. Can anyone solve this issue</p>
