title: CloudWatch alarm action only triggers SNS once
body: <p>I have a CloudWatch alarm created for testing purposes. It checks the number of bytes read on a Kinesis Stream. If less than 1 bytes are received within 1 minute, it triggers alarm and send email via SNS. So, I get email after 1 min, but then after that I don’t get any further email. Is it right the email notification sent only once? In my test data is not flowing all the time. So, ideally, it should send email every minute. Correct?</p>
