Step Function to Send Email on Error/Success

If you want to get a notification on the Step Function execution failure (or even successful runs), you can setup a CloudWatch rule to monitor the execution status and then set the target as SNS topic to send an email when the rule is triggered.

Hi, Good Question

You could probably refer to https://github.com/aws-samples/aws-step-functions-notification-workflow for Step Function to Send Email on Error/Success using Lambda (https://github.com/aws-samples/aws-step-functions-notification-workflow/blob/master/src/lambda/SendEmailNotification.zip)

You need to follow the structure of SES API V2 https://docs.aws.amazon.com/ses/latest/APIReference-V2/API_SendEmail.html

In your case you are sending a Simple email:

{
    "Content": {
        "Simple": {
            "Body": {
                "Text": {
                    "Data": "ERROR"
                }
            },
            "Subject": {
                "Data": "ERROR"
            }
        }
    },
    "Source": "source@me.com",
    "Destination": {
        "ToAddresses": [
            "notify@me.com"
        ]
    }
}

I ran into this today. The SES API V2 endpoint for state machines seems broken; I couldn't add Destination, which makes it pointless. I messed around with the GUI builder and could generate something that worked from a step using ses v1.

  "SendEmail": {
    "Type": "Task",
    "Resource": "arn:aws:states:::aws-sdk:ses:sendEmail",
    "Next": "Failure",
    "Parameters": {
      "Source": "from-email",
      "Message": {
        "Body": {
          "Text": {
            "Data": "text"
          }
        },
        "Subject": {
          "Data": "subject"
        }
      },
      "Destination": {
        "ToAddresses": []
      }
    }
  }
