The Need for Handling Bounces and Complaints​

Managing bounces and complaints efficiently is crucial for maintaining your organization’s email sender reputation. High rates of bounces or complaints can affect your ability to deliver emails and could lead to being blacklisted by email providers.

Step-by-Step Setup​

Step 1: Configuring SES​

First, configure your AWS SES to handle outgoing emails. This involves:

• Setting up verified email identities (email addresses or domains from which you'll send emails).
• Creating configuration sets in SES to specify how emails should be handled and tracked.

Step 2: Integrating SNS for Notifications​

The next step is to set up AWS SNS to receive notifications from SES. This is crucial for real-time alerts on email bounces or complaints:

• Create an SNS topic that SES will publish to when specified events (like bounces or complaints) occur.
• Configure your SES configuration set to send notifications to the created SNS topic.

  "Version": "2008-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "ses.amazonaws.com"
      },
      "Action": "SNS:Publish",
      "Resource": "arn:aws:sns:us-east-1:<account number>:SES-tracking",
      "Condition": {
        "StringEquals": {
          "AWS:SourceAccount": "<account number>"
        },
        "StringLike": {
          "AWS:SourceArn": "arn:aws:ses:*"
        }
      }
    }
  ]
}

Step 3: Using AWS Lambda for Automated Responses​

With SNS in place, integrate AWS Lambda to automate responses based on the notifications:

• Create a Lambda function that will be triggered by notifications from the SNS topic.
• Program the Lambda function to execute actions like logging the incident, updating databases, or even triggering remedial workflows.

            Source=fromEmail,
        )
        print("SES Email Sent.....")
    # Display an error if something goes wrong. 
    except ClientError as e:
        print("SES Email sent! Message ID:"+ e.response['Error']['Message'])
    else:
        print("SES Email sent! Message ID:" + response['MessageId'])

def pp_json(json_thing, sort=True, indents=4):
    if type(json_thing) is str:
        print("json is a str")
        return (json.dumps(json.loads(json_thing), sort_keys=sort, indent=indents).replace(' ', '&nbsp;').replace('\n', '<br>'))
    else:
        return (json.dumps(json_thing, sort_keys=sort, indent=indents).replace(' ', '&nbsp;').replace('\n', '<br>'))
