Introduction to Amazon SES Internal Review Period

Amazon Simple Email Service (SES) is a robust, scalable, and cost-effective email-sending service designed for marketers and application developers. To maintain the quality and reputation of its email ecosystem, Amazon SES employs an internal review process for AWS accounts that exhibit problematic email-sending behavior. This comprehensive guide delves into the intricacies of the SES internal review period, outlining the triggers, processes, best practices, and steps to resolve issues effectively.

Triggers for Internal Review

Amazon SES continuously monitors various metrics to ensure compliance with its policies and to safeguard against email abuse. The internal review period is typically initiated when specific thresholds related to email sending performance are exceeded. Understanding these triggers is crucial for maintaining uninterrupted email delivery capabilities.

1. High Bounce Rates

A bounce rate above 10% is a significant indicator of issues with email deliverability. High bounce rates suggest that a substantial portion of sent emails are not reaching their intended recipients, which can harm the sender's reputation. Bounces are classified into two categories:

• Hard Bounces: Permanent delivery failures due to invalid email addresses.
• Soft Bounces: Temporary issues such as a full inbox or server problems.

2. Elevated Complaint Rates

A complaint rate exceeding 0.5% can trigger an internal review. Complaints occur when recipients mark emails as spam or unsolicited, indicating dissatisfaction with the content or frequency of emails. High complaint rates adversely affect the sender's reputation and can lead to stricter enforcement actions.

3. Repeated Issues

Accounts that have previously been placed under review for similar issues may face escalated scrutiny. Recurring problems indicate persistent non-compliance with SES policies, increasing the likelihood of account suspension if not addressed adequately.

The Internal Review Process

Once triggered, the internal review period involves several steps aimed at identifying and resolving the underlying issues affecting email performance.

Notification of Review

Amazon SES notifies account owners via the primary email address associated with the AWS account. This notification outlines the reasons for the review and provides initial guidance on addressing the identified issues.

Monitoring During the Review Period

During the review, Amazon SES continues to monitor email-sending behavior closely. The reputation dashboard within the SES console provides real-time updates on metrics such as bounce and complaint rates. Possible account statuses during this period include:

Status	Description
Under Review	Your account is being monitored for compliance with SES policies.
Pending End of Review Decision	A manual review is underway to determine the appropriate action.
Sending Paused	Your account's ability to send emails has been temporarily paused due to unresolved issues.

Actions During the Review Period

While under review, users are expected to take proactive measures to rectify the issues. Although sending emails is permitted during this period, the emphasis is on addressing the root causes to restore normal operations.

Steps to Resolve Issues

1. Stop or Reduce Email Sending: Temporarily halt or scale back email campaigns to minimize further complaints and bounces.

2. Investigate the Cause: Analyze email metrics to identify patterns or specific issues contributing to high bounce or complaint rates.

3. Implement Corrective Measures: Update mailing lists to remove invalid addresses, improve email content quality, and ensure proper email authentication.

4. Communicate with AWS Support: Respond to the case opened by Amazon SES in the Support Center, detailing the changes made and how they prevent future issues.

Requesting a Review

If you believe the internal review was initiated in error or have successfully addressed the issues, you can request a formal review. This involves:

• Submitting a detailed response via the AWS Support Center.
• Providing evidence of corrective actions taken.
• Explaining measures implemented to prevent recurrence.

Post-Review Outcomes

Upon conclusion of the review period, Amazon SES evaluates the effectiveness of the corrective measures implemented. The possible outcomes include:

Outcome	Description
Reinstatement	If metrics improve and issues are resolved, normal email-sending privileges are restored.
Extended Review or Suspension	If problems persist, the account may face extended review periods or a complete suspension of email-sending capabilities.

Impact on Other AWS Services

While under SES review, other AWS services remain accessible. However, certain actions related to outbound communication services may be restricted:

• Requests for service quota increases for communication services may be denied until the SES review is resolved.
• Access to other AWS resources is not directly impacted by the SES review, allowing continued use of unrelated services.

Best Practices to Prevent Internal Reviews

Proactively maintaining good email-sending practices can significantly reduce the likelihood of triggering an internal review. Implementing the following strategies ensures a healthy sender reputation and optimal email deliverability:

1. Maintain a Clean Email List

Regularly updating your mailing lists to remove invalid, inactive, or unengaged email addresses minimizes bounce rates and reduces the chances of emails being marked as spam.

2. Engage with Subscribers

Delivering relevant and valuable content enhances subscriber engagement, lowering complaint rates. Personalized and targeted email campaigns are more likely to resonate with recipients.

3. Monitor Sending Metrics

Utilize the SES reputation dashboard and other monitoring tools to keep a vigilant eye on key metrics like bounce and complaint rates. Early detection of anomalies enables timely intervention.

4. Implement Email Authentication

Employing authentication protocols such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) enhances email legitimacy and improves deliverability rates.

5. Adhere to SES Sending Limits

Understanding and adhering to SES sending limits, including the maximum number of emails sent per second and per 24-hour period, prevents overstepping thresholds that could trigger reviews.

Technical Measures and Configurations

Beyond best practices, implementing specific technical configurations can bolster your email-sending infrastructure, ensuring compliance with SES policies.

Email Authentication Protocols

Properly setting up SPF, DKIM, and DMARC records not only improves deliverability but also protects against email spoofing and phishing attacks.

    
# SPF Record Example
v=spf1 include:amazonses.com -all

# DKIM Record Example
default._domainkey.example.com IN CNAME default.dkim.amazonses.com

# DMARC Record Example
_dmarc.example.com IN TXT "v=DMARC1; p=none; rua=mailto:dmarc-reports@example.com"
    
  

Using Dedicated IP Addresses

For high-volume senders, leveraging dedicated IP addresses can provide greater control over email reputation. Segregating email streams based on sending purposes reduces the impact of changes in one stream on others.

Implementing Feedback Loops

Subscribing to feedback loops allows you to receive notifications when recipients mark your emails as spam. This immediate feedback facilitates swift action to address and mitigate complaint rates.

Steps to Resolve an Internal Review

If your AWS account is placed under an SES internal review, following a structured approach to resolve the issues is vital for restoring normal email-sending capabilities.

1. Assess the Notification

Carefully review the email notification from Amazon SES to understand the specific issues that triggered the review. Pay attention to referenced metrics and any recommended actions.

2. Analyze Email Metrics

Utilize the SES reputation dashboard to dissect bounce and complaint rates. Identify patterns such as specific email campaigns, recipient domains, or types of content that may be contributing to the issues.

3. Clean and Validate Email Lists

Implement double opt-in procedures to ensure that only engaged and interested recipients receive emails. Regularly remove invalid or unresponsive email addresses to lower bounce rates.

4. Enhance Email Content Quality

Craft compelling and relevant email content that aligns with recipient expectations. Avoid deceptive subject lines and ensure that calls to action are clear and genuine to reduce complaint rates.

5. Strengthen Email Authentication

Revisit and verify the configuration of SPF, DKIM, and DMARC records to ensure they are correctly implemented, enhancing email legitimacy and deliverability.

6. Engage with AWS Support

Open a support case through the AWS Support Center detailing the steps taken to address the issues. Provide comprehensive information to facilitate a smooth review process.

7. Monitor Post-Resolution Metrics

After implementing corrective measures, continuously monitor email metrics to ensure sustained improvement and compliance with SES policies.
