Monitor and Implement DMARC features and specs

• Increased Email Security
  Implementing DMARC helps protect your domain from being used in phishing and spoofing attacks. By monitoring and enforcing policies, you can ensure that unauthorized senders are not able to forge your domain in fraudulent emails.
• Improved Email Deliverability
  By aligning email authentication standards like SPF and DKIM, DMARC helps improve the deliverability of legitimate emails. ISPs and email providers are more likely to accept your emails into inboxes when they can verify their authenticity.
• Brand Protection
  A DMARC policy can protect your brand’s reputation by preventing malicious parties from sending harmful or fraudulent emails using your domain, thus maintaining trust with your recipients.
• Visibility and Reporting
  DMARC provides detailed reports about who is sending emails on behalf of your domain. This visibility allows you to understand control compliance and security issues, and monitor for unauthorized use of your domain.

Possible disadvantages of Monitor and Implement DMARC

• Implementation Complexity
  Setting up DMARC can be complex, requiring a detailed understanding of email authentication protocols (SPF, DKIM) and DNS settings. This may require IT resources or expertise which some organizations may find challenging to allocate.
• Potential Email Delivery Issues
  If not configured correctly, DMARC can lead to legitimate emails being rejected or marked as spam. Misconfigurations in your SPF and DKIM records can result in enforcement of DMARC policies that block intended email communications.
• Resource Intensive Monitoring
  Effectively monitoring DMARC reports requires time and effort to analyze data and adjust policies accordingly. This process can be resource-intensive, especially for organizations with a large volume of emails.
• Limited Immediate Results
  Achieving the full benefits of DMARC can take time as policies need to be gradually enforced and adjusted, which might delay the immediate perception of improved email security or deliverability.
