Challenges and Considerations in DMARC Implementation

While DMARC offers substantial benefits, certain challenges need to be navigated for its successful implementation:

1. Continuous Monitoring and Adjustment:

  • Regularly reviewing DMARC reports to adapt to new email trends and potential threats.
  • Updating DMARC policies as needed to maintain a high level of email security.

2. Vendor Management and Compliance:

  • Ensuring all third-party vendors who send emails on behalf of the business comply with the DMARC policy.
  • Regular communication and coordination with vendors to maintain alignment with DMARC settings.

3. Internal Coordination:

  • Keeping open lines of communication between IT staff and other departments to ensure any new email services or changes are DMARC compliant.
  • Training staff to understand the importance and role of DMARC in the organization’s email security strategy.


Implementing DMARC is important for businesses seeking to strengthen their email security and maintain a strong relationship of trust with customers. While challenges exist, such as the need for continual monitoring, vendor management, and internal communications exist, they are manageable and well worth the effort considering the protection and peace of mind DMARC provides.
