I don’t have personal experiences, but I can provide the following DMARC best practices for organizations using email:
1. Implement DMARC properly: Ensure that DMARC records are correctly configured in your DNS and that the policy is set correctly. A policy of ‘none’ is a good start, as it allows you to monitor the impact of implementing DMARC without actually taking any action.
1. Use SPF and DKIM: SPF and DKIM are two other important email authentication protocols that work alongside DMARC to protect your brand from email spoofing. Ensure that SPF and DKIM records are properly configured and correctly aligned so that they work together with DMARC.
1. Set up email reporting: DMARC provides detailed email reports that allow you to monitor email usage and detect any abnormalities. Set up email reporting to make the most of DMARC data and detect any issues early.
1. Follow DMARC data: Monitor DMARC reports regularly to ensure that policies are being enforced correctly and that email activity is legitimate. DMARC data can also provide insights into who is using your brand and how they are using it.
1. Implement gradually: Implement DMARC gradually across your email channels and domains. This will allow you to monitor the impact and detect any issues before they become a problem.
1. Educate employees: Ensure that employees are aware of the importance of DMARC and email authentication. Provide training to ensure that they understand the risks of email spoofing and the importance of verifying email senders.
