Setting up DMARC for a domain used in mobile marketing campaigns involves several steps:
Assess Current Email Authentication Setup: Begin by assessing the current email authentication mechanisms implemented for the domain, such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). Ensure that these mechanisms are correctly configured and operational.
Publish a DMARC Record: Create a DMARC TXT record in the DNS (Domain Name System) settings for the domain. This record includes information about the DMARC policy, such as the desired action to be taken when an email fails authentication (e.g., none, quarantine, or reject).
Monitor and Analyze Email Traffic: Once the DMARC record is published, begin monitoring email traffic using DMARC reporting tools provided by email service providers or third-party DMARC monitoring services. These tools generate reports that provide insights into email authentication results, including information about legitimate and unauthorized use of the domain.
Gradually Enforce DMARC Policies: Initially, set the DMARC policy action to "none" (p=none) to monitor email traffic without impacting email deliverability. Analyze the DMARC reports to identify sources of unauthorized email activity and ensure that legitimate email sources are correctly authenticated using SPF and DKIM.
Adjust DMARC Policy Settings: Based on the insights gained from DMARC reports, gradually adjust the DMARC policy settings to enforce stricter actions, such as quarantining or rejecting emails that fail authentication. Consider implementing a phased approach to policy enforcement to minimize the risk of disrupting legitimate email traffic.
Regularly Review and Update DMARC Configuration: Continuously monitor DMARC reports and review the effectiveness of the DMARC policy settings. Regularly update the DMARC configuration as needed to adapt to changes in email traffic patterns and evolving security threats.
Communicate DMARC Implementation: Inform stakeholders, including internal teams and external partners, about the implementation of DMARC for the domain used in mobile marketing campaigns. Ensure that relevant parties are aware of the potential impact on email delivery and the steps they can take to comply with DMARC policies.
