What is DMARC? How is DMARC Deployment done?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a type of email protocol that uses SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Emails). It controls the situation when email fails authentication tests. It is published on the side of the domain.

It needs some preliminary work before you implement DMARC, including, of course, corporate consent, because it covers the entire company.

  1. Identify all your company domains

    The first phase of your DMARC implementation project is to analyze all your organization-owned domains. Identify all domains that sent an email, active and parked (inactive) domains, on behalf of your client. Don’t ignore your own inactive domain.

  2. Attach all domains known to your dashboard

    The next step is to include in your account all the domains that you found in the previous step. Also, don’t forget to add your inactive domains.

  3. Create DMARC record

    The next step is to generate your domains with a DMARC record. Your DMARC record is the core of a DMARC implementation. The DMARC record is a text that is connected to the parent domain.

  4. Publish the DMARC record created in your DNS

    The next step is to publish in your DNS the DMARC record generated in the previous step. It is essential to publish DMARC records in the DNS. You can do this yourself or ask your DNS provider if the appropriate DMARC record can be put.

  5. Analyze the data of your DMARC

    Analyzing data is the most important part. Once DMARC is implemented the data needs to be viewed before applying policy. It may take up to some time to see your account’s DMARC details. You will gain insight into your email channel(s) with these reports, using this data to better understand your mail sources.
