Test your domain's
DMARC Status
Use our DMARC testing tool to check the health status of your domain. The tool will show you if your domain is protected against phishing, spoofing and abuse by analyzing SPF, DKIM and DMARC for the domain. Get a quick insight into whether you need to take any action or if the domain name is protected.
Enter the domain name (eg dmarc.nu) that you want to test in the field above.
What is DMARC?
DMARC is an email authentication system that protects your organization's domain name from phishing, spoofing and other types of cyber attacks. DMARC builds on the email verification technologies SPF and DKIM and by implementing a DMARC policy for your domain you gain insight into how the domain name is used. By a correct implementation of a DMARC security policy you will help the recipient to understand which emails to trust and witch to reject.
SPF
The Sender Policy Framework (SPF) allows you to specify in your domain name settings (DNS) which email servers that can send email on your behalf. Receiving email servers use SPF to verify that incoming messages that appear to come from your domain have been sent from servers that you have authorized. The SPF specification has a limit on the number of maximum 10 DNS lookups to be considered as valid.
DKIM
DKIM (Domain Keys Identified Mail) is an email authentication technology that helps the recipient verify that an email has been sent and authorized by the domain owner. The e-mail is sent signed with a Private key. The recieving system validates the email by looking up the DKIM signature using the Public Key that is published on the DNS in order verify that the message has not changed since it was sent.
DMARC
DMARC (Domain-based Message Authentication, Reporting and Conformance) provides insight into your email flow, which sources that send email on behalf of you, whether they are sent technically correct, as well your exposure to spoofing, phishing and other types of email related attacks. The DMARC policy for the domain informs the recipient how to handle emails that fail the DMARC check.
DMARC Dashboards - Health Status in Sweden
We have created dashboards that show the DMARC health status in Sweden. Detailed information for each category is obtained by clicking on the category name. The checks are run on a daily basis and show whether the domain names being tested are fully protected or not. The DMARC check also looks for tehnical issues that affect email delivery for the tested domain names.

Enhanced security with - VMC + BIMI
If a DMARC policy with the right level of protection has been implemented for a domain name there are additional possibilities to enahnce the email security and brand visibility. By implementing DMARC domain owners are eligble to implement the new standards for email communication, Verified Mark Certificate (VMC) and Brand Indicators for Message Identification (BIMI), for ther domains. When implementing VMC and BIMI the recipient sees your logo in ther email client and can fully rely on that the email actually comes from your organization. For more information about DMARC, VMC, BIMI and how we can help you with this visit DMARC.SE.
