In order to implement DMARC you need a valid DMARC record. At DMARC Analyzer we provide a free to use tool called DMARC Record Check to display your DMARC record, test it and verify whether it’s valid. DMARC Record Check is free and easy to use. To perform a DMARC check you will only need to provide your domain name. The DMARC Record Check will then parse your DMARC record and displays the DMARC record along with additional information.
Use DMARC Record Check to test and lookup your DMARC record. You can evaluate each possible option and the ones you’ve implemented. DMARC Record Check will also verify and test if you are using external domains.
Use the DMARC record checker to validate your DMARC record(s)

A DMARC test performed with DMARC Record Check will test and declare the following tags.
|v||DMARC protocol version.|
|p||Apply this policy to apply to email that fails the DMARC check. Can be “none”, “quarantine”, or “reject”. “none” is used to collect the DMARC report and gain insight into the current email flows and their status.|
|rua||A list of URIs for ISPs to send XML feedback to. NOTE: this is not a list of email addresses. DMARC requires a list of URIs of the form “mailto:[email protected]”.|
|ruf||A list of URIs for ISPs to send forensic reports to. NOTE: this is not a list of email addresses. DMARC requires a list of URIs of the form “mailto:[email protected]”.|
|rf||The reporting format for forensic reports. This can be either “afrf” or “iodef”.|
|pct||The percentage tag instructs ISPs to only apply the DMARC policy to a percentage of failing email’s. “pct=50” will tell receivers to only apply the “p=” policy 50% of the time against emails that fail the DMARC check. NOTE: this will not work for the “none” policy, but only for “quarantine” or “reject” policies.|
|adkim||Specifies the “Alignment Mode” for DKIM signatures, this can be either “r” (Relaxed) or “s” (Strict). In Relaxed mode also authenticated DKIM signing domains (d=) that share an Organizational Domain with an emails ‘From’ domain will pass the DMARC check. In Strict mode an exact match is required.|
|aspf||Specifies the “Alignment Mode” for SPF, this can be either “r” (Relaxed) or “s” (Strict). In Relaxed mode also authenticated SPF domains that share an Organizational Domain with an emails ‘From’ domain will pass the DMARC check. In Strict mode an exact match is required.|
|sp||This policy should be applied to email from a sub-domain of this domain that fails the DMARC check. Using this tag domain owners can publish a “wildcard” policy for all subdomains.|
|fo||Forensic options. Allowed values: “0” to generate reports if both DKIM and SPF fail, “1” to generate reports if either DKIM or SPF fails to produce a DMARC pass result, “d” to generate report if DKIM has failed or “s” if SPF failed.|
|ri||The reporting interval for how often you’d like to receive aggregate XML reports. This is a preference and ISPs could (and most likely will) send the report at different intervals (normally this will be daily).|
