Use the DMARC record checker tool to validate your DMARC records in seconds

In order to implement DMARC, you need a valid DMARC record. To perform a DMARC record check you simply need to provide your company domain name. The Mimecast DMARC Record Check will then look up your DMARC record from the DNS and return an error message if no record is available or found.

If your domain’s DMARC record is found, the policy will be displayed (see the glossary below for definitions of the tags found in the checker results). The results will also show if there are any problems with your DMARC record and whether you are using external domains.

Protect your brand and stop direct domain spoofing

Attackers are increasingly using your online brand as bait, using direct domain spoofing to trick your customers and partners into sharing credentials, sensitive information and even money, putting your brand and reputation at risk. That’s where Mimecast DMARC Analyzer comes in.
