We have received many questions about DMARC, but there is one question that stands out the most: “Is DMARC is for us?” The answer is, if you have a public domain, yes DMARC is for you.
The flowchart below should help answer any questions.
NOTE: This flowchart is for email domains. If you have a public domain that is not used for email purposes, it is strongly recommended to implement DMARC at the highest policy level (reject) to prevent unauthorized systems from using that domain in spam/phishing campaigns.
