- Domain-based Message Authentication, Reporting and Conformance
The DMARC specification allows senders and recipients to exchange email authentication to guard against online phishing and other bad practices in the messaging industry.
DMARC.org is a group that was created by 15 email services providers, financial firms and message security companies in 2012. Members of the group include Google, Microsoft, Return Path and Yahoo. DMARC.org aims to create standards or email marketing best practices to combat the threats posed by phishing, spam and other abuses of email. DMARC adoption is important for marketers, as large ISPs and inbox providers such as Gmail and Yahoo are key gatekeepers to large segments of customers — if a business’ email is not DMARC compliant, its email deliverability could be adversely affected.
