DMARC FAQs (Frequently Asked Questions)

What is DMARC?

DMARC, short for Domain-based Message Authentication, Reporting & Conformance, is an email authentication protocol to check if an email message really originates from where it claims to have, based on SPF and DKIM. In addition to email authentication, it also adds reporting capabilities, so that domain owners can examine email delivery statistics on their domains.

Why use DMARC? Does DMARC prevent spoofing?

Yes, it does. When DMARC is implemented in the reject mode, it prevents all spoofing emails from ever reaching the inbox.

Who is using DMARC? Give me some companies using DMARC?

Most (if not all) email service providers support DMARC, which is the de facto email authentication in the industry. Not supporting DMARC would be an anomaly.

Companies that support DMARC include: Google, Microsoft, Amazon, LinkedIn, and many more.

Is DMARC for small and medium-sized businesses (SMB) or large enterprises?

DMARC is necessary for any business who cares about their email deliverability, security and brand reputation, be it big or small.

Not all all. You can generate a DMARC record using our free online DMARC record generator and publish it in the DNS in 5 minutes, and start seeing aggregate reports dripping in after a day or two. That will give you some insight into the email streams on your domain, then you can move on to implement the quaratine/reject modes of DMARC.

Should I use DMARC?
