Without DMARC, hackers and other malicious users can impersonate messages, making them appear to come from your organization or domain. Turning off DMARC puts your users and your contacts at risk for spam, spoofing, and phishing.
DMARC ensures the destination email systems trust messages sent from your domain. Using DMARC with SPF and DKIM gives organizations more protection against spoofing and phishing email. DMARC helps receiving mail systems decide what to do with messages from your domain that fail SPF or DKIM checks.
DMARC Record CheckerAre email senders and recipients in your business able to tell whether a message comes from the sender in question or not, and what to do if it doesn’t? A genuine DMARC record must be published before DMARC can be implemented. You can see the DMARC record of any particular domain and check to see if the TXT record is genuine and published properly using the Free DMARC Record Checker tool.
DMARC stands for “Domain-based Message Authentication, Reporting & Conformance” and is an open email authentication, policy, and reporting protocol that enables domain owners to combat phishing attacks.
A DMARC record is a DNS TXT record that allows you to control how your email is handled if it fails DMARC authentication.
Why is DMARC needed?
DMARC’s purpose is to protect domains from unauthorized use, commonly known as email spoofing, and help reduce the risk of business email compromise (BEC) attacks, phishing emails, malware, and other cyber threat activities.
