What is DMARC?

DMARC (Domain-based Message Authentication, Reporting and Conformance) helps protect your domain from email spoofing and phishing attacks.

When correctly configured alongside SPF and DKIM, DMARC helps email providers verify that messages sent from your domain are legitimate and reduces the likelihood of emails being rejected or sent to spam folders.

SPF, DKIM & DMARC Troubleshooting

Incorrect DNS or email authentication settings can cause problems such as:

• Emails going to spam
• Rejected messages
• Failed email delivery
