Domain-based Message Authentication, Reporting, and Conformance (DMARC) helps mail server administrators to prevent hackers and other attackers. It provides extra protection of email accounts from spam, spoofing, and phishing.
DMARC is the key to improving Email Deliverability! By some measures, 80% of mailboxes worldwide are protected by DMARC. DMARC dramatically improves on SPF and DKIM by letting you:
- Monitor, detect and fix real world problems with your SPF and DKIM configuration
- See the email volumes you’re delivering to inboxes
- Identify threat emails pretending to come your domain. (Spoofing)
- Control the delivery of your email and defend against spoofing attacks.
How do I set it up?
Before we begin, here’s a high-level overview of how to add DMARC to your DNS.
- Add your DMARC record into your DNS
- Select the TXT record type
- Add the host value (see details below)
- Add the value information (see details below)
