DMARC provides three core benefits:
- DMARC protects your business’s domain by blocking fraudulent emails and safeguarding customers, suppliers, employees, and external recipients
- DMARC improves email delivery and inbox placement for authenticated email sources like your company’s CRM, ERP, marketing tools, and primary email services
- DMARC provides visibility into all emails sent on behalf of your organization’s domain, both legitimate and malicious
If your business sets up a DMARC record in its DNS, it can monitor services sending email from its domain and enforce policies that prevent spoofing and impersonation.
Sendmarc’s DMARC management platform provides everything your company needs to manage DMARC, SPF, DKIM, Mail Transfer Agent Strict Transport Security (MTA-STS), Transport Layer Security Reporting (TLS-RPT), and Brand Indicators for Message Identification (BIMI), supported by Sendmarc’s award-winning DMARC implementation services.
Why is DMARC important for email security?
Email communication wasn’t originally created with identity verification in mind. This means cybercriminals can send emails from your organization’s domain and target customers, employees, or suppliers.
Email impersonation and spoofing attacks often lead to:
- Invoice fraud and deposit scams
- Man-in-the-Middle (MitM) attacks
- Phishing attempts
Traditional email security tools primarily protect internal users. This leaves external recipients, such as customers and suppliers, vulnerable to spoofed emails.
DMARC offers the following benefits:
- Stops domain impersonation by blocking spoofed emails from your business’s domain before they reach inboxes
- Improves inbox placement for legitimate and authenticated emails
- Provides detailed reports on all services sending email on behalf of your company’s domain, both legitimate and malicious
DMARC uses SPF and DKIM results to check if a message should be trusted.
- An email is received
- The receiving server verifies whether the message passes SPF or DKIM checks and if those align with the ‘From’ domain
- Based on the DMARC policy (p=none, p=quarantine, or p=reject), the server decides how to handle unauthenticated messages
- Your organization receives DMARC reports to track activity and adjust enforcement
Benefits of DMARC
Implementing DMARC can significantly improve the security, deliverability, and visibility of your organization’s email.
Key benefits include:
- Prevents spoofing and phishing attacks by blocking unauthorized senders from using your business’s domain
- Improves inbox placement and strengthens the sender reputation of your company’s legitimate email services
- Builds customer trust by verifying your organization’s email identity and ensuring authenticity
- Provides full visibility into all sources that are sending emails on behalf of your business’s domain, both legitimate and malicious
- Reduces the risk of your company’s emails being blacklisted or flagged as Spam
