What are DMARC managed services?
Domain-based Message Authentication, Reporting, and Conformance (DMARC) managed services give Managed Services Providers (MSPs) a simple, scalable way to implement email authentication across their client bases. DMARC instructs receiving servers on how to handle suspicious messages.
It works alongside:
Defines which email servers can send messages on behalf of a domain
DomainKeys Identified Mail (DKIM)
Uses cryptographic signatures to verify message integrity
DMARC managed services make it simple to detect, quarantine, or reject fraudulent messages automatically, preventing domain impersonation, protecting customer trust, and improving email deliverability.
Why MSPs should adopt DMARC managed services
Cybercriminals use phishing and spoofing to trick recipients into handing over sensitive data, making email one of the most common attack vectors. Without DMARC, your clients’ domains are vulnerable to:
- Brand impersonation – Attackers exploit trusted brands to trick users
- Reputation damage – Customers lose trust after a phishing incident
- Operational disruption – Breaches lead to downtime, investigations, and costs
By adding managed DMARC services to your portfolio, you:
- Increase customer trust – Prove your commitment to proactive security
- Grow recurring revenue – Offer DMARC as a billable, ongoing service
- Strengthen compliance – Help clients meet security expectations from regulators and email providers
Even when frameworks like GDPR, PCI DSS, and HIPAA don’t explicitly mandate DMARC, strong email authentication aligns with broader security requirements and helps clients meet global standards.
