Why It Matters
Your Email Domain Is One of Your Business's Most Valuable Assets
Every day, cybercriminals impersonate legitimate businesses by sending fraudulent emails that appear to come from trusted domains. These attacks can lead to financial loss, damaged customer relationships, and long-term harm to your brand's reputation.
Without the proper email authentication controls in place, your domain can be used to send spoofed emails that your customers, suppliers, and employees believe are genuine.
Many organisations assume Microsoft 365 automatically protects them against these attacks. While Microsoft 365 provides powerful security capabilities, protecting your email domain also requires the correct implementation of SPF, DKIM, and DMARC. Unfortunately, configuring these technologies incorrectly can cause legitimate emails to fail authentication or be rejected by recipient mail servers.
Professional DMARC implementation helps protect your domain while ensuring legitimate business emails continue reaching your customers' inboxes.
Why Businesses Are Implementing DMARC
- Prevent domain spoofing and phishing attacks
- Protect customers from fraudulent emails
- Improve email deliverability
- Strengthen Microsoft 365 email security
- Meet email authentication best practices
- Gain visibility into who is sending email using your domain
- Reduce the risk of Business Email Compromise (BEC)
Implementing DMARC isn't simply about protecting your email system — it's about protecting your business reputation and maintaining customer trust.
Our Approach
Managed DMARC Services That Protect Your Business
Implementing DMARC is more than adding a DNS record. Successful DMARC setup requires careful planning, correct SPF and DKIM configuration, ongoing monitoring, and continuous optimisation to ensure your business remains protected while legitimate emails continue reaching their intended recipients.
House of I.T provides Managed DMARC Services that combine technical implementation with ongoing management, helping businesses across the Philippines strengthen their email security without the complexity of managing DMARC internally.
Rather than simply configuring your domain and leaving you to interpret reports, we become your long-term DMARC provider, monitoring authentication activity, identifying potential threats, and recommending improvements as your business evolves.
Whether you're implementing DMARC for the first time or improving an existing configuration, our specialists help ensure your Microsoft 365 environment follows email authentication best practices while reducing the risk of spoofing and phishing attacks.

Frequently Asked Questions
Frequently Asked Questions About Managed DMARC Services
What is DMARC, and why does my business need it?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication standard that helps protect your domain from spoofing, phishing, and email impersonation. It works alongside SPF and DKIM to verify that emails sent from your domain are legitimate, helping protect your brand reputation and improve email deliverability.
Does Microsoft 365 include DMARC?
Microsoft 365 supports DMARC, but it doesn't automatically configure it for your domain. Proper implementation requires configuring SPF, DKIM, DNS records, and DMARC policies correctly. House of I.T provides complete implementation and ongoing management to help ensure your email authentication is configured properly.
Will implementing DMARC interrupt my email service?
When implemented correctly, DMARC should not interrupt legitimate email delivery. Our engineers carefully assess your environment, validate existing email services, and gradually apply DMARC policies to minimise risk while maintaining business continuity.
How long does DMARC implementation take?
Most implementations can be completed within a few business days, depending on the complexity of your email environment, the number of domains, and the email platforms your business uses.
Can you manage DMARC after implementation?
Yes. Our Managed DMARC Services include ongoing monitoring, reporting, policy optimisation, and support to help ensure your email authentication remains effective as your business evolves.
Can you implement DMARC for multiple domains?
Yes. We can configure and manage DMARC across multiple business domains, subsidiaries, and brands while providing centralised reporting and ongoing management.
Do I need SPF and DKIM before implementing DMARC?
Yes. DMARC relies on SPF and DKIM to authenticate outgoing email. As part of our service, we assess your existing configuration and implement or optimise SPF and DKIM where required.
How do I know if my domain already has DMARC configured?
You can use our free DMARC Domain Checker above to instantly identify whether your domain has DMARC, SPF, and DKIM configured and receive insights into your current email authentication status.
