Stop criminals sending emails from your domain.
Without DMARC enforcement, anyone can send email pretending to be you. 83% of UK organisations have no enforcement in place. IP Four configures DMARC, SPF, and DKIM correctly so your domain cannot be spoofed.
Complete email authentication done correctly.
DMARC, SPF, and DKIM work together. Getting one wrong breaks the others. We configure all three correctly and maintain them as your business and sending services change.
DMARC Policy Implementation
Full DMARC deployment from monitoring through quarantine to reject policy. Configured correctly so legitimate email is never blocked while spoofed email is stopped completely.
SPF Record Configuration
Sender Policy Framework records configured to authorise every legitimate sending source for your domain. Third-party senders like CRMs, marketing platforms, and helpdesks included.
DKIM Setup and Alignment
DomainKeys Identified Mail configured for your mail platform and all third-party sending services. Cryptographic signatures verify your emails are genuine and unaltered in transit.
DMARC Reporting and Analysis
Aggregate and forensic DMARC reports collected and analysed. Human-readable dashboards show who is sending email on behalf of your domain and whether it is passing authentication.
Brand Protection
Proper DMARC enforcement stops criminals using your domain to attack your clients and suppliers. Correct authentication also improves legitimate email deliverability to major providers.
Ongoing Monitoring and Enforcement
DMARC records monitored continuously for new sending sources and policy failures. SPF and DKIM updated when you add new services. Monthly reporting on authentication health.
From audit to full enforcement.
