Opus Technology is proud to announce a new partnership with Sendmarc, a global leader in domain security and email authentication. This collaboration enables us to bring industry-leading DMARC enforcement and anti-spoofing protection to our clients as part of our expanding cyber security portfolio.
Why did Opus become a Sendmarc partner?
At Opus, we work with organisations across the UK to secure and modernise their infrastructure through a combination of telecoms, managed IT, and cyber solutions. Email remains one of the most exploited attack vectors, and as regulations tighten and cyber threats evolve, organisations need smarter, automated protection that fits seamlessly into their existing environments. That’s why we’ve chosen to partner with Sendmarc.
Sendmarc’s automated DMARC platform enhances domain protection by helping businesses block phishing, impersonation, and spoofing attacks — some of the most common causes of financial loss and reputational damage. The solution also supports compliance with SPF, DKIM, DMARC, and emerging standards such as BIMI, MTA-STS, and TLS-RPT.
This partnership reinforces our commitment to delivering future-ready cybersecurity solutions. With Sendmarc’s intelligent platform now part of our service offering, Opus clients can gain peace of mind knowing their email ecosystems are secured against growing digital threats, while also meeting the requirements set by email providers like Google, Yahoo, and Microsoft, who now mandate authentication for bulk email senders.
“We focus on empowering our clients through technology and security. Sendmarc adds a crucial layer of protection to our services, enabling us to help customers combat email impersonation and improve domain security with ease.”
The Benefits of Sendmarc
Sendmarc is more than just a DMARC platform, it’s a fully automated system designed to take the complexity out of email security. As a managed service through Opus, clients can expect:
Complete Domain Visibility and Monitoring
Sendmarc continuously monitors email traffic, providing a clear picture of who is sending emails on behalf of your domain. This helps quickly identify and block unauthorised senders before they can do harm.
Protection from Spoofing and Phishing
The platform enforces DMARC, SPF, and DKIM protocols to ensure that only verified emails reach inboxes, stopping cybercriminals from using your brand to trick customers or employees.
Improved Email Deliverability
By implementing proper authentication, businesses often see an improvement in email delivery rates. Legitimate emails are less likely to land in spam folders, improving communication with customers and partners.
Regulatory and Industry Compliance
With email providers tightening their rules on authentication, Sendmarc ensures that organisations meet the latest requirements from Google, Yahoo, and Microsoft, as well as upcoming global standards.
Simplified Management and Reporting
Sendmarc’s dashboards and automated reports provide easy-to-understand insights into email activity and domain security status. Through Opus’ managed IT service, we take care of setup, monitoring, and adjustments, so our clients can focus on their business.
Support for Advanced Protocols
Beyond DMARC, Sendmarc supports BIMI (Brand Indicators for Message Identification), MTA-STS (Mail Transfer Agent – Strict Transport Security), and TLS-RPT (Transport Layer Security Reporting), ensuring a robust and trusted email infrastructure.
