Enhancing Email Security with Mark Certificates

In a bustling landscape of digital communication, your existing and potential customers are receiving emails from a variety of senders at an alarming rate. With the additional constant threat of phishing attacks and spam, the chances are that some of your emails are being deleted, ignored, or blocked by servers. If you are not sure where an email originated from, you delete it – and this is what customers may be doing to your legitimate emails. You need to stand out from the crowd and ensure customers that your emails are legitimate and trustworthy. But how?

To combat the challenges of congested inboxes, GlobalSign has introduced an effective new solution to change your organization’s approach to email security: Mark Certificates.

What are Mark Certificates?

Mark Certificates are digital certificates that provide authentication and verification for email senders. They serve as a seal of trust, confirming that the emails you receive are indeed from legitimate sources and have not been tampered with during transit.

The Benefits of Mark Certificates:

  • Enhanced Trust: Mark Certificates instill confidence in recipients by verifying the authenticity of email senders, reducing the risk of falling victim to phishing attacks
  • Improved Deliverability: Emails bearing Mark Certificates are more likely to reach recipients' inboxes instead of being filtered out as spam, ensuring better deliverability rates
  • Brand Protection: Mark Certificates safeguard your brand reputation by demonstrating a commitment to security and authenticity in email communications
  • Compliance Assurance: Mark Certificates help organizations meet security standards and regulatory requirements, ensuring compliance with industry regulations such as Domain-Based Message Authentication Reporting and Conformance (DMARC)
  • Positive User Experience: By fostering trust and security in email interactions, Mark Certificates contribute to a positive user experience, enhancing overall satisfaction and engagement

How Do Mark Certificates Work?

Mark Certificates work by providing sender authentication and verification through a different email authentication protocol. Once an organization’s identity is verified, a Mark Certificate is issued for their domain and trademark logo, serving as proof of authenticity. Emails sent by verified senders are signed using cryptographic methods. Recipients' email clients then verify the sender's identity against the Mark Certificate, displaying their logo as a visual indicator to signify that the email is from a trusted source.
