Trust is the foundation of every successful email interaction. With phishing and brand impersonation at an all-time high, organizations need a way to prove who they are before their audience even opens the message. Verified Mark Certificates (VMCs) from GlobalSign make that possible, helping brands show authenticated logos directly in inboxes a simple, powerful way to start building trust with mark certificates. In this article, we’ll explore the top methods to Strengthen brand credibility with mark certificates and share why you need them.
What Are Verified Mark Certificates?
A Verified Mark Certificate is a digital certificate that authenticates your organization’s identity and allows your verified logo to appear beside your emails in supported inboxes such as Gmail and Apple Mail. It’s the digital equivalent of putting your official seal on every message you send, reassuring recipients that the communication truly comes from you.
When recipients see your verified brand mark, they instantly recognize your legitimacy. That visual cue builds familiarity and confidence, reducing the likelihood of emails being ignored or flagged as suspicious.
Why Building Trust with Mark Certificates Matters
Trust is not built overnight. Every touchpoint between your brand and its audience either strengthens or weakens that trust. In email communication, where impersonation attempts are frequent, brand reputation is at constant risk.
By building trust with mark certificates, you demonstrate commitment to transparency and authenticity. Your logo acts as a symbol of verification — not a marketing gimmick. It reassures customers that your organization values data protection and secure digital experiences.
VMCs also complement DMARC compliance, enhancing your overall email security strategy. When paired with proper domain authentication, mark certificates create a visible layer of trust that customers can rely on with confidence.
The Business Benefits of Verified Mark Certificates: Strengthen Brand Credibility
Every opened email represents potential revenue, engagement, or long-term loyalty. Organizations using VMCs often see measurable improvements in open rates and brand recall. Recipients are more likely to engage when they recognize the sender’s verified logo, particularly in crowded inboxes.
Beyond marketing metrics, mark certificates signal that your brand is proactive about cybersecurity and user protection. This not only supports IT compliance but also elevates your corporate reputation across all communications.

Types Of Mark Certificates And When To Use Each

Use this quick table to decide which route fits your brand stage.
| Certificate Type | Trademark Required | Best For | Key Brand Benefit |
|---|---|---|---|
| Verified Mark Certificate (VMC) | Yes, registered trademark for your logo | Established brands, enterprises, public institutions | Strongest visual trust signal, often with checkmark in supported inboxes, ideal for high visibility brands |
| Common Mark Certificate (CMC) | No, logo must have consistent use history | Growing brands, startups, smaller organizations | Faster and more accessible way to show your logo in inboxes and build trust without full trademark process |
| No Mark Certificate (BIMI Only) | Not applicable, logo may still display in some cases | Brands just starting with email authentication | Limited or inconsistent logo display, weaker anti spoofing protection, fewer supported providers |
Note that both VMC and CMC still require proper DMARC and BIMI configuration, so email authentication is always the foundation.
Best Practices To Maximize The Value and Brand Credibility Using Mark Certificates
Once your Mark Certificate is live and your logo appears in inboxes, take a few extra steps to get full value.
- Align Email Design With The Inbox Avatar
Use the same logo variation, colors and visual tone inside your templates so the experience feels seamless from inbox view to opened message. - Educate Users Subtly
In security pages or onboarding flows, explain that legitimate emails will display your logo in supported inboxes and that suspicious messages without the logo should be treated carefully. - Monitor Performance Metrics
Watch open rates, click throughs and phishing related support tickets before and after implementation. Over a few months, you should see clearer patterns in engagement and fewer spoofing complaints. - Keep Authentication Clean: Strengthen Brand Credibility
As you add new tools and senders, make sure they authenticate correctly so they do not break your DMARC, BIMI and Mark Certificate setup.
With the right groundwork, Mark Certificates become more than a compliance badge. They turn every email into a small, repeated proof that your brand is real, careful and worth trusting.
