What Are Mark Certificates?
Mark Certificates are digital certificates that display your brand’s logo next to your emails in inboxes like Gmail and Apple Mail, improving brand recognition, increasing email engagement, and ensuring email security. There are two types:
- Verified Mark Certificates (VMCs) – Require a trademarked logo and provide a blue checkmark in Gmail for verified brands.
- Common Mark Certificates (CMCs) – Do not require a trademarked logo but still display your logo in email inboxes.
With the rise of phishing and email fraud, VMCs and CMCs provide a trustworthy visual indicator that your emails are legitimate, boosting customer confidence and brand consistency.
5 Powerful Reasons to Get a Mark Certificate Today
Boost Your Brand’s Visibility
When recipients receive your emails, they will see your verified logo instead of a default initial or blank space, making your emails stand out in crowded inboxes. Studies show that VMC certificates can increase email engagement by 10% or more.
Enhance Email Security & Prevent Phishing
With a CMC or VPM certificate, your logo will only appear if the email is authenticated through the DMARC (Domain-based Message Authentication, Reporting, and Conformance) protocol. This helps prevent phishing attacks and ensures only authorized emails are sent under your domain.
Gain Customer Trust with Verification
A blue checkmark (for VMCs) or a validated logo (for CMCs) signals to your recipients that your email is legitimate, secure, and not a scam.
Improve Email Deliverability
By enforcing DMARC policies (quarantine or reject), your emails are less likely to be marked as spam, ensuring better email deliverability rates.
Future-Proof Your Email Marketing
Google, Apple, Yahoo, and other major email providers are increasingly supporting BIMI (Brand Indicators for Message Identification), the protocol that powers VMCs and CMCs. Early adopters gain a competitive advantage by adopting this technology now.
