Display your logo in every inbox — no trademark required

A Common Mark Certificate (CMC) lets your organization show its established brand logo directly in the email sender field — all you need is a domain and a logo that’s been in active use for at least 12 months.

Brand recognition in the inbox — without a registered trademark

A CMC is a digital certificate that verifies your organization has established common-law rights to a logo through active use, and is authorized to display it in email clients that support BIMI (Brand Indicators for Message Identification). Unlike a VMC, a CMC does not require a registered trademark — it relies on demonstrated, continuous use of your logo on an owned domain.

Key Benefits

No trademark required

Instant brand recognition

Phishing & spoofing protection

What you need before applying

1
12 months of logo use
Your logo must have been in active, continuous use on a domain you own for at least 12 months. No trademark required.
2
DMARC enforcement
Your sending domain must have DMARC configured at p=quarantine or p=reject
3
SVG logo (Tiny P/S)
Your logo must conform to SVG Tiny P/S format for BIMI. SSL.com can advise on conversion.
4
BIMI DNS record
A BIMI TXT record added to your domain’s DNS after issuance. SSL.com provides step-by-step guidance.
Do you have a registered trademark? If your logo is formally registered with a recognized trademark office, you may qualify for a Verified Mark Certificate (VMC) — which provides a higher level of authentication and broader email client support.

Frequently asked questions

Gmail and Apple Mail currently support BIMI logo display — note that some clients, including Gmail, may require a VMC rather than a CMC for logo display. Fastmail also supports BIMI with a CMC. Yahoo Mail supports BIMI logo display but does not currently require any Mark Certificate for logos to appear in Yahoo applications. Check current BIMI provider documentation for the latest compatibility.
Your logo must have been continuously displayed on a domain you own for at least 12 months. Evidence typically includes website history, archived pages, marketing materials, or other documentation showing uninterrupted use.
A CMC is based on established common-law use of your logo (12+ months on an owned domain) and does not require a trademark. A VMC requires a registered trademark but provides a higher level of authentication and broader email client support. If you have a registered trademark, a VMC is recommended.
CMC validation typically takes 3–5 business days, depending on the completeness of your logo use documentation.
No — CMCs are domain-specific. Each sending domain requires its own certificate.
