Free BIMI Record Generator

Your Generated BIMI Record

TXT Record for: default._bimi.[your-domain]

v=BIMI1

Domain Name

Enter your domain to personalize the DNS record location and validate your configuration.

International domains are supported (e.g., münchen.de)

BIMI Configuration

Deep SVG checks limited in browser (CORS). Ensure baseProfile=tiny-ps and other BIMI rules.

Logo URL (l) - Required

Must be HTTPS URL to an SVG Tiny P/S file. No scripts, animations, or external references allowed. View SVG requirements

VMC Certificate URL (a) - Optional

HTTPS URL to a Verified Mark Certificate (PEM format). Required by Gmail, optional for Yahoo. Learn about VMCs

Selector - Advanced (Optional)

Use custom selectors for different logos/campaigns. Default is "default". Learn about selectors

Prerequisites for BIMI

DMARC at enforcement: Your domain must have DMARC with p=quarantine or p=reject
SVG logo hosted: Square aspect ratio, centered artwork, filled background (not transparent)
Stable HTTPS hosting: Logo and VMC must be served over HTTPS with long cache headers
VMC for Gmail: Gmail requires a valid VMC from authorized CAs (Sectigo, DigiCert)

Logo Requirements Checklist

Technical Requirements

✓ SVG Tiny P/S profile (not full SVG)
✓ No JavaScript or animations
✓ No external references or links
✓ File size under 32KB recommended
✓ Served over HTTPS only

Design Requirements

✓ Square aspect ratio (1:1)
✓ Centered logo with safe margins
✓ Solid background (not transparent)
✓ Single logo mark preferred

How to Deploy Your BIMI Record

1
Verify DMARC enforcement: Ensure your domain has p=quarantine or p=reject.
2
Host your SVG logo: Upload to a stable HTTPS URL with proper cache headers.
3
Copy the generated record using the button above.
4
Create a new TXT record in your DNS with:
- • Name/Host: default._bimi
- • Type: TXT
- • Value: Your generated BIMI record
- • TTL: 3600 (or your provider's default)
5
Wait for DNS propagation (usually 30 minutes to 24 hours).
6
Test with major providers: Send test emails to Gmail/Yahoo seed accounts.

⚠️ Important: The record must be created at default._bimi.[your-domain]. The underscore prefix and subdomain structure are required.

Why Use This Free BIMI Builder?

Instant BIMI Record Creation

Generate valid BIMI DNS records in seconds. No complex syntax to learn — configure your logo URL and optional VMC to get a production‑ready BIMI record.

Real-Time Validation

Every BIMI record is validated for proper format. The builder checks for HTTPS requirements and warns about common configuration issues before deployment.

Build Brand Trust

Display your verified logo next to every email in customer inboxes. Visual brand recognition increases open rates and protects against phishing.

VMC Provider Guidance

Understand when you need a Verified Mark Certificate and which providers offer them. Get clear requirements for Gmail logo display.

BIMI Best Practices

• Ensure DMARC is at enforcement (p=quarantine or p=reject) before deploying BIMI
• Test your SVG logo meets all requirements using online validators
• Consider VMC investment for Gmail visibility (required by Google)
• Monitor logo display in test accounts before full deployment
• Use our free DMARC checker to verify prerequisites

VMC/CMC Certificate Providers

Gmail requires an approved BIMI certificate and DMARC enforcement. This can be a Verified Mark Certificate (VMC) — and, where supported, a Common Mark Certificate (CMC) — issued by an approved Certificate Authority.

VMC vs CMC: Key Differences

What they are: Both are X.509 certificates used by BIMI and referenced via the a= tag (PEM URL). They play the same technical role in validating logo use.
Trademark requirement (VMC): Requires an active, registered trademark from an accepted trademark office that matches the logo/brand. Issued by CAs such as DigiCert or Sectigo after organization and trademark verification.
Eligibility (CMC): Designed to cover brands that may not have a registered trademark. Validation relies on alternative evidence (e.g., documented common‑law rights/usage) plus standard org verification. Availability and acceptance vary by CA and mailbox provider.
Provider support: Mailbox provider policies evolve. Confirm current acceptance of CMC vs VMC with your CA and target providers (e.g., Gmail/Yahoo). When in doubt, a VMC with a registered trademark is the most universally accepted option.
Cost/renewal: Similar annual pricing (roughly €900–€1,500) and renewal cadence; expect identity re‑validation and ongoing eligibility checks.

Tip: Your BIMI TXT syntax is identical for VMC or CMC — only the certificate contents and how they’re validated differ.

Sectigo

Offers both VMC and CMC options with trademark verification services

DigiCert

Global certificate authority offering VMC issuance with comprehensive validation

VMC/CMC certificates typically cost €900–€1,500 annually. Exact requirements and acceptance (especially for CMC) depend on the CA and mailbox provider.
