Apple Mail, Yahoo Mail, and Fastmail display BIMI logos without requiring a Verified Mark Certificate. Only Gmail requires a VMC. If your recipients primarily use these providers, you can implement BIMI for free — just set up DMARC enforcement, create an SVG Tiny PS logo, and publish the BIMI DNS record without the a= tag.
BIMI Without a VMC: Which Providers Support It
Provider Support Without VMC
| Provider | Shows Logo Without VMC? | DMARC Required? |
|---|---|---|
| Apple Mail | Yes | p=quarantine+ |
| Yahoo Mail | Yes | p=quarantine+ |
| Fastmail | Yes | p=quarantine+ |
| Gmail | No — requires VMC | p=quarantine+ |
| Microsoft Outlook | No BIMI support | N/A |
That means a BIMI record without a VMC gets your logo in front of Apple, Yahoo, and Fastmail users — which is a substantial audience for zero additional cost.
Setup for VMC-Free BIMI
1. Confirm DMARC Enforcement
Your DMARC policy must be at p=quarantine or p=reject. Check with:
dig TXT _dmarc.yourdomain.com +short
If you're still at p=none, advance your policy first.
2. Create Your SVG Tiny PS Logo
Your logo must be in SVG Tiny PS format. Key requirements:
- Square dimensions
- Solid background (no transparency)
- No scripts, animations, or external references
baseProfile="tiny-ps"declaration
3. Host the Logo
Upload the SVG to an HTTPS URL on your domain. For example:
https://yourdomain.com/bimi/logo.svg
Make sure the URL:
- Uses HTTPS
- Is publicly accessible
- Serves
Content-Type: image/svg+xml
4. Publish the BIMI Record
Type: TXT
Host: default._bimi
Value: v=BIMI1; l=https://yourdomain.com/bimi/logo.svg
No a= tag needed. The record is valid without it.
Practitioner note: I set up BIMI without a VMC for every client who has DMARC enforcement in place. It's free, takes 15 minutes, and gets your brand visible on Apple devices and Yahoo. There's no reason not to do it.
Upgrade Path to VMC
When you're ready to add Gmail support:
- Register your trademark (if not already done — takes 6-12 months)
- Obtain a VMC from DigiCert or Entrust (~$1,500/year)
- Host the VMC PEM file at an HTTPS URL
- Update your BIMI record:
v=BIMI1; l=https://yourdomain.com/bimi/logo.svg; a=https://yourdomain.com/bimi/vmc.pem
The existing logo and record structure stay the same. You're just adding the a= tag.
Practitioner note: Start without a VMC to validate your BIMI setup works. Get the logo showing on Apple and Yahoo, confirm the SVG format is correct, then invest in the VMC when you're ready. This de-risks the $1,500 spend.
If you want BIMI implemented — with or without a VMC — I can handle it end to end.

Frequently Asked Questions
Which email providers show BIMI without a VMC?
Apple Mail (iOS 16+, macOS Ventura+), Yahoo Mail, and Fastmail display BIMI logos without requiring a VMC.
Is BIMI without a VMC still worth it?
Yes. Apple Mail and Yahoo account for a significant share of email users. Getting your logo showing on these platforms costs nothing beyond the DMARC enforcement you should already have.
What's the BIMI record format without a VMC?
v=BIMI1; l=https://yourdomain.com/logo.svg — omit the a= tag entirely, or set it to a=self for providers that accept self-asserted logos.
Can I add a VMC later?
Yes. Start with BIMI without a VMC, then add the a= tag later when you obtain a VMC. The l= tag stays the same.
Do I still need DMARC enforcement without a VMC?
Yes. All BIMI implementations require DMARC at p=quarantine or p=reject, regardless of VMC status.
