Providers With Full BIMI Support
Gmail
- Status: Full support with VMC requirement
- VMC required: Yes, for logo display
- Verification badge: Shows blue checkmark with VMC
- Display location: Avatar position in inbox and message view
- Requirements: DMARC enforcement (p=quarantine minimum)
Gmail is the most important BIMI target for most senders due to its large user base and strict VMC requirement that adds credibility to the verification.
Yahoo Mail
- Status: Full support without VMC requirement
- VMC required: No (optional)
- Display location: Avatar in inbox list
- Requirements: DMARC enforcement
Yahoo was an early BIMI adopter. You can display your logo on Yahoo without the VMC investment, making it a good place to start.
AOL
- Status: Same as Yahoo (same parent company)
- VMC required: No
- Requirements: Same as Yahoo Mail
Apple Mail
- Status: Full support with VMC
- VMC required: Yes, for verified display
- Display location: iOS and macOS Mail apps
- Requirements: DMARC enforcement plus VMC
Apple Mail's BIMI support extends to iPhone, iPad, and Mac Mail applications.
Market Coverage
Gmail holds approximately 30% of global email market share. Combined with Yahoo, AOL, and Apple Mail users, BIMI-supporting providers represent over half of consumer email users.
Providers Without BIMI Support
Microsoft Outlook
- Status: No BIMI support (as of early 2026)
- Includes: Outlook.com, Hotmail, Live.com, Outlook 365
- Future: Microsoft has not announced BIMI plans
Microsoft's lack of BIMI support is significant given Outlook's large business user base. If your audience is primarily business email, BIMI's immediate value is reduced.
Corporate Email Systems
Most corporate email systems do not support BIMI:
- Microsoft Exchange (on-premises)
- Google Workspace (different from consumer Gmail)
- Third-party corporate email solutions
Regional Providers
Many regional email providers do not support BIMI:
- European providers (GMX, Web.de, etc.)
- Asian providers
- Local ISP email services
BIMI Support Comparison
VMC Required vs Optional
- VMC Required: Gmail, Apple Mail
- VMC Optional: Yahoo, AOL
With VMC, you get logo display on all supporting providers. Without VMC, only Yahoo and AOL show your logo.
Implementation Differences
Each provider may handle BIMI slightly differently:
- Logo caching timing varies
- Display size and position differs
- Verification indicators vary
Calculating Your BIMI Reach
To understand BIMI's value for your audience:
- Export your email list by domain
- Calculate percentage on Gmail domains (@gmail.com)
- Add Yahoo domains (@yahoo.com, @ymail.com)
- Add AOL domains (@aol.com)
- Estimate Apple Mail users (harder to identify by domain)
If 40%+ of your list uses supporting providers, BIMI provides significant reach.
Future Outlook
