Summary
Display of BIMI logos in Yahoo generally takes a few days to a week after setup, though no definitive timeline is guaranteed. Display is limited to commercial and transactional emails and relies heavily on Yahoo's internal reputation scoring, user engagement, and consistent sending volume. DMARC enforcement (p=quarantine or p=reject) and a Validated Mark Certificate (VMC) are prerequisites. Smaller senders may face hurdles meeting Yahoo's BIMI requirements. BTinternet adds BIMI status to the `Authentication-Results` header, but this isn't universal. BIMI validators can check configuration, but don't guarantee display.
Key findings
- Display Time: A few days to a week is typical, but not guaranteed.
- Reputation is Key: Yahoo's internal reputation is a primary factor.
- Engagement Influences: Open and click-through rates impact display probability.
- DMARC/VMC Essential: DMARC enforcement (p=quarantine/reject) and VMC are required.
- Limited Header Info: BIMI status in `Authentication-Results` header isn't universal.
- Email type: Only commercial and transactional emails are eligible.
Key considerations
- Improve Reputation: Actively improve sender reputation with Yahoo.
- Drive Engagement: Focus on increasing open and click-through rates.
- Comply with Requirements: Ensure DMARC is enforced and a valid VMC is in place.
- Monitor Headers: Check for BIMI status in headers, but don't rely on its presence.
- Be Patient: Logo visibility may take time even after setup, so check back often.
- Verify Configuration: Use validators to confirm your BIMI record and SVG file are properly configured, even if this doesn't guarantee immediate display.
What email marketers say
11 marketer opinions
The time it takes for a BIMI logo to appear in Yahoo mailboxes can vary, with estimates ranging from a few days to a week after all technical requirements are met. The display of the BIMI logo in Yahoo depends on multiple factors beyond just technical setup, including sender reputation, sending volume, engagement metrics (open and click-through rates), and Yahoo's internal algorithms. While some email providers add BIMI status to the `Authentication-Results` header, this isn't universally implemented. Checking record syntax, SVG format and DMARC compliance is crucial for compatibility.
