BIMI Checker
Verify your BIMI logo record
What is it?
BIMI (Brand Indicators for Message Identification) lets your verified logo appear next to your emails in supporting inboxes, but only once your domain already has strong DMARC enforcement in place.
Why it matters
It's a visible trust signal — recipients recognize your brand at a glance, reinforcing that a message is genuinely from you and not a look-alike phishing attempt.
Impact if ignored
A missing or misconfigured BIMI record just means your logo won't show up — there's no deliverability penalty on its own, but it's a good sign of DMARC maturity when it's there.
Common use cases
- Confirm your logo record is live after reaching DMARC quarantine/reject
- Verify your logo and authority-evidence URLs are actually reachable
