BIMI lets brands display a verified logo next to emails in supporting inboxes. Learn what BIMI is, prerequisites like DMARC, and why it matters.
BIMI (Brand Indicators for Message Identification) is an email specification that allows a brand’s logo to appear next to authenticated messages in participating inboxes. It’s designed to increase trust and make legitimate messages more recognizable to recipients.
BIMI typically requires strong domain protection, often including an enforced DMARC policy, and a properly configured BIMI DNS record that points to a hosted logo file. Some ecosystems also require verified certificates, depending on the provider.
When implemented correctly, BIMI can improve brand recognition and reduce confusion with impersonation attempts. It doesn’t replace deliverability fundamentals, but it complements authentication by making trusted messages visually consistent.
