What is BIMI? A Plain-English Guide
BIMI (Brand Indicators for Message Identification) is a standard that displays your verified logo next to your emails in supporting inboxes. It requires a passing DMARC policy (p=quarantine or reject) and, for Gmail, a Verified Mark Certificate (VMC).
Why it matters for deliverability
Understanding BIMI is part of strong authentication that also builds trust and open rates. Get it right and more of your mail reaches the inbox; get it wrong and even legitimate mail can be filtered.
