BIMI Explained: Get Your Logo in the Inbox and Build Trust
What BIMI is, why it boosts open rates and trust, and exactly how to set it up alongside your email authentication.
Marcus Webb
Email Marketing Specialist
BIMI — Brand Indicators for Message Identification — puts your verified logo next to your emails in supporting inboxes. It is a small visual cue with an outsized effect on trust and open rates.
BIMI is built on authentication. Before a logo can appear, you need SPF, DKIM, and an enforced DMARC policy. In other words, BIMI rewards the senders who have already done deliverability right.
“The trust payoff is real. A recognizable, verified logo signals legitimacy at a glance, helping recipients distinguish your genuine mail from spoofs and phishing — and brands that adopt it commonly see measurable open-rate lifts.
Some inboxes require a Verified Mark Certificate, which ties your logo to a registered trademark. It adds cost and effort, but it unlocks the blue checkmark experience in the providers that demand it.
Get the logo file right. BIMI requires a specific square SVG format, so most brands need to prepare a compliant version of their mark before publishing the BIMI DNS record.
“For any brand serious about email, BIMI is a logical next step after DMARC enforcement: a visible, trust-building reward for sending authenticated, legitimate mail.
