Why does one brand's logo show up in the inbox, and yours doesn't?You've seen it. A brand emails you, and there's their actual logo sitting next to the message, not a blank circle or a gray initial. That's BIMI. And it isn't a design trick. It's a reward for doing your email authentication right.
⬡ browser-mock, inbox list: one row shows a real brand logo, the rows above show plain gray initialsBIMI stands for Brand Indicators for Message Identification. In plain words: it displays your verified logo next to your emails in inboxes that support it. Gmail, Apple Mail, Yahoo, Fastmail, and a growing list of others.
⬡ browser-mock, harborpost.net row, lighthouse logo fades in beside the sender nameA logo you can't fake.Here's the problem it solves. People genuinely struggle to tell a real email from a spoofed lookalike. A verified logo in the inbox is visual proof that the sender is who they claim to be. It's an anti-phishing signal and a brand-visibility win rolled into one.
⬡ split-compare, LEFT real harborpost.net with logo · RIGHT spoofed lookalike, blank icon, no logo to stealBIMI is the reward for doing DMARC right.This is the part most people miss. BIMI only shows up if your domain is at DMARC enforcement, meaning a policy of p=quarantine or p=reject. That's the hard prerequisite, and it's where most senders haven't reached yet. No enforced DMARC, no logo. Think of BIMI as the trophy for taking your authentication seriously. New to DMARC? There's a whole video on it, linked below.

So getting BIMI live takes four things. One, DMARC at enforcement. Two, a logo in a specific format called SVG Tiny P/S. Three, a BIMI DNS record pointing to that logo. And four, for Gmail specifically, a Verified Mark Certificate, a paid credential that proves you own the logo.
⬡ checklist, four items check off: DMARC enforced · SVG P/S logo · BIMI DNS record · VMC (Gmail)That certificate costs money, often somewhere around one thousand to fifteen hundred dollars a year, which is why BIMI adoption leans toward bigger brands. Good news: Apple Mail and Yahoo don't require it. So if you're already at DMARC enforcement, logo display there is within reach with just the DNS record.

Brand Indicators for Message Identification displays your verified brand logo next to your emails in supporting inboxes like Gmail, Apple Mail, Yahoo, and Fastmail.
