# BIMI Explained: your logo in the inbox

BIMI puts your brand's verified logo next to your emails in supporting inboxes — a trust signal and an anti-spoofing reward. Here's what it is, what it requires, and whether it's worth it.

You've seen it: some emails show a little brand logo next to the sender, while others show a generic placeholder. That logo isn't decoration — it's BIMI , and it's both a trust signal for recipients and a reward for getting your email security right. Here's the rundown.

## What BIMI is

BIMI (Brand Indicators for Message Identification) is a standard that lets your verified brand logo appear next to your emails in supporting inboxes (Gmail, Apple Mail, Yahoo and others). Instead of a generic avatar, recipients see your logo — a small but powerful signal that the mail is genuinely from you.

Without BIMI With BIMI

Generic initial/avatar Your verified brand logo

No visual trust cue Instant brand recognition

## Why it matters

- Trust — a recognised logo reassures recipients the mail is legitimate, which can lift open rates.

- Anti-spoofing — because BIMI requires strong authentication, a spoofer can't show your logo. It makes impersonation visibly harder.

- Brand presence — your logo in every inbox is free, repeated brand exposure.

## What BIMI requires

This is the catch — and the point. BIMI isn't a quick toggle; it sits on top of solid email security:

Requirement Why

Enforced [DMARC](/blog/dmarc-setup-guide) ( quarantine or reject ) You must prove your mail is locked down first

A logo in SVG format The image to display

A VMC (in many inboxes) A Verified Mark Certificate proving you own the logo/trademark

That middle and last requirements are the gatekeepers: you can't get your logo in the inbox until you've enforced DMARC, and (for Gmail and others) paid for a VMC that verifies your logo is really yours.

BIMI is the carrot for doing email security right. You can't enable it until you've reached DMARC enforcement — so it's both a benefit and an incentive to finish the [SPF/DKIM/DMARC](/blog/spf-dkim-dmarc-explained) work you should be doing anyway.

## Is it worth it?

It's worth it if… Maybe skip if…

You send lots of customer email You barely send mail

Brand recognition matters to you You're pre-DMARC-enforcement

You've already enforced DMARC The VMC cost outweighs the benefit

For brands that send significant volumes of customer mail and have already enforced DMARC , BIMI is a low-effort win (you've done the hard part). If you haven't enforced DMARC yet, that's the prerequisite to tackle first — BIMI is the reward at the end.

## A monitoring connection

BIMI depends on enforced DMARC, which depends on your [SPF/DKIM/DMARC records](/blog/spf-dkim-dmarc-explained) staying intact. If those drift, you don't just lose the logo — your mail can start failing. [Monitoring your email policy](/docs/monitors/email) keeps the whole chain healthy.

## The bottom line

In one line

What Your verified logo shown next to your emails.

Requires Enforced DMARC + an SVG logo + (often) a VMC.

Why Trust, brand presence, harder to spoof.

First Reach DMARC enforcement — BIMI is the reward.

BIMI turns email security into a visible brand benefit: do the [DMARC](/blog/dmarc-setup-guide) work, and your logo greets customers in their inbox. It's the cherry on top of a properly authenticated email program — not a shortcut around it.
