BIMI Record Checker
Enter your domain to verify your BIMI record configuration and confirm your brand logo displays correctly in email inboxes.
What Is BIMI?
BIMI stands for Brand Indicators for Message Identification. It is an email authentication standard that lets you display your brand logo next to your emails in supported inboxes. When a recipient sees your message, they also see your verified logo.
BIMI works on top of DMARC. Your domain must have a DMARC policy set to quarantine or reject before mailbox providers display your logo. This requirement ensures only authenticated senders get the visual branding benefit.
Gmail and Apple Mail both document BIMI support, with different certificate rules (compared below). In our October 2026 scan of the Tranco top 1,000, 161 domains published a BIMI record.
How BIMI Works
1. Enforce DMARC
Set your DMARC policy to p=quarantine or p=reject, with no pct below 100. BIMI requires enforcement before your logo appears in inboxes.
2. Publish a BIMI Record
Add a BIMI TXT record to your DNS at default._bimi.yourdomain.com. The record points to your SVG logo and your mark certificate.
3. Obtain a Mark Certificate
Apply for a Verified Mark Certificate (VMC) or a Common Mark Certificate (CMC) from an authorized certificate provider. A VMC needs a registered trademark or government mark. A CMC does not; the most common route is proof the logo was on your website at least 12 months ago.
BIMI Requirements
DMARC p=quarantine or p=reject
Your domain must have a DMARC policy set to quarantine or reject. Subdomains must not be set to sp=none, and a leftover pct below 100 is not accepted. BIMI does not work with a p=none policy.
SVG Logo
Your logo must be an SVG file in the SVG Tiny Portable/Secure (SVG P/S) profile, with a square aspect ratio. Each mailbox provider decides the display size.
Mark Certificate (VMC or CMC)
Gmail accepts a VMC (logo with a checkmark) or a CMC (logo, no checkmark). Apple Mail needs a BIMI evidence document such as a VMC; Apple does not say whether a CMC counts. See the comparison below.
DNS TXT Record
Publish the BIMI record in your DNS at default._bimi.yourdomain.com. The record contains the https URLs for your logo and certificate.
VMC vs CMC: which certificate you need
Get a VMC if the logo is a registered trademark and the Gmail checkmark matters to you. Get a CMC if it is not registered: Gmail still shows the logo, just without the checkmark. For Apple Mail, Apple asks for a “BIMI Evidence Document” and gives a VMC as its example. It does not say whether a CMC counts.
| VMC (Verified Mark Certificate) | CMC (Common Mark Certificate) | |
|---|---|---|
| What the CA verifies | A registered trademark or a government mark | One of three: prior use (the same logo on your domain at least 12 months before verification, checked on archive.org), a modified registered trademark, or a provisional mark |
| Trademark needed | Yes | No |
| Gmail | Logo with the verified checkmark | Logo, no checkmark |
| Apple Mail | Named by Apple as an example of a BIMI evidence document | Not stated |
Where the logo shows
| Mail client | With a VMC | With a CMC | Notes |
|---|---|---|---|
| Gmail (web, Android and iOS apps) | Logo and checkmark | Logo only | CMC support and the checkmark in the mobile apps arrived in September 2024. Google says the checkmark does not appear when Gmail is read in Apple Mail or other apps. |
| Apple Mail (iOS 16, iPadOS 16, macOS Ventura 13 or later, iCloud.com) | Logo, when the recipient's mail provider supports it | Not stated | The recipient's mail provider must be on the BIMI Group's list, verified by Apple, check the evidence document and add the BIMI headers. Otherwise no logo appears. |

Benefits of BIMI
Brand Visibility
Your logo appears next to every authenticated email you send. Recipients recognize your brand instantly in crowded inboxes.
Trust & Credibility
A verified logo signals authenticity. Recipients see your brand identity before they open the message.
Phishing Protection
When your legitimate emails display a verified logo, spoofed messages without the logo stand out. Recipients spot fakes faster.
Email Engagement
A familiar logo helps recipients notice your messages and recognize them as yours.
Frequently Asked Questions
BIMI stands for Brand Indicators for Message Identification. It is an email standard that lets you display your brand logo next to your messages in supported inboxes. BIMI gives recipients a visual cue to verify the sender before opening the email.
BIMI lets a mailbox provider show your logo next to messages that pass DMARC. When a message passes DMARC, your policy is at quarantine or reject, and your BIMI record is valid, a supporting provider can display your logo in the inbox. The logo is an SVG file referenced in your BIMI DNS record.
BIMI requires a DMARC policy of p=quarantine or p=reject on your organizational domain, with no pct below 100. You also need an SVG Tiny Portable/Secure logo on a public https URL and a BIMI TXT record in your DNS. Gmail accepts a VMC or a CMC. Apple Mail needs a BIMI evidence document, for example a VMC.
A Verified Mark Certificate is issued by an authorized certificate authority and confirms your logo is a registered trademark or government mark owned by your organization. In Gmail a VMC adds a verified checkmark next to the logo. Apple names a VMC as an example of the evidence Apple Mail relies on.
First, enforce DMARC at quarantine or reject. Second, create an SVG Tiny Portable/Secure logo file and host it on a public https URL. Third, obtain a VMC or CMC from an authorized provider. Fourth, publish a BIMI TXT record at default._bimi.yourdomain.com pointing to your logo and certificate.
A CMC is a BIMI certificate for a logo that is not a registered trademark. The BIMI Group's rules allow three kinds: prior use (the logo appeared on your domain at least 12 months earlier, checked on archive.org), a modified registered trademark, and a provisional mark. Gmail shows a CMC logo without the verified checkmark.
BIMI does not directly affect deliverability scores. It does require DMARC enforcement, which improves your sender reputation and authentication results. The combination of enforcement and brand visibility often leads to better engagement metrics over time.
