BIMI Checker and Record Inspector

BIMI works by allowing you to publish a specific record in your domain’s DNS that includes a secure link to your brand logo and, optionally, a Verified Mark Certificate (VMC).

When you send an email to a BIMI-supported mailbox provider, that provider checks your domain’s DMARC policy and verifies that the message passes authentication. If both checks are successful, the provider retrieves the logo from your BIMI record and displays it next to your message in the inbox.

To implement BIMI successfully, your domain must already have key email authentication protocols in place. Here’s what you’ll need:

• A DMARC policy set to p=quarantine or p=reject to ensure enforcement
• A Verified Mark Certificate (VMC), which some mailbox providers require
• Your brand’s logo hosted at a secure HTTPS URL in SVG format
• Your VMC file hosted at a secure HTTPS URL in .pem format
• A valid BIMI record published in your DNS

BIMI builds on strong email authentication to enhance your organisation’s credibility and visibility. When your verified logo appears in supported inboxes, recipients can immediately identify your brand as legitimate and trustworthy.

This visual verification reinforces brand recognition, reduces the likelihood of phishing or spoofing attempts, and demonstrates your commitment to email security. For Australian businesses, adopting BIMI can strengthen both customer confidence and digital reputation.

You can use EasyDMARC’s free BIMI Lookup Tool to check, view, and validate your BIMI record instantly. Simply enter your domain name, and the tool will retrieve your record from DNS, analyse its components, and show whether your logo and Verified Mark Certificate (VMC) are correctly configured.

Enter your domain name into the checker and select Check BIMI. The tool will instantly retrieve your BIMI record, verify your logo and VMC, and show how your logo appears in supported mailboxes.

Just input your domain name and click the “Check BIMI” button. You’ll receive your BIMI validation results right away.

No, BIMI is not mandatory. However, it is widely recognised as a best practice for improving brand trust and email security. Implementing BIMI alongside DMARC enforcement helps recipients verify that your messages are authentic, strengthens your domain’s reputation, and improves overall inbox visibility.
