Introduction
Brand Indicators for Message Identification (BIMI) is a powerful new email authentication standard that goes beyond just protecting against email fraud—it's about boosting brand visibility and user trust. By displaying a verified brand logo next to emails, BIMI not only enhances security but makes your emails stand out. Let’s dive into how BIMI works and why it’s a must-have for email-based brand protection.
What is BIMI?
BIMI is a cutting-edge protocol that enables brands to display their logo alongside authenticated emails, but there’s a catch—only emails with verified authentication can show it. BIMI works in tandem with established standards like SPF, DKIM, and DMARC, ensuring that only legitimate senders are trusted to show their logos.
BIMI Key Components:
Verified Mark Certificate (VMC): A certificate that validates the authenticity of your logo.
SVG-P/S Format: Logos need to meet specific standards, using scalable and secure SVG format.
How BIMI Enhances Brand Protection
BIMI isn’t just about logos; it's about securing your brand and building trust. Here’s how it works:
Visual Trust and Authenticity
When users see your verified logo, they know the email is genuine. It’s easier to spot phishing attempts, as fraudsters can’t use your logo without authorization.Stronger DMARC Compliance
BIMI requires a DMARC policy of either "quarantine" or "reject," ensuring your domain is protected against spoofing and impersonation.Reducing Phishing Risk
Thanks to DMARC enforcement, unauthorized entities can’t use your brand’s identity, significantly reducing phishing attempts.Brand Consistency
BIMI ensures the logo you display is consistent across all email communications, solidifying your brand’s integrity.
Technical Requirements for BIMI Implementation
Ready to get started? Here’s what you need to do:
Set Up SPF, DKIM, and DMARC
These authentication protocols are your foundation. DMARC must be set to "quarantine" or "reject" for full protection.Create a BIMI-Compatible Logo
Your logo needs to be in the secure and scalable SVG-P/S format to meet BIMI requirements.Get a Verified Mark Certificate (VMC)
Obtain a VMC from a trusted certificate authority, like DigiCert, to verify your logo.Publish Your BIMI DNS Record
Update your DNS settings with a BIMI record that links to your logo and VMC. Here’s a sample record:arduinoCopy codedefault._bimi.example.com TXT "v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem"
Verifying BIMI Implementation
Once you've set everything up, here’s how you can verify BIMI is working:
Use BIMI lookup tools to confirm your DNS record is correctly configured.
Send test emails to supported clients (e.g., Gmail, Yahoo) and see if your logo appears.
Limitations to Keep in Mind
While BIMI is powerful, there are a few things to consider:
Limited Client Support: Not all email clients support BIMI yet.
VMC Requirement: You must have a Verified Mark Certificate for full compliance.
Logo Compliance: Your logo must meet BIMI's SVG-P/S format standards to avoid rejection.
Conclusion
BIMI is more than just a logo on an email—it’s a powerful tool for protecting your brand from email fraud and boosting trust with your audience. By enforcing DMARC compliance and verifying your logo, BIMI ensures only legitimate emails bear your brand’s mark, offering a proactive defense against phishing and impersonation.
