BIMI — Brand Indicators for Message Identification — is the protocol that puts your company logo next to your emails in the recipient's inbox. It is the visual cherry on top of a properly authenticated email infrastructure.
For cold email, BIMI serves a specific purpose: it makes your emails look legitimate and recognizable in a sea of unknown senders. When a prospect sees a branded logo next to your email instead of a generic initial or avatar, trust increases and open rates follow.
At imisofts, we offer BIMI setup as an optional add-on to our infrastructure packages. Here is how it works and whether it makes sense for your campaigns.
What BIMI does
BIMI displays your brand logo (your company logo or a relevant brand image) next to your emails in supporting email clients. Gmail, Yahoo, and Apple Mail all support BIMI.
When a recipient sees your email in their inbox, instead of a generic colored circle with an initial, they see your actual brand logo. This visual indicator signals legitimacy and brand recognition.
BIMI works on top of your existing authentication stack. It requires a valid DMARC policy at p=quarantine or p=reject, which means your SPF and DKIM must already be passing. BIMI is the final layer — it rewards you for having a properly authenticated setup.
Prerequisites for BIMI
BIMI has specific prerequisites that make it an advanced feature, not a starting point.
Your DMARC policy must be at p=quarantine or p=reject. A p=none policy does not qualify for BIMI. This means your SPF and DKIM must be fully configured and consistently passing authentication checks.
You need a Verified Mark Certificate (VMC) from an authorized certificate authority. This is a digital certificate that verifies your ownership of the brand logo. VMCs are issued by DigiCert and Entrust, and typically cost $1,000 to $1,500 per year.
Your logo must be in SVG Tiny PS format — a specific SVG format required by the BIMI standard. Standard SVG files will not work. The logo should be square, simple, and recognizable at small sizes.
Setting up BIMI
Once prerequisites are met, BIMI setup involves adding a single DNS TXT record.
The record goes to the hostname default._bimi.yourdomain.com with a value that points to your logo file and VMC certificate.
The format is: v=BIMI1; l=https://yourdomain.com/path/to/logo.svg; a=https://yourdomain.com/path/to/vmc.pem
The logo SVG file and VMC certificate need to be hosted at publicly accessible URLs. We typically host them on the same server as the email infrastructure.
After adding the DNS record, email clients that support BIMI will begin displaying your logo next to emails from that domain. It can take a few days for the change to propagate and start appearing.
Is BIMI worth it for cold email?
This depends on your campaign volume, brand maturity, and budget.
BIMI makes the most sense for clients running high-volume campaigns (25+ domains) where brand recognition matters. If you are sending 2,500+ emails per day to the same market over months, having your logo visible in every inbox builds cumulative brand awareness.
For smaller operations (under 10 domains), the $1,000 to $1,500 annual VMC cost may not justify the incremental open rate improvement. The cost per domain for the certificate can be significant when spread across only a few domains.
At imisofts, we recommend BIMI for Professional and Enterprise package clients who have established brands and plan sustained, long-term cold email campaigns. For Starter and Micro clients, the priority should be getting the core infrastructure — DNS, warmup, and rotation — performing before adding advanced features.
Conclusion
BIMI is the most advanced layer of email authentication, and it rewards properly configured infrastructure with visible brand presence in the inbox. It is not where you start, but where you graduate to once your core deliverability is solid.
