Email marketing is a business where professional are always looking for the next advantage. After all, it is a feast of famine game to get better visibility in front of subscribers and get messages opened.
BIMI, pronounced “bih-mee” may be the solution email marketers been dreaming about.
Brand Indicators for Message Identification, or BIMI is a new standard created to make it easier to get your logo displayed next to your message in the inbox. Not only will this help your visibility, but BIMI is designed to prevent fraudulent emails and aide deliverability, too.
Sounds good, huh? Let’s dig in and see how it works.
WHAT IS BIMI?
BIMI is a new way for verifying information about your brand. Like DMARC, DKIM, and SPF—three methods for verifying sender information—BIMI is a text record that lives on your servers. In fact, it works right alongside SPF, DMARC, and DKIM to signal to email clients that you are you.
BIMI is different in that it also allows you to display your company logo in supported inboxes, putting your brand front-and-center for subscribers.

HOW DOES BIMI WORK?
Like other email authentication standards, BIMI is essentially a text file. That text file follows a specific format and lives on your sending servers.
When a message is delivered, the recipient’s email service looks up the BIMI text file—and where it’s hosted—to ensure that the message can be verified. Once verified, the BIMI file tells the email service where to find the sender’s logo and the email service pulls that logo into the inbox.
Although the underlying concept of BIMI sounds simple, there are a few key things to keep in mind when setting up BIMI for your own brand:
You need additional authentication records set up for BIMI to work, including SPF, DKIM, and DMARC.
You need to have access to your domain name servers to set up a new BIMI DNS entry.
You must use an SVG file for your logo.
Additionally, at the time of writing the only inbox provider that supports BIMI is Yahoo! Mail, which is a member of the working group developing the new standard. Other email clients will likely add BIMI support in the coming year but, depending on your ability to do the above, it may be a lot of work with limited payoff—at least for now.
Agari, part of the BIMI working group, put together a great post on how to get started with BIMI, including an example of what a typical BIMI text record looks like. If you really want to dig deep, you can check out the official BIMI working group’s Brand Indicators for Message Identification working draft, which goes into exceptional detail around how BIMI works for both senders and recipient mail transfer agents.
SUCCESSFUL EMAIL MARKETING IS BUILT ON TRUST
The initial value of BIMI for email marketers should be obvious: you get your logo to display next to your messages in supported inboxes. But the real value is in establishing trust with your brand’s emails.
The underlying goal of BIMI is to make it easy for subscribers to identify trustworthy message senders so they can trust the content in their inbox. When subscribers see your logo, they can immediately trust that it’s an actual email from you and not a dangerous phishing attempt. Sure, the brand awareness of constantly seeing logos is nice, but the trust that comes along with those logos is where the magic happens.
BIMI should be beneficial to your deliverability, too. Since so much of modern-day deliverability is based on authentication and reputation—rather than email content itself—BIMI will provide yet another mechanism to improve your odds of making it to the inbox.
As we saw earlier, BIMI requires other authentication protocols to be properly set up. For brands not using SPF, DKIM, and DMARC, the desire to use BIMI for getting their logos in front of subscribers will force them to follow authentication best practices. Combined, all of these authentication methods will make for more reliable deliverability and a better reputation overall.
While it’s still on you to build subscriber trust through providing value in your email campaigns, BIMI will allow you to build the foundational trust needed to hit the inbox.
WHAT DO YOU THINK?
BIMI is still in its infancy. While only one major email provider supports it, it’s an interesting new standard that has the industry talking.
