BIMI: logo authentication for emails

Five things you need to know about BIMI

BIMI: logo authentication for emails

BIMI puts your logo in recipients’ inboxes.
Great for marketing, even better for email authentication.

Using BIMI, or Brand Indicators for Message Identification, enables you to display your brand logo alongside the subject line of all the emails your organization sends.
As well as making your brand stand out, BIMI means your emails are less likely to wind up in spam folders, and fraudsters will find spoofing much harder. This is because it can only be adopted by brands and organizations that have implemented DMARC (and SPF and DKIM policies). If you don’t have DMARC in place, you can’t authenticate your domain, and BIMI won’t be possible.
While the visible branding benefit is obvious, the real aim of BIMI is to drive important improvements in email security standards worldwide. When your emails are authenticated through BIMI, recipients can have confidence that emails sent from your domain are genuine.
BIMI is still relatively new, but the recent addition of CMC (see below) will make it increasingly mainstream, and the number of email providers supporting this important change is growing all the time. 

Here’s what you need to know about BIMI.

1. NEW: With CMC, any company can now implement BIMI

When BIMI first launched, it could only be used by companies with trademarked logos. In September 2024, BIMI announced that Google will be officially supporting the use of Common Mark Certificates (CMC) in Gmail. This means BIMI can be used by businesses with non-trademarked logos, making it accessible to organizations of all sizes.

2. NEW: Android and iOS users will now see BIMI checkmarks

If their email client supports BIMI, Android and iOS (16 and later) mobile users will see logos for BIMI senders with registered trademarks.

3. Why is BIMI important for email security?

BIMI is helping to drive the adoption of DMARC email authentication. If you want to use BIMI, you need to have DMARC (and SPF and DKIM policies) in place.

4. Who supports BIMI?

Currently, BIMI is supported by AOL, Apple, Cloudmark, Fastmail, Google, LaPoste, MailChimp, Twilio, Yahoo, Zoho and more.

5. Be one step ahead of your marketing team

Make sure BIMI is on your roadmap before your marketers come and ask for it! Because once they start seeing competitors’ logos appearing in in-boxes, they’ll be asking how it’s done and wanting the same – show you’re ahead of the game and already on the case.
