Why marketers should care about BIMI

Bring your brand into the inbox

You invest in a recognisable website, consistent creative and a carefully designed email template. Before a customer sees that template, they encounter the sender identity in their inbox. That is a brand touchpoint worth paying attention to.

BIMI stands for Brand Indicators for Message Identification. It lets a brand publish a preferred logo for supporting email services to display alongside authenticated messages. Some inboxes show it in the message list, creating an opportunity for recognition before the email is opened; placement varies by provider and application.

For marketing, the useful question is simple: does the identity beside our email look like the brand our customers already know? A familiar symbol can give them another cue when scanning for a newsletter, receipt or account message. Think of this as extending your visual identity into another part of the customer experience.

Connect campaigns to the rest of the customer journey

A customer may receive a welcome email, an offer, a purchase confirmation and a service update from different systems. Marketing often owns the campaign creative, while the other messages belong to commerce, product or support teams.

A BIMI project is a useful reason to review that whole journey. Which brand should each message represent? Are the sender names understandable? Is the artwork current? Are old systems still using a forgotten sending domain?

Map those messages before choosing the rollout scope. Each sending domain and platform needs the relevant setup and testing. Once the intended identity is documented, include it in your brand guidelines and rebrand checklist so the inbox stays part of routine brand management.

Give customers a clearer identity signal

The logo is connected to email authentication and, where required, evidence of rights to the mark. That gives marketers something more useful to communicate than a cosmetic change: the organisation has connected its sending identity with its approved branding.

Google’s BIMI documentation distinguishes two outcomes. Gmail accepts a Verified Mark Certificate (VMC) or a Common Mark Certificate (CMC) for BIMI, while its verified checkmark is associated with a VMC. Decide whether your objective is logo display, that checkmark, or both before choosing a certificate route.

Describe the result precisely in customer communications. A logo does not certify an email’s claims or make every link safe. Customer education should still encourage care with unexpected requests. The marketing opportunity is a recognisable, authenticated identity; any increase in customer confidence is an outcome to assess.

Marketing should help own the brief

Marketers do not need to become DNS administrators to contribute. Their job is to explain the desired customer experience and make the brand decisions that a technical team cannot make alone.

Name one person to coordinate the work and one to own maintenance after launch. Include certificate renewal and logo changes in the handover. A working launch needs a sustainable owner as much as it needs approved artwork.

Prioritise the inboxes your audience actually uses

BIMI deserves a closer look when email is an important customer channel, your logo is stable and recognisable, and a meaningful share of your audience uses inboxes where you can verify the intended display.

Check current mailbox support and build a small test set around your recipients. A list of email domains is only an estimate of provider mix: business domains do not always reveal who hosts their mail. Avoid turning that estimate into a promise that every customer will see the logo.

Allow for certificate costs where required, artwork preparation, authentication work, hosting and renewal. If your sending setup is fragmented or a rebrand is imminent, resolve those dependencies first. The budget checklist helps turn interest into a realistic scope.

Measure recognition and results separately

Start with evidence that the intended logo appears in the agreed test inboxes. Then ask whether customers recognise your messages more easily. A focused customer study can address that question more directly than a campaign dashboard alone.

For commercial outcomes, choose measures that fit the campaign: meaningful clicks, completed purchases, registrations or another relevant action. Keep the offer, audience and sending schedule as comparable as practical, and record other changes that could explain the result.

Raw open rates need particular care. Apple’s Mail Privacy Protection can prevent senders from knowing whether a message was opened. A before-and-after increase also does not establish that BIMI caused it. Use the measurement guide to separate display checks from campaign analysis.

BIMI does not guarantee inbox placement or a fixed uplift in engagement. Permission, relevant content, sender reputation and a good customer experience still need their own attention.

Start with a one-page marketing brief

Bring a concrete proposal to your email and security teams:

• Objective: which customer experience should improve?
• Scope: which brand, sending domains and message types come first?
• Audience: which inboxes need to be tested?
• Identity: which logo is approved, and is a rebrand planned?
• Success: how will you check display, recognition and business outcomes?
• Ownership: who approves the budget and maintains the setup?

A useful starting objective might be: “Make our newsletter and order confirmations easier to recognise in the inboxes our customers use.” That gives the team a clear reason to investigate BIMI and a practical basis for deciding whether to proceed.
