1 August, 2024 7 Mins Read

Feeling overwhelmed by spam and unsure which emails to trust? There’s a new solution in the block, and it’s here to help your inbox.

BIMI (Brand Indicators for Message Identification) is here to transform email communication by adding a layer of visual verification. Imagine seeing your favorite brand’s logo displayed prominently next to their emails – no more guessing games about legitimacy! But BIMI’s benefits go beyond brand recognition. Read this blog to know more. 

Understanding BIMI

BIMI builds upon the foundation laid by existing email authentication standards like SPF, DKIM, and DMARC, providing an additional layer of visual verification. By displaying sender logos, BIMI offers recipients a tangible and recognizable symbol of authenticity, making it easier to discern legitimate emails from fraudulent ones. This visual cue not only increases brand visibility but also reinforces the credibility of authenticated emails in recipients’ minds. As a result, BIMI holds the potential to revolutionize email marketing by creating a more secure and trustworthy communication channel for businesses and consumers alike.

BIMI encourages greater collaboration between email senders, receivers, and service providers, fostering a more cohesive and standardized approach to email authentication. As BIMI adoption grows, it has the potential to become a widely accepted industry standard, further solidifying its role in email security and brand recognition. As businesses strive to build stronger relationships with their customers, BIMI offers a promising solution to enhance the authenticity and effectiveness of email communications.

How BIMI Works

Understanding how BIMI operates is key to unlocking its full potential. Let’s look into the technical aspects, exploring the essential components that make BIMI tick:

Email Authentication: Before BIMI can display a sender’s logo, the email must pass authentication checks such as SPF, DKIM, and DMARC, which are industry-standard protocols endorsed by major email service providers. These protocols collectively establish a foundation of trust by verifying the sender’s identity and ensuring message integrity, contributing to a safer email ecosystem.

SVG-Based Logo: Once authenticated, BIMI utilizes Scalable Vector Graphics (SVG) to display the sender’s logo alongside the email in recipients’ inboxes. This format allows for flexibility in logo design and size, ensuring that the logo appears crisp and clear on all devices, including desktops, mobile phones, and tablets.

DNS Record: To enable BIMI, the sender must publish a BIMI record in their DNS (Domain Name System), a fundamental component of the internet’s infrastructure. This record not only specifies the location of the SVG file containing the sender’s logo but also includes additional metadata, such as the logo’s dimensions and aspect ratio, to optimize its display across different email clients.

Receiver Support: While BIMI offers significant benefits, its effectiveness relies on widespread support from email clients and mailbox providers. While major players like Gmail and Yahoo fully support BIMI, smaller providers may be slower to adopt the standard. But as BIMI gains traction and proves its value in enhancing brand recognition and security, broader adoption among email service providers is anticipated, driving further improvements in email authentication and deliverability.

Impact on Email Deliverability

While BIMI’s role in boosting brand recognition is undeniable, its true power lies in its ability to significantly impact email deliverability. Here’s how displaying your logo alongside authenticated emails goes beyond aesthetics, fostering trust, mitigating phishing risks, and ultimately driving higher engagement.

Enhanced Brand Visibility: BIMI provides a visual cue of authenticity by displaying the sender’s logo alongside authenticated emails. This not only increases brand recognition but also helps recipients identify legitimate emails amidst a sea of spam and phishing attempts. A consistent brand presence in emails reinforces brand identity and fosters brand loyalty among recipients.

Improved Trust: By associating a recognizable logo with authenticated emails, BIMI helps build trust between senders and recipients. When recipients see a familiar logo, they are more likely to engage with the email, resulting in higher open and click-through rates. Moreover, the presence of a verified logo instills confidence in recipients, assuring them of the email’s legitimacy and reducing the likelihood of it being marked as spam.

Phishing Mitigation: One of the primary objectives of BIMI is to combat phishing attacks by making it harder for malicious actors to impersonate legitimate brands. By displaying logos only for authenticated emails, BIMI provides an additional layer of security, reducing the risk of phishing scams. The visual indicator of a trusted brand logo helps recipients discern between genuine emails and fraudulent ones, mitigating the success of phishing attempts.

Email Engagement: Studies have shown that emails with visual elements, such as logos, tend to have higher engagement rates. BIMI capitalizes on this by adding a visual element that captures recipients’ attention and encourages them to interact with the email content. The presence of a logo reinforces brand recall, prompting recipients to not only open the email but also to actively engage with its content, leading to improved conversion rates and customer retention.

Implementing BIMI

Implementing BIMI is a strategic process that requires attention to detail and adherence to best practices to fully leverage its benefits. Here’s a comprehensive guide to implementing BIMI effectively:

  1. Ensure Email Authentication: Before enabling BIMI, it’s imperative to ensure that your email authentication protocols, including SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance), are correctly configured and enforced. These protocols verify the authenticity of your emails and prevent spoofing, laying the foundation for BIMI to display your logo alongside authenticated emails.
    • SPF: SPF allows email servers to verify that incoming mail from a domain comes from an IP address authorized by that domain’s administrators.
    • DKIM: DKIM adds a digital signature to outgoing emails, allowing recipients’ servers to verify that the email content hasn’t been altered during transit.
    • DMARC: DMARC builds upon SPF and DKIM, providing domain owners with visibility into how their emails are being handled and enabling them to set policies for how unauthenticated emails should be handled.
  2. Create a High-Quality Logo: The success of BIMI heavily relies on the quality and recognizability of your logo. Invest in creating a high-quality SVG (Scalable Vector Graphics) logo that accurately represents your brand. Your logo should be visually appealing, scalable to different sizes without loss of quality, and instantly recognizable by your audience. Work with designers to ensure that your logo aligns with your brand identity and effectively communicates your message.
  3. Publish BIMI DNS Record: To enable BIMI, you need to publish a BIMI record in your DNS (Domain Name System). This record specifies the location of your logo file and includes the necessary cryptographic hash for verification. Here’s how to publish your BIMI DNS record:
    • Generate BIMI Record: Use a BIMI record generator to create your BIMI record. This record typically includes the location of your SVG logo file (e.g., https://example.com/logo.svg) and the cryptographic hash (SHA-256) of the logo file.
    • Add Record to DNS: Once generated, add the BIMI record to your DNS configuration. This involves accessing your DNS management dashboard provided by your domain registrar or hosting provider and adding a TXT record with the BIMI information.
  4. Monitor Performance: After implementing BIMI, it’s essential to monitor its performance to gauge its impact on email engagement and deliverability. Keep track of key performance metrics, including logo impressions, click-through rates, and overall email deliverability. Analyze the data regularly to identify trends, optimize your BIMI implementation, and make informed decisions about your email marketing strategy. Stay updated on industry developments and best practices to ensure that your BIMI implementation remains effective in the long term. Regular monitoring and adjustment are essential to maximize the benefits of BIMI and enhance your email marketing efforts.

BIMI represents a significant advancement in email authentication and brand recognition. By displaying sender logos alongside authenticated emails, BIMI enhances brand visibility, fosters trust, and mitigates phishing risks. While its impact on email deliverability is promising, widespread adoption and email client support are essential for maximizing its benefits. By understanding and implementing BIMI effectively, marketers can elevate their email marketing strategies and cultivate stronger relationships with their audience.
