Summary
BIMI (Brand Indicators for Message Identification) promises enhanced brand visibility and trust by displaying a company's logo next to their emails in the inbox. Despite its clear benefits, widespread BIMI adoption has been notably slow, and its implementation presents several challenges for organizations. These challenges span technical complexities, security concerns, the financial burden of Verified Mark Certificates (VMCs), and the prerequisite of robust email authentication protocols like DMARC.
Key findings
- Slow adoption: Despite being an established standard, BIMI's uptake has been gradual, with many organizations still in a 'wait and see' mode or encountering significant hurdles during implementation. Analysis indicates high error rates for those attempting implementation.
- DMARC prerequisite: A fundamental requirement for BIMI is a DMARC policy set to p=quarantine or p=reject, meaning senders must first fully enforce their email authentication. This is a significant barrier for many who are still at p=none. Learn how to implement DMARC p=reject safely.
- VMC requirement: The need for a Verified Mark Certificate (VMC) to display a trademarked logo introduces a cost and an additional layer of administrative complexity, requiring validation from a Certificate Authority.
- Technical complexity: Configuring the necessary DNS TXT records and ensuring the SVG logo file adheres to strict specifications often requires specialized technical expertise.
- Fraud prevention: A key challenge for BIMI, and a reason for its deliberate rollout, is ensuring that logos cannot be easily appropriated by malicious actors for phishing or impersonation, which VMCs and DMARC enforcement aim to address.
Key considerations
- Phased DMARC deployment: Organizations should incrementally move their DMARC policy from p=none to p=quarantine and then p=reject to avoid unintended blocking of legitimate emails, a critical step before BIMI.
- VMC cost-benefit analysis: Evaluate the financial investment in a VMC against the perceived brand trust and visibility benefits, especially for smaller businesses.
- Technical expertise: Ensure your team or external partners have the necessary knowledge for DNS management, SVG formatting, and email authentication (including SPF, DKIM, and DMARC) to implement BIMI correctly. A simple guide to DMARC, SPF, and DKIM can be a good starting point.
- Trademark registration: Only logos with registered trademarks are eligible for BIMI with a VMC, adding a legal prerequisite for brands seeking this visual authentication.
- Evolving standards: Be aware that the BIMI landscape, including support from mailbox providers and certificate types, may continue to evolve.
What email marketers say
Email marketers often express both enthusiasm for BIMI's potential and frustration with its slow adoption and perceived complexities. While the promise of enhanced brand visibility and trust is appealing, the practical hurdles, including technical setup, cost, and the prerequisite of a strong DMARC policy, often overshadow the immediate benefits, leading to a cautious approach.
Key opinions
- Simplicity vs. reality: Marketers perceive BIMI implementation as conceptually simple (a DNS TXT record pointing to logos) but find it more complex in practice due to the VMC requirement and specific file formats.
- Cost concerns: The cost of obtaining a Verified Mark Certificate (VMC) is a significant barrier, especially for smaller businesses, making the ROI seem questionable for some.
- Brand impersonation fears: There are concerns about how BIMI prevents unauthorized use of brand logos, highlighting the need for robust validation processes (e.g., VMCs) to maintain trust and prevent fraud.
- DMARC policy necessity: Many marketers recognize that a DMARC policy of p=reject or p=quarantine is a prerequisite, which can be a challenging step for organizations to achieve due to fear of legitimate email blocking.
- Gmail annotations alternative: Some marketers speculate that Gmail Annotations might become the preferred method for displaying brand information, potentially sidelining BIMI or leading to its deprecation by major email providers.
Key considerations
- Aligning expectations: Marketers should understand that BIMI is not a quick fix for deliverability but a brand-enhancement tool built on strong authentication. Understanding BIMI's impact on email engagement metrics is crucial.
- Internal resource allocation: Successful BIMI implementation often requires collaboration between marketing, IT, and legal teams, demanding significant internal coordination and technical know-how.
- Monitoring progress: Regularly monitor your email authentication status, including DMARC reports, to ensure proper alignment before considering BIMI. Tools like Google Postmaster Tools can be helpful.
- VMC provider selection: Choose a reputable VMC provider that simplifies the certificate acquisition and renewal process. This is a key step towards displaying your logo and enhancing brand trust.
Marketer view
Email marketer from Email Geeks notes a lack of response after applying for BIMI, suggesting a slow or unclear process. They express concern that if Gmail Annotations become mainstream, BIMI might be deprecated by Google and Microsoft. This sentiment highlights the uncertainty surrounding BIMI's long-term viability in a rapidly evolving email ecosystem. The perception that BIMI could be superseded by proprietary features like Gmail Annotations can deter early adoption.
Marketer view
Marketer from Email Geeks shares a similar experience with slow BIMI progress, reinforcing the sentiment that adoption has been frustratingly slow or stagnant. This widespread experience among email professionals indicates systemic issues rather than isolated incidents. Such shared frustrations can lead to a collective hesitation within the industry to invest further resources into BIMI until clearer pathways and benefits emerge.
What the experts say
Email deliverability experts highlight that BIMI's slow adoption is less about the technical simplicity of a DNS record and more about the stringent prerequisites and underlying complexities it mandates. They emphasize the critical role of strong authentication, VMCs, and the evolving ecosystem in the pace of its rollout. Experts often draw parallels to the early days of DMARC, where initial adoption was also slow until major mailbox providers exerted pressure.
Key opinions
- DMARC enforcement is paramount: The single biggest barrier to BIMI adoption is the requirement for a DMARC policy at an enforcement level (p=quarantine or p=reject). Many organizations are still at p=none or lack proper DMARC alignment.
- VMC cost and complexity: The process of obtaining and renewing a Verified Mark Certificate from an accredited Certificate Authority adds financial and administrative burden, which can be prohibitive for many companies.
- Limited perceived ROI: For some, the benefits of displaying a logo are not compelling enough to justify the significant effort and investment required, especially if their brand is already well-recognized.
- Ecosystem maturity: The entire BIMI ecosystem, including support from various email clients and the stability of Certificate Authorities, needs further maturation for seamless adoption.
- Technical subtleties of SVG: The strict technical requirements for the SVG logo file (e.g., SVG Tiny PS profile) can pose unexpected challenges for design teams.
Key considerations
- Prioritize DMARC: Organizations should first focus on achieving a robust DMARC implementation with an enforcement policy. Understanding why DMARC verification fails is critical.
- Assess readiness: Before embarking on BIMI, assess your organization's technical capabilities, legal readiness (trademark), and commitment to managing the ongoing requirements.
- Stay informed: Keep abreast of updates from BIMI working groups, Certificate Authorities, and major mailbox providers, as the standard and its implementation may evolve. Technical difficulties can arise.
- Address DMARC policy issues: For organizations experiencing DMARC policy not enabled warnings, resolving these is a prerequisite for BIMI implementation.
Expert view
Deliverability Expert from SpamResource emphasizes that the primary obstacle to widespread BIMI adoption is the requirement for a DMARC policy at enforcement (p=quarantine or p=reject). Many organizations are still at p=none due to fear of legitimate mail blocking, a critical prerequisite that slows BIMI's rollout. This highlights a common challenge where companies prioritize not losing any mail over enhanced brand security, creating a bottleneck for new authentication standards that build upon DMARC.
Expert view
Email Authentication Specialist from Word to the Wise suggests that the cost and complexity associated with obtaining and maintaining a Verified Mark Certificate (VMC) from an accredited Certificate Authority presents a significant barrier. This technical and financial hurdle disproportionately affects smaller businesses and those without dedicated security teams. Such specialized certification processes add a layer of bureaucracy and expense that many organizations are not prepared for, slowing down their ability to adopt BIMI even if their DMARC is in order.
What the documentation says
Official documentation and research reports underscore the technical requirements and security considerations that underpin BIMI, explaining why its adoption curve is deliberately paced. They detail the necessity of a strong email authentication foundation (DMARC enforcement) and the verification process involving Verified Mark Certificates to ensure brand authenticity and prevent abuse.
Key findings
- DMARC enforcement is mandatory: BIMI requires the sending domain to have a DMARC record published with a policy set to p=quarantine or p=reject, ensuring the domain is protected against impersonation before a logo is displayed.
- VMC verification: To display a logo, a Verified Mark Certificate (VMC) from a trusted Certificate Authority is necessary. This certificate validates that the organization owns the trademark for the logo being used. A guide to BIMI accredited certificate providers can assist in this process.
- Specific SVG requirements: The logo image must be in SVG (Scalable Vector Graphics) format and adhere to strict specifications, including being an SVG Tiny PS profile, to ensure proper rendering and security.
- DNS TXT record: The BIMI record is published in DNS as a TXT record, containing the version, logo URL, and VMC URL, which mail servers check for logo display.
- High implementation error rates: Despite a clear standard, errors in BIMI implementation remain common, indicating the intricacy of correctly configuring all required elements.
Key considerations
- Thorough pre-checks: Before attempting BIMI, ensure your SPF, DKIM, and DMARC records are correctly configured and your DMARC policy is at an enforcement level. Validating your BIMI SVG and certificate is also crucial.
- Adherence to specifications: Pay close attention to the detailed technical specifications for SVG logos and DNS records to avoid common implementation errors.
- Trademark legalities: Ensure your logo is a registered trademark in the relevant jurisdictions, as this is a prerequisite for VMC issuance.
- Leverage documentation: Consult official BIMI Group specifications and guidelines provided by organizations like AWS for precise implementation steps.
Technical article
Uriports Blog, a research publication, highlights that while BIMI adoption is steadily increasing, error rates in implementation remain high. This suggests that the complexity of correctly configuring all components, including DNS records and VMCs, is a significant hurdle for organizations. The persistent high error rates indicate that the process is not as straightforward as it might seem, leading to frustration and extended deployment times for many brands attempting to implement BIMI.
Technical article
