Where are the primary sources for BIMI adoption statistics?

While there isn't one single official repository for all BIMI adoption statistics, several reputable sources provide valuable data. Key places to check include BIMI Radar (bimiradar.com) and DMARC.org. These platforms actively monitor DNS records and aggregate data to provide insights into global BIMI adoption rates, typically updated periodically.

What is the current status of BIMI adoption among email senders?

Based on recent reports, BIMI adoption is steadily increasing but is still relatively low compared to broader email authentication standards like DMARC. Many thousands of unique and valid BIMI records have been observed, with growth reported year-over-year. However, a significant portion of domains with BIMI records may still have configuration errors.

What are the main prerequisites for a domain to adopt BIMI?

The primary requirement for BIMI is a DMARC policy set to enforcement (p=quarantine or p=reject). Without an enforcing DMARC policy, your BIMI logo will not display. Additionally, many major mailbox providers require a Verified Mark Certificate (VMC) to prove ownership of the logo and trademark, adding another layer of complexity and cost.

How does BIMI benefit email senders, and does it impact deliverability?

BIMI enhances brand visibility by displaying your logo directly in the recipient's inbox, which can improve email engagement (e.g., open rates). It also boosts trust by visually confirming your legitimacy, which is vital in combating phishing. However, it requires a robust DMARC implementation, meaning it primarily leverages existing authentication rather than directly improving deliverability on its own.

Do all email clients and providers support BIMI?

While major providers like Google (Gmail) and Yahoo Mail support BIMI, not all email clients or mailbox providers do. Even among those that do, some may require a VMC for the logo to appear. It is essential to check the specific requirements of the mailbox providers your audience uses.

Where can I find statistics on BIMI adoption by email senders? - Technical - Email deliverability - Knowledge base

As email security standards continue to evolve, Brand Indicators for Message Identification (BIMI) has emerged as a significant development, promising enhanced brand visibility and trust. Many email senders are keen to understand its widespread acceptance and how their adoption compares to industry trends. Finding reliable statistics on BIMI adoption can be a crucial step in strategizing your email authentication efforts.

BIMI allows organizations to display their brand logo next to their authenticated email messages in the recipient's inbox. This visual cue helps recipients quickly identify legitimate senders, which can reduce the effectiveness of phishing attacks and improve engagement. However, BIMI relies on strong email authentication, primarily DMARC enforcement, to ensure the displayed logo is tied to a verified sender.

Understanding the current landscape of BIMI adoption helps you assess its growing importance and potential impact on your email program. It provides insight into how many other senders are leveraging this standard and which industries are leading the charge. Let's explore where you can find these valuable statistics.

Tracking BIMI adoption rates

Several authoritative sources track BIMI adoption by monitoring DNS records for BIMI entries across millions of domains. These sources compile their data from various methodologies, including scanning the internet for specific DNS records or leveraging DMARC aggregate reports from mailbox providers. The data often includes information on the number of domains publishing BIMI records, the presence of Verified Mark Certificates (VMCs), and the quality of BIMI implementations.

One of the most comprehensive resources for tracking BIMI adoption is BIMI Radar. This platform provides global adoption trends for BIMI and related technologies, indicating BIMI readiness based on strong email authentication. It's a useful resource for understanding the overall trajectory and growth of BIMI across various domains worldwide.

Another key source is DMARC.org, which started supplying data on DNS lookups of BIMI records in mid-2021. Their reports offer insights into the number of unique and valid BIMI records observed. These statistics are essential for getting a snapshot of how many brands have successfully implemented BIMI and maintain active records in the DNS.

Source	Reported Period	Key Statistic
DMARC.org	Mid-2024	Nearly 34,000 unique and valid BIMI records observed.
URIports	Recent analysis (2025 update)	28% growth in BIMI adoption, but 64% increase in domains with errors.
SpamResource	June 2023	14,305 of top 10 million domains published a BIMI record (~0.14%).
Agari (Fortra)	H2 2020	3.8X increase in brands adopting BIMI since April 2020.

Current state of BIMI adoption

While the numbers for BIMI adoption are growing steadily, they are still relatively small compared to broader email authentication standards like DMARC. For instance, in June 2023, only about 0.14% of the top ten million domains had published a BIMI record. This indicates that while there's momentum, BIMI is still in its early stages of widespread adoption. Part of this slower pace can be attributed to the stringent BIMI implementation requirements.

It's important to note that a significant portion of domains with BIMI records also show errors in their configuration. This highlights a gap between attempted implementation and correct setup, emphasizing the need for careful validation. Simply publishing a BIMI record isn't enough; it must be valid and correctly configured to function as intended and for your brand logo to appear. This often requires deep technical understanding of DNS records and email authentication protocols.

A key factor limiting BIMI adoption is its prerequisite: a DMARC policy set to enforcement (p=quarantine or p=reject). Many organizations still run DMARC at p=none, which means they are not yet eligible for BIMI. As of a recent analysis, only about 34% of senders using DMARC are even eligible for BIMI logos. This indicates that growing BIMI adoption heavily relies on the broader adoption of a strict DMARC policy.

BIMI relies on DMARC

To implement BIMI, your domain must have a DMARC policy set to either quarantine (p=quarantine) or reject (p=reject). A policy of p=none, while useful for monitoring, does not provide the necessary security assurance for BIMI to display your logo. This is a critical prerequisite that many organizations have not yet met.

Driving factors and hurdles in BIMI implementation

The primary drivers for BIMI adoption stem from its potential to enhance brand visibility and trust. By displaying a verified logo directly in the inbox, brands can instantly communicate legitimacy to recipients, which can lead to improved engagement metrics, such as higher open and click-through rates. Furthermore, BIMI reinforces existing email authentication, making it harder for cybercriminals to impersonate legitimate senders, thereby reducing phishing attacks.

Another significant factor is the increasing support from major email clients and providers. With

Google and

Apple (initially) rolling out support for BIMI, it has received a substantial boost. This support from large providers is crucial because it ensures that a significant portion of email recipients will actually see the BIMI logo, making the effort of implementation worthwhile for senders. We have a dedicated article explaining which email clients support BIMI.

However, hurdles remain. The requirement for a Verified Mark Certificate (VMC) for many providers adds an additional layer of complexity and cost. Obtaining a VMC involves a rigorous verification process to confirm the authenticity of the brand's logo. This process, while ensuring trust and security, can be a barrier for smaller businesses or those with limited resources. Additionally, there are still some email providers that do not support BIMI without a VMC.

Benefits of BIMI

Enhanced brand visibility: Display your logo in the inbox, making your emails stand out.
Increased trust and recognition: Recipients instantly recognize legitimate emails from your brand.
Improved email security: Drives stronger email authentication, like DMARC enforcement.
Higher engagement rates: Visual trust signals can lead to better open and click-through rates.

Challenges of BIMI

DMARC enforcement prerequisite: Requires a DMARC policy set to p=quarantine or p=reject.
Verified mark certificate (VMC): Often required, adding complexity and cost for logo verification.
Varying client support: Not all email clients currently support BIMI, limiting universal display.
Technical implementation: Requires proper DNS configuration and ongoing maintenance.

The future of BIMI: will it become an email standard?

The trajectory for BIMI suggests continued growth, especially as more mailbox providers (like

Yahoo) embrace the standard. There's a strong industry push for it to become a universal trust indicator, similar to how SSL/TLS certificates provide visual trust for websites. Just as a browser might warn you about an unsecured website, the vision for BIMI is that the absence of a verified logo might eventually signal an email of lower trustworthiness. You can learn more about if BIMI will become a standard trust indicator for email.

However, the path to universal adoption is not without its challenges. The inherent risk associated with DMARC enforcement policies, especially for smaller businesses lacking dedicated resources, poses a significant hurdle. Unlike SSL, which is relatively straightforward and low-risk to implement, DMARC enforcement requires careful monitoring of authentication failures to avoid legitimate emails being rejected or quarantined. This creates a potential gap where large enterprises might adopt BIMI, leaving smaller entities behind, potentially impacting the perceived trustworthiness of their email communications.

Despite these concerns, the security mechanisms built into BIMI, particularly the requirement for VMCs and the involvement of trademark authorities, are designed to prevent scammers from leveraging BIMI for fraudulent purposes. The verification process ensures that only legitimate brands can display their logos, making it difficult for malicious actors to create lookalike fakes or operate anonymously. As the standard matures and implementation tools improve, BIMI is poised to play an increasingly important role in the overall email ecosystem, enhancing both security and brand presence.
