BIMI

What is BIMI (Brand Indicators for Message Identification)?

Last Update: July 28, 2025

Enter BIMI, or Brand Indicators for Message Identification. It’s an emerging standard designed to boost email security and brand visibility right in the inbox. If you’re a web creator, especially one working with WooCommerce stores, understanding BIMI can open up new ways to deliver value.

Understanding the Email Security Landscape

Before we dive deep into BIMI, let’s talk a little about why email authentication is so important. You’ve probably heard of SPF, DKIM, and DMARC. These are the workhorses of email security, helping to verify that an email is actually from who it says it’s from.

  • SPF (Sender Policy Framework): Think of SPF as a guest list for your domain’s email. It specifies which mail servers are authorized to send email on behalf of your domain.
  • DKIM (DomainKeys Identified Mail): DKIM adds a digital signature to your emails. This signature is like a tamper-proof seal, verifying that the email content hasn’t been altered in transit.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC builds on SPF and DKIM. It tells receiving mail servers what to do if an email fails SPF or DKIM checks (like reject it or send it to quarantine). It also provides reports, so you can see who’s sending email from your domain.

These three are the bedrock of email authentication. They work behind the scenes to protect domain reputations and combat phishing. BIMI doesn’t replace them; instead, it adds a powerful visual layer on top of this foundation, particularly DMARC.

What Exactly is BIMI?

So, what’s the big deal with BIMI? Let’s break it down.

Defining BIMI

BIMI (Brand Indicators for Message Identification) is an email specification that allows brands to display their official logos next to authenticated email messages in the recipient’s inbox. It’s a visual confirmation that an email is legitimate because it has passed DMARC authentication checks. Essentially, if you’ve done the work to secure your email with DMARC, BIMI offers a way to make that trust visible.

How BIMI Works – The Technical Nitty-Gritty (Simplified)

Alright, let’s walk through how BIMI actually does its thing, without getting too lost in the weeds. As a web creator, you’re used to dealing with DNS records, and BIMI fits right into that world.

Here’s a simplified step-by-step:

  1. Email is Sent: Your client’s mail server sends an email.
  2. DMARC Authentication Check: The receiving mail server (like Gmail or Yahoo) checks for DMARC authentication. For BIMI to work, the domain sending the email must have a DMARC policy of p=quarantine or p=reject. A policy of p=none (which is just for monitoring) isn’t enough.
  3. BIMI DNS Record Lookup: If the DMARC check passes (meaning the email is verified as legitimate under the DMARC policy), the receiving server then looks for a BIMI DNS record at the sender’s domain. This is a specific type of TXT record, much like your SPF or DMARC records.
  4. Logo Location: This BIMI DNS record contains a URL pointing to the brand’s logo. This logo needs to be in a specific format: SVG (Scalable Vector Graphics) Tiny P/S.
  5. VMC Check (Often Required): Many major mailbox providers, like Gmail, also require a Verified Mark Certificate (VMC). The BIMI record can also contain a URL pointing to this VMC. The VMC is a digital certificate that proves the organization has the legal right to use the logo (i.e., it’s a registered trademark).
  6. Logo Display: If all these checks pass – DMARC alignment at enforcement, a valid BIMI record, the correct logo format, and (where required) a valid VMC – the email client can then display the brand’s logo next to the email message in the inbox.

It sounds like a few hoops to jump through, and it is. But the payoff is a visually authenticated email, which can be a big trust signal for recipients.

The Key Components of BIMI Implementation

Let’s recap the essential pieces you’ll need to get BIMI up and running for a client:

  • DMARC Enforcement: This is non-negotiable. The domain must have a DMARC policy of p=quarantine or p=reject applied to 100% of its emails. This shows you’re serious about preventing unauthenticated email from your domain.
  • SVG Logo: The logo itself has very specific requirements.
  • Format: SVG Tiny P/S (Portable/Secure). This is a restricted version of SVG.
  • Square: It must be a 1:1 aspect ratio.
  • Clear Background: No transparency; it should have a solid background color.
  • Hosted Securely: The SVG file must be accessible via HTTPS.
  • title Element: The SVG code needs a <title> element for accessibility.
  • DNS Record: You’ll need to publish a BIMI assertion record in the domain’s DNS. The syntax typically looks like this: default._bimi.yourdomain.com IN TXT “v=BIMI1; l=URL_to_your_SVG_logo; a=URL_to_your_VMC_if_you_have_one;”
  • v=BIMI1: Specifies the BIMI version.
  • l=: The direct URL to the SVG logo file.
  • a=: (Optional, but often needed for providers like Gmail) The direct URL to your VMC file.
  • Verified Mark Certificate (VMC):
  • What it is: A VMC is a digital certificate, issued by a recognized Certificate Authority (CA), that verifies your organization’s ownership and legal trademark of the logo you want to display.
  • Why it matters: Major providers like Gmail and Apple Mail require a VMC to display the BIMI logo. Without it, your logo likely won’t show up in these inboxes, even if everything else is correct.
  • The Catch: Getting a VMC involves a cost (often $1000-$1500 USD per year per logo) and a verification process that includes proving your logo is a registered trademark. This can be a hurdle for some businesses. Some CAs like DigiCert also offer Common Mark Certificates (CMCs) which might have slightly different requirements or display outcomes (e.g., logo display without a verified checkmark in some clients).

Section Summary: BIMI lets authenticated emails display a brand logo in the inbox. It relies on a strong DMARC policy, a specially formatted SVG logo, a specific DNS record, and often, a VMC to prove trademark ownership.

Getting Started with BIMI: A Practical Guide for Web Creators

So, you’re ready to explore implementing BIMI for a client. What’s the game plan? It’s a methodical process, and as a web professional, you’re well-equipped to guide your clients through it.

Step 1: Assess Current Email Authentication

Before you even think about logos, you need to know where your client stands with existing email authentication.

  • Check SPF, DKIM, and DMARC: Are these records in place? Are they correctly configured? Many online tools (like MxToolbox, DMARC Analyzer, etc.) can help you look up and validate these records for any domain.
  • DMARC Policy: What is the current DMARC policy? Is it p=none, p=quarantine, or p=reject? Remember, BIMI needs p=quarantine or p=reject at 100%.

Step 2: Achieve DMARC Enforcement

This is often the most challenging and time-consuming part of the process. You can’t just flip a switch to p=reject without potentially blocking legitimate emails.

  • Start with p=none: If they don’t have DMARC, start with a p=none policy. This allows you to monitor email traffic via DMARC reports (RUA reports) without affecting email delivery.
  • Analyze Reports: Carefully analyze these reports to identify all legitimate sending sources. This includes their primary mail servers, third-party services (like email marketing platforms, CRMs, helpdesks, etc.).
  • Align Sources: Ensure all legitimate sources are correctly authenticating with SPF and/or DKIM and that they align with the main domain.
  • Gradual Rollout: Gradually move to p=quarantine (e.g., for a small percentage of emails, then increase) and then, ideally, to p=reject. This requires careful monitoring and adjustment to avoid disrupting legitimate email flow.
  • Challenge: This phase can take weeks or even months. It demands patience and attention to detail. Communicating this timeline to your client is crucial.

Step 3: Prepare Your BIMI Logo

Once DMARC is at enforcement, you can focus on the logo.

  • Format: SVG Tiny P/S (Portable/Secure). This is a specific subset of SVG. Standard SVG files from design software might need conversion or modification. Some sources mention SVG Tiny 1.2, then needing modification to ensure it’s “PS” (Portable/Secure).
  • Specifications:
  • Square (1:1 aspect ratio).
  • Solid background color (no transparency).
  • Keep it simple and clearly recognizable, even at small sizes.
  • Include a <title> element within the SVG code with a brief description of the logo or company name.
  • Hosting: Upload the final SVG file to a publicly accessible web server using HTTPS. The URL must be stable.
  • Tools & Validation: There are scripts and tools available (some from the BIMI Group or CAs) to help convert and validate your SVG file for BIMI compliance.
  • Challenge: Getting the SVG format exactly right can be fiddly. Test it thoroughly.

Step 4: Obtain a Verified Mark Certificate (VMC) – (If Applicable/Recommended)

For many clients, especially those wanting their logo to show in Gmail or Apple Mail, a VMC is essential.

  • Trademark Requirement: The logo must be a registered trademark with a recognized intellectual property office. If it’s not, your client will need to go through the trademark registration process first, which can take months.
  • Choose a Certificate Authority (CA): Only a few CAs are currently authorized to issue VMCs. DigiCert and Entrust are the main ones.
  • Application & Validation: The CA will have an application process. They will verify:
  • The organization’s identity.
  • The trademark registration of the logo.
  • The individual applying has authority. This often involves documentation and can include verification calls.
  • Cost: VMCs typically cost around $1,200 – $1,500 USD per year, per logo. This needs to be factored into the client’s budget.
  • Receive the VMC: Once approved, you’ll receive the VMC, usually as a PEM file. This file also needs to be hosted on a publicly accessible HTTPS server.
  • Challenge: The trademark requirement and the cost are significant barriers for some businesses. The process can also take time.

Step 5: Publish Your BIMI DNS Record

With DMARC in place, your SVG logo ready, and your VMC (if using one) hosted, it’s time to publish the BIMI record.

  • Syntax: As mentioned earlier: default._bimi.yourdomain.com. IN TXT “v=BIMI1; l=https://your-cdn.com/logo.svg; a=https://your-cdn.com/vmc.pem;”
  • Replace yourdomain.com with the client’s domain.
  • Replace the l= URL with the actual URL to the SVG logo.
  • Replace the a= URL with the actual URL to the VMC .pem file (if you have one; if not, you might omit the a= part, but check provider requirements).
  • Where to Add: Add this TXT record to your client’s DNS settings, similar to how you added SPF, DKIM, or DMARC records.
  • Propagation: Allow time for DNS propagation (usually a few hours, but can take up to 48).
  • Validation Tools: Use online BIMI record checkers to ensure the syntax is correct and the URLs are accessible. Many CAs and email security vendors offer these.

Step 6: Test and Monitor

After all that hard work, you need to see if it’s working!

  • Send Test Emails: Send emails from the configured domain to inboxes at providers that support BIMI (e.g., Gmail, Yahoo, Apple Mail, Fastmail). Check if the logo appears.
  • Provider Support: Keep in mind that mailbox provider support for BIMI is still evolving. Not every email client will show the logo, and some might have their own additional criteria. Microsoft Outlook, for instance, does not currently support BIMI.
  • Currently Supporting (list may evolve): Apple Mail, Gmail, Yahoo Mail, Fastmail, La Poste, Onet Poczta, and Zone are among those that support BIMI. Some providers like Gmail require VMCs for display.
  • Ongoing DMARC Monitoring: Continue to monitor DMARC reports. BIMI relies on ongoing DMARC compliance. If DMARC fails, the logo won’t show.
  • Patience: It can sometimes take a few hours or even a couple of days for logos to start appearing consistently after setup, due to caching and propagation.

Section Summary: Implementing BIMI involves a structured approach: assess authentication, enforce DMARC, prepare a compliant SVG logo, obtain a VMC if needed, publish the BIMI DNS record, and then test and monitor. Each step requires care and attention.

Challenges and Considerations with BIMI

While BIMI offers exciting benefits, it’s important to approach it with a clear understanding of the potential hurdles. This helps you set realistic expectations for your clients.

  • Not a Magic Bullet: BIMI enhances existing email authentication; it won’t solve deliverability issues without proper SPF, DKIM, and DMARC.
  • DMARC Complexity: Achieving DMARC enforcement (quarantine or reject) is a significant hurdle requiring careful setup and monitoring of all sending sources.
  • VMC Requirement, Cost, and Trademark: Widespread logo display (especially in Gmail) often needs a costly annual VMC, and the logo must be a registered trademark.
  • SVG Logo Specificity: The strict SVG Tiny P/S format requirements can be challenging to meet and must be precise for the logo to display.
  • Mailbox Provider Support Isn’t Universal: BIMI adoption varies; logos won’t appear for all recipients as not all providers support it.
  • No Absolute Guarantee of Logo Display: Even with correct setup, mailbox providers ultimately decide whether to show the BIMI logo.
  • Time Investment: BIMI implementation, including DMARC, trademarks (if needed), and VMCs, can take months.

Overcoming Complexity with a Creator’s Guidance:

Many of these challenges stem from technical complexity or procedural hurdles. This is where you, as a web creator, can provide immense value. You’re used to navigating technical systems and can translate these requirements into manageable steps for your clients. Much like how tools aim to simplify marketing tasks within a familiar workflow, you can simplify the path to BIMI.

Section Summary: Be aware of BIMI’s challenges, including DMARC complexity, VMC costs and trademark needs, SVG specifics, and inconsistent provider support. These are manageable with careful planning and expertise.

The Future of BIMI and Email Branding

BIMI is still relatively new, but it’s gaining traction. Here’s a look at what the future might hold:

  • Growing Mailbox Provider Adoption: More email providers are expected to implement support for BIMI over time. As major players like Gmail, Apple, and Yahoo lead the way, others are likely to follow to provide a consistent user experience.
  • Increased Sender Uptake: As awareness grows and the benefits become clearer, more brands will likely invest in implementing BIMI. Early adopters often see the most significant differentiation. Some reports indicate that industries like finance and e-commerce are leading BIMI adoption.
  • Potential to Become a Standard Expectation: Just as HTTPS became the standard for websites, a visually verified sender via BIMI could become a baseline expectation for users engaging with brand emails. Emails without it might eventually seem less trustworthy by comparison.
  • Integration with Broader Security Trends: BIMI aligns with the broader industry push for stronger email authentication to combat phishing and improve digital trust. Google and Yahoo, for example, have been tightening authentication requirements for bulk senders.
  • Evolving VMC Landscape: The processes and costs associated with VMCs might evolve. There could be more CAs offering them, or different types of validation emerging over time.
  • The Role of Web Creators: As this standard matures, web creators and agencies will play a crucial role in educating clients, implementing the technical requirements, and integrating BIMI into overall branding and security strategies. You’re on the front lines of helping businesses adapt to these changes.

BIMI is more than just a fleeting trend; it represents a significant step towards a more visually secure and trustworthy email ecosystem.

Section Summary: BIMI is poised for growth in provider and sender adoption, potentially becoming a standard expectation for email communication. Web creators will be key in helping businesses navigate this evolution.

How Send by Elementor Supports Your Broader Email Marketing Efforts

Securing your domain with BIMI enhances trust and visibility before an email is opened, but effective email marketing requires more. A comprehensive communication toolkit is vital to leverage this trust by optimizing email content, design, and delivery.

  • While BIMI and DMARC establish domain-level trust and deliverability, dedicated tools streamline the creation, automation, and management of email campaigns. Think of it this way: BIMI ensures your client’s emails are seen as trustworthy; the content within then drives engagement.
  • Platforms offering an intuitive drag-and-drop email builder empower users to create professional, responsive emails without coding expertise. Pre-designed, best-practice-based templates further accelerate campaign development.
  • Effective targeting is achieved through audience segmentation based on factors like behavior and purchase history, ensuring relevant messaging. Automation capabilities, such as for abandoned carts or welcome sequences, nurture customer relationships and drive consistent sales with minimal ongoing effort.
  • Efficient contact management, possibly through WooCommerce or website form integration, coupled with real-time in-dashboard analytics, provides a clear view of campaign performance and ROI for clients.

By integrating robust domain authentication (DMARC, the basis for BIMI) with a user-friendly communication toolkit, you equip clients to safeguard their brand while actively increasing sales and customer loyalty. This holistic approach helps them achieve their business objectives, potentially fostering stronger, longer-term client partnerships and recurring revenue opportunities for you.

Conclusion: Is BIMI Worth It for Your Clients?

For businesses prioritizing email communication and brand reputation, BIMI presents a valuable investment. Its core advantages—enhanced brand recognition, increased trust, and potential engagement boost—offer compelling reasons for adoption.
