14-Email Implementing BIMI for Brand Recognition

by | Feb 3, 2025 | Linux

How to Implement Brand Indicators for Message Identification (BIMI):-
BIMI (Brand Indicators for Message Identification) is an email authentication standard that displays your brand logo in email clients. This enhances brand recognition and security by reducing phishing risks. Here’s a step-by-step guide on how to implement BIMI for your domain.

Step 1: Meet the Pre-requirements:

1 Set Up a DMARC Policy Your domain must have a DMARC policy with quarantine or reject enforcement. v=DMARC1; p=reject; sp=reject; adkim=s; aspf=s; rua=mailto:[email protected]; ruf=mailto:[email protected]; rf=afrf; pct=100; ri=86400
2 Obtain a Verified Mark Certificate (VMC) Email providers like Gmail require a VMC to display your brand’s logo.

The logo must be trademarked and submitted in SVG format.
3 Prepare a Compliant Logo The logo must be in SVG Tiny 1.2 format. The “baseProfile” attribute set to “tiny-ps”
The “version” attribute set to “1.2”.
A <title> element must be included that reflects the company name, though there are no strict requirements for the content of the element.
A <desc> (i.e. the “description”) element is not required, but this should be included to support accessibility.


Self-asserted logos:- logos that are published without verification certificates and are supported by Yahoo, Fastmail, and others. BIMI works without VMC or the CMC, meaning that the entry point for BIMI is very attainable. I always recommend starting your BIMI journey with this option.

Select VMC or CMC Certificate for BIMI

Before applying for a BIMI certificate, you must decide whether you need a Verified Mark Certificate (VMC) or a Certificate Mark Certificate (CMC):
Verified Mark Certificate (VMC)
Required by most major mailbox providers like Gmail, Yahoo, and Fastmail.
Validates that your organization owns the trademarked logo displayed in recipients’ inboxes.
Issued by certificate authorities like DigiCert, GlobalSign, or Entrust.

Certificate Mark Certificate (CMC)
They are issued by certification authorities (Entrust or DigiCert) recognized by the BIMI Working Group. 
The verification process includes checking your brand’s logo and DMARC policy.
Like VMCs, CMCs involve an annual fee for issuance and maintenance.
This is a good alternative for smaller businesses that may not have trademarked their logo or for businesses making changes to their logos that have not been processed by the trademark authority yet.
At Google, a CMC is required for logo presentation, along with qualifying local reputation and volume. 
Less commonly used but an alternative for certain email ecosystems.
Some mailbox providers may not require a VMC but still follow BIMI standards.

 

Recommended: If you want your logo to be displayed in Gmail and other major providers, choose VMC.

Id Feature Verified Mark Certificate (VMC) Certificate Mark Certificate (CMC)
1 Purpose Required by major mailbox providers like Gmail, Yahoo, and Fastmail. Alternative to VMC for certain email providers.
CMCs offer a similar level of verification as VMCs.
2 BIMI Requirement Mandatory for most providers to display a logo in the inbox. Not required by all mailbox providers but can still be used with BIMI.
3 Trademark Requirement A trademarked logo is mandatory. You must have used the logo for at least 12 months before the Mark verification date on a domain you control.
 May not always require a trademarked logo.
4 Supported Providers Google/Gmail (enhanced support, blue checkmark)
Apple (Digitally certified label in message details)
au.com
Yahoo
Fastmail
Cloudmark
La Poste
Onet
ZohoMail
Zone
Zoner		 Some providers that do not enforce VMC requirements.
5 Issuing Authorities DigiCert, Entrust. Less widely available compared to VMC.
6 Cost $1,000 – $1,500 per year. Typically lower cost or no cost in some implementations.
7 Verification Process Strict validation of logo ownership and DMARC compliance. Less stringent than VMC.

Gmail now supports Common Mark Certificates (CMC), a new type of BIMI certificate being issued by Certificate Authorities (CA). CMCs allow a broader range of senders to utilize BIMI, who might not have the registered trademark required for a Verified Mark Certificate (VMC). With a CMC, the sender’s brand avatar will be displayed without the Gmail-verified checkmark.

Step 2: Choose a BIMI Certificate Provider (once your logo ready)

id Provider Features Cost (Approx.)
1 DigiCert Global CA, automated verification, supports BIMI VMCs.
in 2020 DigiCert is partnering with Valimail to help firms embrace BIMI (Brand Indicators for Message Identification), an email security standard that helps brands display a logo in their email subject lines with Verified Mark Certificates (VMCs).
 Starts at $1,499/year
2 Entrust Trusted CA for BIMI, offers compliance assistance Starts at $1,499/year (Not supported by Chrome)
3 GlobalSign (Upcoming) Expected to issue BIMI VMCs soon TBD

Important Note About Entrust:-
Google Chrome does not currently support Entrust VMCs, which affects the display of the BIMI logo in Gmail and other Google services.

Step 3: Free BIMI Tools
There are no free VMC providers, but you can check your BIMI readiness with these free tools:
BIMI Group – https://bimigroup.org/
Valimail BIMI Monitor – https://www.valimail.com
EasyDMARC BIMI Lookup Tool – https://easydmarc.com/tools/bimi-lookup.

Step 4: BIMI Support for Subdomains:-
If you manage multiple subdomains, check which providers:
DigiCert – Supports  as per below

Domain Structure Number of Logos VMC Configuration
Single domain One One
Single domain Multiple (more than one) Multiple: One VMC per logo
Multiple domains One One
Multiple subdomains One One
Multiple domains Multiple (more than one) Multiple: One VMC per logo
Multiple subdomains Multiple (more than one) Multiple: One VMC per logo

Entrust – Allows subdomain BIMI, but each subdomain needs an individual VMC.
Valimail – Offers BIMI services and may support subdomain setups upon request.

Step 5: Apply for a BIMI Certificate:-
Trademark Your Logo – Register your brand’s logo with a trademark office. The following trademark offices are approved for BIMI (Brand Indicators for Message Identification).

 

United States (US) United States Patent and Trademark Office (USPTO) https://www.uspto.gov/
Canada (CA) Canadian Intellectual Property Office https://www.ic.gc.ca/eic/site/cipointernet-internetopic.nsf/eng/home
European Union (EU) European Union Intellectual Property Office https://euipo.europa.eu/ohimportal/en
United Kingdom (GB) UK Intellectual Property Office https://www.gov.uk/government/organisations/intellectual-property-office
Germany (DE) Deutsches Patent- und Markenamt https://www.dpma.de/
Japan (JP) Japan Trademark Office https://www.jpo.go.jp/e/

South Korea (KR) Korean Intellectual Property Office https://kipo.go.kr/en
New Zealand (NZ) Intellectual Property Office of New Zealand (IPONZ) https://www.iponz.govt.nz/

Document List:-
=> Basic Business & Applicant Information

Trademark Application Form – The official form required for trademark registration.
Applicant’s Name & Address – Details of the individual or company filing for the trademark.
Business Registration Certificate – Proof that the business is legally registered.
Nationality & Legal Status – If an individual, provide a valid ID (passport, driver’s license); if a company, submit incorporation documents.

=> Logo-Related Documents

Trademarked Logo Image – A clear, high-resolution image of your logo in JPG, PNG, or PDF format.
Trademark Class & Description – A description of the products/services under the trademark.
List of Goods & Services (Nice Classification) – Specify the categories your logo applies to.
Usage Proof (if applicable) – Screenshots of website, product packaging, or marketing materials showing the logo in use.

=> Legal & Authorization Documents

Power of Attorney (if using a trademark attorney) – Required in some jurisdictions.
Declaration of Use – Sworn statement confirming actual logo usage in commerce.
Consent Letter (if needed) – Required if the logo contains a personal name, celebrity likeness, or a third-party design element.

Additional Fees – Fees for extra trademark classes, priority claims, or expedited processing.

=> Priority Claim Documents (If Claiming Earlier Rights)

Certified Copy of Foreign Trademark – If filing based on an existing international trademark.
Translation of Documents – Official translations of any non-English documents.

Note:- Each country has different requirements—check with the relevant trademark office for specifics.
Processing times vary but typically range from 6 months to 2 years, depending on jurisdiction and any opposition.

logo is already trademarked check with:- World Intellectual Property Organization’s (WIPO) website and search for your organization’s logo

To use your logo with BIMI, you must get a Verified Mark Certificate (VMC) or a Common Mark Certificate (CMC) from an approved CA. You can work with your legal team or a lawyer to get your logo trademarked

Select a BIMI Certificate Provider:- Now need to contact VMC cert provider if your logo is ready as per above Step 2.

Certificate Provider Verification:-

When you apply for a Verified Mark Certificate (VMC) for BIMI, the certificate authority (CA)—such as DigiCert or Entrust—performs a strict verification process before issuing the certificate. This ensures that only legitimate businesses with a trademarked logo can display their logo in email inboxes.

=> Steps Involved in VMC Verification

The CA checks if your logo is officially registered as a trademark with a recognized trademark office.
You must provide proof of trademark registration from authorities like:

United States Patent and Trademark Office (USPTO) (https://www.uspto.gov)
European Union Intellectual Property Office (EUIPO) (https://euipo.europa.eu)
World Intellectual Property Organization (WIPO) (https://www.wipo.int)

Logos that are NOT trademarked will be rejected from the VMC process.

=> Domain Ownership Verification

The CA verifies that you own and control the domain for which you are requesting the VMC.
This is done via a DNS TXT record or WHOIS lookup.
The domain must be DMARC-compliant with a policy of p=quarantine or p=reject to qualify for BIMI.

=> Business Identity Validation

The CA confirms that your business is legally registered and active.
You must submit: Legal business name, Address & registration details, Government-issued business license or incorporation documents
The CA checks these details against public and government records to ensure authenticity.

=> Contact Person Verification

You must designate a verified individual as the certificate contact person.
This person must prove their identity using a government-issued photo ID (passport, driver’s license), Company email, and phone verification.

=> Final Approval & Certificate Issuance

Once all the above verifications are completed, the CA issues the VMC certificate.
The certificate is digitally signed and tied to your verified domain and logo.
After approval, you can publish your BIMI record (DNS TXT record) to activate logo display in email clients.

 

Add a BIMI TXT Record to Your DNS:-

It might surprise you to hear that BIMI also incorporates the idea of a selector for publishing an assertion record in a similar manner to DKIM. This could be utilized to have alternative logos between your corporate email, or different brands using the same email domain. Should you only have the need for one logo you can publish your BIMI record under the ‘default’ selector.

default._bimi.example.com TXT “v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem”

v=BIMI1; → Specifies the BIMI version (always “BIMI1”).
 l=URL → The location (URL) of the brand logo in **SVG format**.
a=URL → The URL of the **Verified Mark Certificate (VMC)** issued by a CA (DigiCert, Entrust).

host -t txt default._bimi.linkedin.com
default._bimi.linkedin.com descriptive text “v=BIMI1; l=https://media.licdn.com/media/AAYQAQQhAAgAAQAAAAAAABrLiVuNIZ3fRKGlFSn4hGZubg.svg; a=https://media.licdn.com/media/AAYAAQQhAAgAAQAAAAAAALe_JUaW1k4JTw6eZ_Gtj2raUw.pem;”

host -t txt default._bimi.cnn.com
default._bimi.cnn.com descriptive text “v=BIMI1; l=https://amplify.valimail.com/bimi/time-warner/I0vDrJpkRnB-cable_news_network_inc2025.svg; a=https://amplify.valimail.com/bimi/time-warner/I0vDrJpkRnB-cable_news_network_inc2025.pem”

 

BIMI Work Without a Website?
1. BIMI Requirements
Domain Authentication: To implement BIMI, you need to have your email domain authenticated using DMARC (Domain-based Message Authentication, Reporting & Conformance).
SVG Logo: You must have a logo in SVG format that meets specific requirements.
BIMI Record: You need to publish a BIMI record in your domain’s DNS settings.

2. Website Not Required
No Website Needed: Technically, you do not need an active website for BIMI to work. The essential requirements are:
A domain with DMARC configured.
A valid SVG logo hosted somewhere accessible via HTTPS.
A BIMI DNS record pointing to the logo.

3. Hosting the Logo
Logo Hosting: If you do not have a website, you can host your SVG logo on a third-party service that supports HTTPS. This could be a cloud storage service or an image hosting platform that allows direct linking.

Once you have your VMC, update your organizational domain’s DNS with a BIMI TXT record and ALL subdomains will inherit it from this org/root/top-level domain. is this correct?
Yes, but dmarc/dkim is required for each domain subdomain.

HTTP status codes are three-digit responses sent by a web server to indicate the outcome of a client’s request to the server. These codes help the client understand whether a request was successful, whether there was an error, or if further action is needed.

 

Status Code Category Description
1XX Informational Informational responses indicate that the request was received and understood, and further action is needed by the client.
100 Informational Continue: The client should continue with its request.
101 Informational Switching Protocols: The server is switching protocols as requested by the client.
102 Informational Processing: The server has received and is processing the request, but no response is available yet.
103 Informational Early Hints: Provides preliminary responses to the client before the final response is ready.
2XX Success Success codes indicate that the client’s request was successfully received, understood, and accepted.
200 Success OK: The request was successful, and the server returned the requested resource.
201 Success Created: A new resource was successfully created.
202 Success Accepted: The request has been accepted for processing but is not yet completed.
203 Success Non-Authoritative Information: The request was successful, but the information may come from a different source.
204 Success No Content: The request was successful, but there is no content to return.
205 Success Reset Content: The client should reset the view or form that sent the request.
206 Success Partial Content: The server is delivering only part of the resource due to a range header sent by the client.
207 Success Multi-Status: The response contains multiple status codes, used for WebDAV.
208 Success Already Reported: The members of a DAV binding have already been enumerated in a previous reply.
226 Success IM Used: The server fulfilled a GET request for the resource, and the response is a result of instance-manipulations applied to the current instance.
3XX Redirection Redirection codes indicate that further action needs to be taken by the client to complete the request.
300 Redirection Multiple Choices: The request has more than one possible response. The user-agent or user should choose one of them.
301 Redirection Moved Permanently: The resource has been permanently moved to a new URL.
302 Redirection Found: The resource is temporarily available at a different URL.
303 Redirection See Other: The client should retrieve the resource from another URI using a GET request.
304 Redirection Not Modified: The resource has not been modified since the last request, so the client can use the cached version.
307 Redirection Temporary Redirect: The resource is temporarily available at a different URI, and the request method should not change.
308 Redirection Permanent Redirect: The resource has been permanently moved to a new URI, and the request method should not change.
4XX Client Error Client error codes indicate that the client seems to have made an error in the request.
400 Client Error Bad Request: The server cannot process the request due to a client error (e.g., malformed syntax).
401 Client Error Unauthorized: Authentication is required to access the resource.
402 Client Error Payment Required: Reserved for future use.
403 Client Error Forbidden: The server understood the request but refuses to authorize it.
404 Client Error Not Found: The requested resource could not be found on the server.
405 Client Error Method Not Allowed: The request method is not supported for the requested resource.
406 Client Error Not Acceptable: The requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.
407 Client Error Proxy Authentication Required: The client must first authenticate itself with the proxy.
408 Client Error Request Timeout: The server timed out waiting for the request.
409 Client Error Conflict: The request could not be completed due to a conflict with the current state of the resource.
410 Client Error Gone: The resource requested is no longer available and will not be available again.
411 Client Error Length Required: The request did not specify the length of its content, which is required by the requested resource.
412 Client Error Precondition Failed: The server does not meet one of the preconditions that the requester put on the request.
413 Client Error Content Too Large: The request is larger than the server is willing or able to process.
414 Client Error URI Too Long: The URI provided was too long for the server to process.
415 Client Error Unsupported Media Type: The media format of the requested data is not supported by the server.
416 Client Error Range Not Satisfiable: The range specified by the Range header field in the request cannot be fulfilled.
417 Client Error Expectation Failed: The server cannot meet the requirements of the Expect request-header field.
421 Client Error Misdirected Request: The request was directed at a server that is not able to produce a response.
422 Client Error Unprocessable Content: The server understands the content type of the request entity, but was unable to process the contained instructions.
423 Client Error Locked: The resource that is being accessed is locked.
424 Client Error Failed Dependency: The request failed due to failure of a previous request.
425 Client Error Too Early: Indicates that the server is unwilling to risk processing a request that might be replayed.
426 Client Error Upgrade Required: The server refuses to perform the request using the current protocol but might be willing to do so after the client upgrades to a different protocol.
428 Client Error Precondition Required: The origin server requires the request to be conditional.
429 Client Error Too Many Requests: The user has sent too many requests in a given amount of time.
431 Client Error Request Header Fields Too Large: The server is unwilling to process the request because its header fields are too large.
451 Client Error Unavailable for Legal Reasons: The resource is unavailable due to a legal demand to deny access to it.
5XX Server Error Server error codes indicate that the server failed to fulfill a valid request.
500 Server Error Internal Server Error: The server encountered an unexpected condition, such as a misconfigured application or script error, that prevented it from fulfilling the request.
501 Server Error Not Implemented: The server does not support the functionality required to fulfill the request, often due to a missing module or unsupported method.
502 Server Error Bad Gateway: The server, while acting as a gateway or proxy, received an invalid response from an upstream server, often due to a reverse proxy or gateway issue.
503 Server Error Service Unavailable: The server is temporarily unable to handle the request due to temporary overloading or maintenance of the server.
504 Server Error Gateway Timeout: The server, acting as a gateway or proxy, did not receive a timely response from an upstream server or some other auxiliary server (e.g., DNS) it needed to access in order to complete the request.
505 Server Error HTTP Version Not Supported: The server does not support the HTTP protocol version used in the request.
506 Server Error Variant Also Negotiates: The server has an internal configuration error: the chosen variant resource is configured to engage in content negotiation itself, and is therefore not a proper endpoint in the negotiation process.
507 Server Error Insufficient Storage: The server is unable to store the representation needed to complete the request, often due to a lack of disk space.
508 Server Error Loop Detected: The server detected an infinite loop while processing a request with a resource, often due to circular references.
511 Server Error Network Authentication Required: The client needs to authenticate to gain network access, often required by captive portals.

Shared Client IP Pool for Email Sending

by | Dec 3, 2024 | Linux

A shared client pool is essential for email sending as it allows us to maintain a collection of IP addresses and resources that multiple clients can use. This approach optimizes resource management, ensures load balancing, and provides a stable service—especially for smaller senders or new customers who lack the email volume to justify their own dedicated IP.

Why Do We Need Shared Client Pools?
1. IP Pool Management

By pooling IP addresses, we can rotate and manage sending IPs effectively.
This prevents overloading any single IP, which could lead to deliverability issues.
Pooling also enables better management of sender reputation by distributing email traffic across different IPs.

2. Pre-Warmed Reputation

If the majority of senders follow good practices, the pool benefits from an established positive reputation.
Smaller senders or new accounts can achieve good deliverability without needing to build their own reputation from scratch.

3. Inconsistent and Low Volumes

Shared IP pools are ideal for clients with low or inconsistent email volumes.
ISPs like Yahoo, Microsoft, and Google deprioritize emails from low-volume or inconsistent IPs, making shared pools a more reliable option.

4. Warm-Up

Shared IPs are already warmed up and actively used, eliminating the need to gradually increase email volume as required for a dedicated IP.

5. Cost-Management

Dedicated IPs come with additional fees, whereas shared IP pools provide better deliverability at a lower cost.
Depending on one or two dedicated IPs increases the risk of deliverability issues, but shared pools distribute traffic across multiple IPs, mitigating that risk.

6. Reputation Management

A shared client pool helps maintain a consistent sender reputation.
We use shared reputation scores for IPs and domains, benefiting all clients by improving overall deliverability.

7. Minimize the Risk

Clients with similar sending patterns can be grouped together, minimizing risks and ensuring consistent deliverability across the shared pool.

Shared client pools are crucial for maintaining reliable email deliverability. They are especially beneficial for small or new senders by providing cost-effective, reputation-enhancing, and risk-reducing email sending solutions compared to dedicated IPs.
