Getting Started

What is BIMI?

BIMI, Brand Indicators for Message Identification, is an emerging standard for inserting registered trademarks inside email clients that makes it simple for organizations to display their brand on emails.

The idea behind developing BIMI guidelines was to promote a safer email ecosystem by accelerating DMARC adoption and giving brands an incentive to properly implement DMARC (Domain-based Message Authentication, Reporting & Conformance). This incentive was designed in the form of a Verified Mark Certificate, VMC, that enables an organization's verified logo to be displayed in an inbox. To use BIMI at the highest level of validation, organizations require a VMC from an authorized certification authority, such as Entrust, and a DMARC policy set to 100% quarantine or reject.

Why is BIMI important?

By incentivizing organizations to implement DMARC, BIMI promotes a more secure email ecosystem for all. The required DMARC policy helps in improving security against spoofing and phishing attacks. The display of the logo in the inbox brings immediate brand recognition and boosts email engagement. Together, these BIMI requirements help organizations create an enhanced experience for their customers. Early adopters can differentiate their brand while showing their customers that they have implemented best practices.

What is a VMC (Verified Mark Certificate)?

VMC is the digital certificate that enables organizations to display their registered trademark logos alongside outbound emails in accordance with the BIMI guidelines. VMCs help organizations create a more immersive and personalized email experience for their customers and elevate their overall email strategy.

Why do I need a VMC?

Business email compromise (BEC) continues to disrupt consumer trust and leads to costly fraudulent activity. New enhanced personalization methods that can drive more immersive email experiences safely help to improve email strategy. Combining VMCs with the required DMARC authentication and anti-spoofing technology helps to reduce email spoofing and phishing and improve deliverability.

VMCs help brands create a more engaging email experience for their customers and bring best practices to their email strategy.

What is DMARC?

DMARC is an email authentication protocol that was developed to give email domain owners the ability to prevent email spoofing.

Deep Dive


What is the approximate time it would take to get BIMI via a Verified Mark Certificate if starting without DMARC or a registered trademark logo?

DMARC compliance takes an average of five to eight weeks, depending on the number of sources there are to configure and the speed at which you can implement the needed records. It can take anywhere from three to six months or more to get a registered trademark, depending upon country.

Is BIMI expected to become a new internet standard?

There is currently an IETF draft under review, but there is no internet standard yet.

Can BIMI be attached to CRM-generated emails that may be sent from a different IP?

Yes, but only if the email sender is authorized to send via the DMARC-compliant policy.

What is a BIMI record?

A BIMI record is a TXT record that needs to be added to the organization's DNS record for the email domain(s) licensed by the VMC. It contains the hosting location of the registered trademark logo and the VMC associated with the email domain.

Where are the company logos that are used for Verified Mark Certificate records sourced?

The registered logo is provided by your company for authentication as an image in SVG Tiny format. Once authenticated, a VMC is created with this image and hosted by the customer or Entrust. A BIMI record is placed in your DNS, which provides the URL where the VMC is hosted.

Where do we upload the registered logo that we want to show up in email communications?

Entrust will host the VMC and SVG logo by default, but it also can be uploaded to any public-facing website secured with a TLS/SSL certificate. The URLs will need to be placed in your DNS as a BIMI TXT record.

Is BIMI available for only B2C email deployment? What about B2B?

BIMI will show the registered logo on any supported mailbox provider as long as the email domain and organizational domain (if relevant) is BIMI-enabled. Note: Google and Apple only support BIMI with Verified Mark Certificates.

Do I need to send a high volume of email to be eligible for BIMI?

No. Any sender, regardless of volume, can be eligible for BIMI if they have a registered trademark logo and DMARC compliance.

Yes, a registered trademark is one of the requirements for a VMC to be issued.

What is the difference between BIMI and a Verified Mark Certificate (VMC)?

BIMI is the protocol that enables organizations to display a registered logo alongside email messages. A VMC verifies that the logo belongs to that company and that it is a legitimate company. A VMC ties into the BIMI record as a tamper-proof security measure.

BIMI can convey an image via an SVG file or a VMC. At present, Yahoo only supports SVG display while Google and Apple only support VMCs.

To have a registered trademark logo, does our company name also need to be registered?

No, only the registered logo that will be used for BIMI needs to be registered.
