How BIMI Email Authentication Works

When an email is sent, the email provider checks the sender's domain against a list of domains that have been verified by the email provider. If the sender's domain is on the list, the email is considered to be from a trusted source and is more likely to be delivered to the recipient's inbox.

The email provider can also use other methods to verify the identity of the sender, such as checking the sender's IP address against a list of known IP addresses associated with the sender's domain.

BIMI email authentication is a new standard that allows email senders to add a logo or image to their emails that can be used to verify the sender's identity. The logo or image is called a BIMI record, and it can be used by email providers to help their users verify that an email is from a legitimate sender.

BIMI email authentication is based on the DomainKeys Identified Mail (DKIM) standard, which is used to verify the identity of an email sender. DKIM uses cryptographic signatures to verify that an email has not been tampered with in transit. BIMI extends DKIM by adding a logo or image to the email that can be used to verify the sender's identity.

To use BIMI email authentication, email senders must first create a BIMI record for their domain. The BIMI record contains the logo or image that will be used to verify the sender's identity. Email providers can then use the BIMI record to help their users verify that an email is from a legitimate sender.

The Benefits Of BIMI Email Authentication

The internet has become a battleground for email users. Inboxes are constantly bombarded with spam, phishing attempts, and other malicious emails. It's becoming more and more difficult to distinguish between legitimate emails and ones that are trying to trick you.

This is where BIMI comes in.

BIMI (Brand Indicators for Message Identification) is a new standard that allows email users to see which emails are verified as coming from a legitimate source. This verification is done through DNS records, meaning that it's a simple process for email providers to implement.

The benefits of BIMI are twofold:

  1. It helps protect users from phishing and other malicious emails

  2. It allows legitimate brands to stand out in the inbox

The first benefit is self-explanatory. By verifying that an email is coming from a legitimate source, BIMI can help protect users from phishing attempts and other malicious emails.

The second benefit is equally important. In a world where the inbox is constantly bombarded with emails, it can be difficult for legitimate brands to stand out. BIMI provides a way for brands to differentiate themselves in the inbox and ensure that their emails are seen by users.

BIMI is still in its early stages, but it has the potential to be a game-changer for email users. It's a simple and effective way to protect users from phishing and other malicious emails, and it allows legitimate brands to stand out in the inbox.

How To Set Up BIMI Email Authentication For Your Domain

BIMI email authentication is a new standard that allows you to display your company's logo in the inbox of your recipients. This can help your email stand out and be more easily recognized, which can lead to more opens and clicks. BIMI is an opt-in feature, so you'll need to set it up for your domain in order to take advantage of it. Here's how:

  1. Make sure you have a valid, published logo. The logo must be in either .png or .svg format, and it should be at least 144x144 pixels.

  2. Create a TXT record for your domain with the following value:

v=BIMI1; l=https://example.com/logo.png;
  1. Replace "https://example.com/logo.png" with the URL of your logo file.

  2. Publish the TXT record. If you're not sure how to do this, contact your DNS provider.

  3. That's it! Once your TXT record is published, your domain will be automatically authenticated for BIMI.

To maximize your email authentication compliance, you should also consider setting up DKIM authentication policy for your email marketing campaigns as well as Sender Policy Framework (SPF).
