BIMI stands for Brand Indicators for Message Identification, a standard that lets you attach your company's emblem to verified emails. This aids in the development of subscriber trust and brand recognition.
When a valid email from your firm is received, the BIMI standard ensures that your brand logo is displayed alongside it. In addition to DMARC protection, BIMI helps guard against consumer phishing attempts in which fraudsters attempt to send fraudulent emails using your domain.
BIMI Record and BIMI Header
A BIMI header isn't required for all organizations, but it may surely assist in garnering trust and recognition for your brand. Larger consumer-facing businesses could substantially benefit from having a BIMI record in their email. It can even be argued that having a BIMI record in place is more crucial the larger and more well-known the brand is. Because BIMI is a relatively new email authentication standard, most companies do not bounce or flag inbound emails if a BIMI record is missing.
This, however, may change in the future as more email providers embrace BIMI. Setting up BIMI is simple, and it's well worth the time and effort if you want to safeguard your email subscribers while also improving brand impressions and conversions.

BIMI Selector-Header
A BIMI-Selector header gives you additional options for displaying numerous logos for different companies based on subdomains. A BIMI header isn't necessary for a BIMI record, but it does provide this extra capability.
When your email doesn't include a BIMI header, the DNS query is done using the default selection in the domain's ‘From:’ field. You may also create a BIMI TXT record for the specified ‘From:’ domain to modify this.
After you've implemented BIMI, you might wish to utilize a BIMI header to change the brand or logo displayed depending on the subdomain sending the email. This is ideal for major businesses or subdomains that are solely dedicated to delivering marketing emails.
The BIMI header is added to the DNS server that your domain uses as a TXT record, just like a BIMI record. To work, the selector value in the BIMI header record must match the selector name in the DNS record.
Syntax of a BIMI header record:
V = Version: This will always begin with ‘BIMI1’ and will be at the start of the record.
S = Selector Name: This is the name that you provide the selector. In order to operate, this name must match both the BIMI Header and the BIMI DNS record.
A BIMI-Selector header example:
Sender's email address: sender@domain.com.
BIMI-Selector: v=BIMI; s=selector
Now that you are aware of how BIMI-Selector Header works, implement it for your domain without further delay to reap all the benefits that BIMI provides including keeping your domain spoof-free and helping you build consumer trust.
