BIMI record support
Why it matters
BIMI (Brand Indicators for Message Identification) displays your company logo directly in Gmail and Apple Mail inboxes, making authenticated email visually distinct from spoofed mail. For high-volume B2C senders, brand recognition in the inbox measurably increases open rates and recipient trust. BIMI requires a DMARC policy at p=quarantine or p=reject as a prerequisite, meaning it also validates that your domain's authentication stack is at enforcement level. Absence of BIMI is a missed opportunity for inbox differentiation at the accounts where it matters most — Gmail and Apple Mail — per the 2022 BIMI specification.
Severity rationale
Info because BIMI absence has no deliverability impact and is only relevant for high-volume B2C senders who have already achieved DMARC enforcement and consistent brand sending.
Remediation
Once DMARC enforcement is in place, publish the BIMI record at default._bimi.yourdomain.com:
default._bimi.yourdomain.com TXT "v=BIMI1; l=https://yourdomain.com/brand/logo.svg; a=https://yourdomain.com/brand/cert.pem"
The SVG must conform to the BIMI SVG Tiny PS profile — square, no external references, no scripts. For Gmail logo display a Verified Mark Certificate (VMC) from Entrust or DigiCert is required and must be referenced in the a= tag. Track this record in your infrastructure-as-code alongside SPF, DKIM, and DMARC so any domain authentication migration keeps BIMI in sync.
