💬 What This Record Does

Brand Indicators for Message Identification (BIMI) lets you display your company's logo next to emails in supporting inboxes (Gmail, Apple Mail, Yahoo Mail, Fastmail). The TXT record at default._bimi.example.com points to a hosted SVG logo and an optional Verified Mark Certificate (VMC). BIMI requires a DMARC policy of at least p=quarantine and a domain-aligned DKIM signature. Google and Yahoo also require a VMC from an approved certificate authority.

Common Uses

  • Displaying a verified brand logo in Gmail, Yahoo Mail, and Apple Mail inboxes
  • Increasing email recognition and click rates for transactional or marketing campaigns
  • Demonstrating strong email authentication posture (DMARC p=quarantine/reject required)

⚠️ Watch Out For

  • The SVG must be a square, tiny-profile SVG (SVG Tiny PS) — most standard SVG files fail validation.
  • Gmail requires a Verified Mark Certificate (VMC) from DigiCert or Entrust — this is a paid certificate.
  • BIMI will not display if your DMARC policy is p=none.
