BIMI Record Checker

BIMI (Brand Indicators for Message Identification) is an email standard that allows organizations to display their brand logo in email clients' inbox UI. When BIMI is properly configured, Gmail, Apple Mail, and other supporting clients show your logo next to your emails, increasing trust and open rates. BIMI requires: (1) A BIMI DNS TXT record at default._bimi.{domain}, (2) A DMARC record with p=quarantine or p=reject, and (3) An SVG logo hosted at a public URL. Major clients like Gmail also require a VMC (Verified Mark Certificate) from DigiCert or Entrust to show the logo.

A VMC is a digital certificate that validates your brand's trademark ownership alongside your BIMI logo. Gmail requires a VMC to display BIMI logos — without it, Gmail shows a blue "verified" checkmark but not the actual logo. VMCs are issued by certified Certificate Authorities (currently DigiCert and Entrust) and require a registered trademark. VMCs cost $1,000-$1,500/year. For Google Workspace domains, Google offers a simpler path called BIMI with CMC (Common Mark Certificate) that doesn't require trademark registration.

BIMI requires your DMARC policy to be either p=quarantine or p=reject. A policy of p=none is insufficient — it means unauthenticated emails are not blocked, which would allow spoofing. Most email clients will not display BIMI logos for domains with p=none. To upgrade: (1) First ensure SPF and DKIM are passing for all your email streams, (2) Monitor DMARC aggregate reports (rua=) to identify legitimate sources, (3) Move to p=quarantine once you're confident all legitimate email is authenticated, (4) Then move to p=reject for maximum protection.

BIMI requires an SVG Tiny PS (SVG Tiny 1.2 Portable/Secure) format — not just any SVG. Requirements: (1) File format must be SVG Tiny PS, (2) Logo must be square (1:1 aspect ratio), (3) Should be simple and recognizable at small sizes (40×40px), (4) Must be hosted at an HTTPS URL, (5) File should ideally be under 32KB, (6) No embedded scripts, external references, or animations. Most mail clients also prefer the logo to have a solid background rather than transparency. Tools like the Canva BIMI SVG generator can create compliant SVGs.

As of 2024: Gmail (requires VMC or Google CMC), Apple Mail (iOS 16+, macOS Ventura+, requires VMC), Yahoo Mail, AOL Mail, Fastmail, Proton Mail, and Netcore. Outlook does not support BIMI yet. Gmail has the largest impact — it shows either the BIMI logo (with VMC) or a verified blue tick (without VMC but with valid BIMI record and p=reject DMARC). Samsung Mail (Android) supports BIMI. The standard is growing — new clients are adding support regularly.
