Query Domain BIMI & DMARC Records
Browser-Native Brand Indicators for Message Identification (BIMI) Audit & Inbox Simulator
Brand Indicators for Message Identification (BIMI) enables domain owners to display verified brand logos beside authenticated emails in supporting recipient inboxes such as Gmail, Apple Mail, and Yahoo Mail. The BIMI Previewer delivers a comprehensive browser-native workspace for auditing DNS BIMI records, validating SVG vector formatting, and testing inbox visual readiness without exposing private sender configurations to tracking networks.
This utility performs end-to-end evaluation of the BIMI publication chain. It validates the mandatory DMARC enforcement policy prerequisite (requiring p=reject or p=quarantine with pct=100), inspects BIMI TXT records across custom selectors, verifies HTTPS logo and Verified Mark Certificate (VMC) locations, and audits SVG vector markup against the strict BIMI SVG Tiny P/S (Portable/Secure) specification.
Equipped with live DNS-over-HTTPS resolution, an interactive SVG security inspector, and a realistic multi-client inbox simulator supporting light and dark themes, the workspace ensures marketing teams, deliverability engineers, and security specialists can deploy brand marks with complete confidence and compliance.
Core Tool Capabilities
- BIMI DNS Record Parsing and Verification: Parses TXT records at default._bimi or custom selectors to confirm valid v=BIMI1 syntax, HTTPS image URIs, and optional VMC certificate locations.
- DMARC Enforcement Prerequisite Audit: Evaluates domain DMARC policies to guarantee strict enforcement compliance (p=reject or p=quarantine with pct=100) required for BIMI mailbox display.
- SVG Tiny P/S Profile and Security Audit: Scans vector artwork to confirm viewBox presence, script and event handler suppression, and self-contained asset requirements.
- Multi-Client Inbox Mockup Simulation: Previews how brand logos render in Gmail, Apple Mail, and Yahoo Mail avatar slots across light and dark user interface modes.

Frequently Asked Questions
- Why is a strict DMARC policy required for BIMI?
- Mailbox providers only render BIMI logos for domains protected against spoofing. DMARC must be set to p=reject or p=quarantine with pct=100 across both organizational domains and subdomains.
- What is a Verified Mark Certificate (VMC)?
- A VMC is a digital certificate issued by a recognized Certification Authority that validates your organization's legal ownership of a registered trademark logo.
- Can I use a PNG or JPG image for BIMI?
- No. BIMI strictly requires vector graphics in SVG Tiny P/S (Portable/Secure) format. Bitmap formats such as PNG, JPG, or GIF are not supported by mailbox providers.
- Where is the BIMI DNS record published?
- BIMI records are published as TXT records at selector._bimi.domain.com. The standard default selector is default._bimi.example.com.
- Does this utility upload my SVG or domain to a remote server?
- No. All record parsing, SVG profile validation, and inbox simulations run entirely within your local browser sandbox.
