About BIMI Checker

This tool looks up the default._bimi TXT record for your domain, validates the SVG logo URL, checks Verified Mark Certificate (VMC) status, and confirms the DMARC p=quarantine/reject prerequisite. Tells you exactly which mailbox providers (Gmail, Apple Mail, Yahoo, Fastmail) will display your logo and why.

How the BIMI check works

DNS, SVG, VMC, DMARC — all validated

01

Fetch BIMI record

Looks up default._bimi.yourdomain.com via DNS-over-HTTPS. Parses the l= (logo URL) and a= (VMC URL) tags from the record.

02

Validate SVG logo

Fetches the SVG file at the l= URL. Checks file is reachable (HTTPS, 2xx response), valid SVG, follows SVG Tiny Portable/Secure spec (no scripts, no external references).

03

Cross-check DMARC requirement

BIMI only activates with DMARC at p=quarantine or p=reject (pct=100). We flag if DMARC is at p=none or partial enforcement — Gmail and Apple Mail will not display the logo.

Common BIMI errors this catches

Why your BIMI logo is not appearing

DMARC not at quarantine/reject

BIMI requires DMARC p=quarantine or p=reject with pct=100. Domains at p=none or partial enforcement (pct=10) will not show BIMI logos in any mailbox provider. Most common reason BIMI doesn't work.

Missing VMC (Verified Mark Certificate)

Gmail and Apple Mail require a VMC tied to a registered trademark. Without it, only Yahoo and Fastmail show your logo. VMCs cost $1,500-$2,000/year from Entrust or DigiCert.

SVG fails SVG Tiny PS spec

Standard SVGs include scripts, external links, animations — all banned by the BIMI spec. Logo must be SVG Tiny Portable/Secure. Test conformance at bimigroup.org tools before publishing.

Logo URL returns 404 or non-2xx

BIMI receivers fetch the logo at every render. If your CDN, S3 bucket, or hosting expires the URL, the logo silently stops showing. Use a stable, monitored URL.

Wrong selector (not "default")

BIMI uses selectors like SPF/DKIM. The default selector is "default._bimi", but you can use multiple selectors per domain. We auto-detect common selectors but flag if "default" is missing.

Subdomain not inheriting BIMI

BIMI does not propagate from root to subdomain. If you publish at example.com, mail.example.com won't inherit. Publish per subdomain or use the same SVG URL in each record.

FAQ

BIMI checker — common questions

What is a BIMI record?+
BIMI (Brand Indicators for Message Identification) is a DNS TXT record at default._bimi.yourdomain.com that publishes the URL of your brand logo (as an SVG) and optionally a Verified Mark Certificate (VMC). When configured correctly, your logo appears next to your emails in Gmail, Apple Mail, Yahoo, and Fastmail — increasing recognition and reducing phishing.
What are the requirements to use BIMI?+
You need: (1) DMARC at p=quarantine or p=reject with pct=100 (p=none and partial enforcement do not qualify), (2) an SVG Tiny PS logo file at a public HTTPS URL, (3) for Gmail and Apple Mail you also need a VMC — a paid certificate from Entrust or DigiCert ($1,500-$2,000/year) tied to a registered trademark. Yahoo and Fastmail show logos without VMC.
Why does my BIMI record exist but my logo does not show in Gmail?+
Most common cause: missing VMC. Gmail and Apple Mail will not show BIMI logos without a Verified Mark Certificate. Other causes: DMARC not at p=quarantine/reject yet, BIMI policy specifying an SVG that fails the SVG Tiny PS spec (wrong size, includes scripts, has external references), or the logo URL returns a 404 / non-2xx response.
How do I create a valid BIMI SVG logo?+
BIMI requires SVG Tiny Portable/Secure (SVG Tiny PS) format — a stripped-down SVG without scripts, external references, animations, or interactivity. Use a square 1:1 aspect ratio, with the logo centered. Most logo SVGs need editing to comply. Adobe Illustrator and tools like SVG Crop + manual XML editing produce conformant files. Test with bimigroup.org/bimi-generator/svg-conversion-tool/.
Is BIMI worth the cost for small businesses?+
For SMBs sending marketing emails to consumers, BIMI is mixed. It increases brand recognition and click-through rates 5-20% in tests, but VMC certificates ($1,500-$2,000/year) only pay back if you send high volumes. For B2B-only senders or low-volume domains, BIMI without VMC (Yahoo + Fastmail only) is often enough. For high-volume B2C senders, the VMC investment usually pays back through deliverability and engagement gains.
