Boost trust and brand recognition with every email. Validate your BIMI record, logo URL, and VMC certificate.
The BIMI Checker looks up your published BIMI DNS TXT record at selector._bimi.yourdomain.com and validates the logo URL, VMC certificate, and DMARC eligibility.
BIMI (Brand Indicators for Message Identification) lets supported inbox providers display your brand logo next to authenticated email, but only when DMARC is enforced and your assets meet spec.
See the exact BIMI record receivers find for your domain and selector.
Verify your SVG logo URL is reachable and your VMC certificate is present and valid.
Confirm your DMARC policy meets BIMI requirements (quarantine or reject).
Parsed v, l, and a tags with descriptions for quick troubleshooting.
Provide your sending domain and BIMI selector (usually default).
The tool looks up selector._bimi.yourdomain.com for the BIMI TXT record.
DMARC policy, logo URL accessibility, and VMC certificate are checked.
Read status cards, tag details, and issues to confirm BIMI readiness.
BIMI requires enforced DMARC (p=quarantine or p=reject), a valid SVG Tiny PS logo, and a VMC certificate for most major providers.
BIMI record is present, syntactically valid, and no actionable issues were found.
Record exists but has gaps, missing VMC, logo not accessible, or DMARC not enforced.
No BIMI record at the selector, or the published value has syntax errors.
BIMI will not display in most inboxes until DMARC policy is quarantine or reject.
Valid, Invalid, or Not found, based on DNS presence and syntax.
Whether a VMC (a= tag) exists and passes validation.
Whether the l= URL is specified and the SVG logo is accessible over HTTPS.
Must be Enforced (quarantine/reject) for BIMI logo display in Gmail and Yahoo.
v=BIMI1, l= logo URL, a= VMC certificate URL.
Move to p=quarantine or p=reject before expecting BIMI logos to appear in inboxes.
Validate your logo with the BIMI Logo Validator and convert if needed before publishing.
Both the logo (l=) and VMC certificate (a=) must be served over HTTPS with valid TLS.
Run the checker after publishing or updating your BIMI record to confirm propagation.
It queries DNS for a TXT record at selector._bimi.yourdomain.com. That record points to your brand logo and optional VMC certificate for inbox display.
Major providers (Gmail, Yahoo) require DMARC at p=quarantine or p=reject before displaying BIMI logos. Monitor-only (p=none) is not sufficient.
A Verified Mark Certificate proves trademark ownership of your logo. It is referenced in the a= tag and required by Gmail for BIMI display.
Most domains use default. The selector becomes part of the DNS host: default._bimi.example.com.
The l= URL could not be fetched, it may be down, blocked, not HTTPS, or not a valid SVG file.
Some providers may show logos without VMC in limited cases, but Gmail requires a valid VMC. Plan to obtain one for full coverage.
DMARC authenticates mail and sets policy. BIMI adds brand logo display on top of DMARC, it does not replace authentication.
SenderSignal monitors these signals continuously: 48 blacklists, SPF, DKIM, DMARC, TLS and more, with alerts in Slack, email and signed webhooks.
