Free BIMI Record Checker & SVG Logo Validator
Find out whether your domain’s logo will actually render in Gmail and Yahoo inboxes. This checker resolves the live BIMI TXT record, fetches the referenced SVG logo over verified HTTPS, checks for a VMC authority record, and validates the DMARC enforcement prerequisite (p=reject, or quarantine with pct=100) that inboxes demand.
BIMI Record & SVG Logo Inspector
Check your domain’s BIMI TXT record (`default._bimi.domain.com`), inspect whether your brand SVG logo is publicly accessible over HTTPS, and verify strict DMARC prerequisite compliance.
Tool Overview: What It Does & Core Purpose
Brand Indicators for Message Identification (BIMI) empowers email senders to display their authenticated corporate logo directly next to incoming messages inside supported inboxes like Gmail, Apple Mail, and Yahoo Mail. The **AutoSMTP BIMI Checker** queries your authoritative DNS for the published BIMI assertion record, validates syntax compliance under the BIMI specification, inspects whether your SVG logo satisfies the strict SVG Tiny Portable/Secure (Tiny P/S) profile, and confirms that your domain enforces the non-negotiable DMARC quarantine or reject prerequisite.Key Advantages & Architectural Benefits
Advantage
**DMARC Alignment Verification:** Automatically cross-checks whether your root domain enforces `p=quarantine` (`pct=100`) or `p=reject`.
Advantage
**SVG Logo Endpoint Probing:** Sends live HTTP HEAD requests to verify that the SVG URL is reachable over TLS with correct MIME headers.
Advantage
**VMC Certificate Inspection:** Detects the presence of an authority URL (`a=`) pointing to a cryptographically validated Verified Mark Certificate.
Advantage
**Selector Flexibility:** Allows testing across standard `default` selectors or specialized organizational campaign selectors.
Email Marketing & Cold Outreach Integration
How This Tool Accelerates Email Campaigns & Deliverability
Displaying your verified logo in recipient inboxes yields immediate open rate lift (averaging 15–28% according to industry deliverability benchmarks) while establishing immediate sender authenticity. AutoSMTP’s dedicated infrastructure supports automated BIMI drift monitoring, notifying you if DNS records change or SVG assets fail accessibility checks.Frequently Asked Questions (FAQs)
What is the primary prerequisite for BIMI to display in Gmail? ▾
Gmail mandates both a strict DMARC policy (`p=quarantine` with `pct=100` or `p=reject`) AND a Verified Mark Certificate (VMC) issued by an approved certificate authority (such as DigiCert or Entrust) confirming registered trademark ownership.
Can I use PNG or JPEG images for BIMI? ▾
No. The BIMI specification strictly requires SVG format, specifically adhering to the SVG Tiny 1.2 Portable/Secure (SVG Tiny P/S) profile. Standard web SVGs with external script tags or embedded raster images will fail validation.
Where should the BIMI record be published in DNS? ▾
It must be published as a TXT record at `[selector]._bimi.[yourdomain.com]`. The industry standard default selector is `default`, making the record location `default._bimi.yourdomain.com`.
Does Yahoo Mail require a VMC for BIMI? ▾
Yahoo Mail supports BIMI without a VMC for senders with exceptionally high sender reputation, but strongly encourages VMCs for guaranteed visual rendering.

The BIMI and VMC ecosystem
Publishing the BIMI TXT record is the easy half. Whether your logo actually renders depends on each mailbox provider’s certificate policy. Gmail and Apple require a Verified Mark Certificate (VMC) — an annual certificate in which a CA (currently DigiCert or Entrust) verifies that your organization legally controls the trademark covering the exact logo artwork. Expect roughly $1,000–$1,500 per year and a validation process that runs from days to a few weeks. The newer Common Mark Certificate (CMC) covers US-registered common-law marks at a lower price point. Yahoo
The technical prerequisites are free and this checker verifies all of them: DMARC at enforcement (p=reject, or p=quarantine with pct=100), a square tiny-profile SVG served over valid HTTPS, and the record’s Mailbox providers only burn logo-rendering real estate for domains that actively prevent spoofing. Monitoring-only DMARC (p=none) disqualifies BIMI at Gmail and Yahoo. Gmail and Apple require a Verified Mark Certificate for the brand logo; Yahoo accepts standard BIMI marks. The checker reports whether an authority record is referenced.l= and a= tags resolving. Nail those first — most BIMI failures are DMARC policy or logo-hosting problems, not missing certificates.Frequently asked questions
