BIMI Record Checker

Check whether a domain has BIMI configured and see which email clients will display its logo. BIMI builds on DMARC, and full enforcement is a hard prerequisite.

Checked in your browser, no account required. Monitor your DMARC posture continuously.

What BIMI requires to work

BIMI (Brand Indicators for Message Identification) lets you display your logo next to your emails in supporting clients. Before it works, you need DMARC at p=quarantine or p=reject, a properly formatted SVG hosted at a specific path, and a valid BIMI DNS record at default._bimi.yourdomain.com. This tool checks all of it: whether your record exists, whether the logo is reachable, and which clients will actually show it.

What this tool checks

  • BIMI DNS record:whether a valid record exists at default._bimi.yourdomain.com
  • Logo reachability:whether the SVG at your l= URL is publicly accessible
  • VMC certificate:whether a Verified Mark Certificate is present (required for Gmail logo display)
  • Client support:which mail clients will show your logo given your current BIMI configuration

Frequently asked questions

What is BIMI?
BIMI is an email standard that displays your brand logo in the sender field of supporting email clients. It builds on DMARC: you need a strict DMARC policy and aligned email authentication before any client will show your logo. Think of it as the visual confirmation that your domain's email is legitimate and authenticated.
Does BIMI work in Gmail?
Gmail requires a Verified Mark Certificate (VMC) from a Certificate Authority like DigiCert or Entrust, currently around $1,500 per year. Without it, Gmail will not show your logo even if your BIMI record is otherwise correct. Yahoo Mail, Apple Mail, and Fastmail support BIMI without a VMC, so the free path still gets you logo display in those clients.
What do I need before setting up BIMI?
Three things: a DMARC policy of p=quarantine or p=reject with consistent alignment across your sending sources; an SVG logo in TinySVG format hosted at a public HTTPS URL; and a BIMI DNS TXT record pointing to it. For Gmail, add a VMC. See the BIMI setup guide for the full step-by-step.
Is BIMI worth it for small businesses?
For Yahoo Mail, Apple Mail, and other clients: yes, and it costs nothing beyond the time to set up the DNS record and host an SVG. For Gmail specifically: the VMC cost is hard to justify unless you send at significant volume and have measured brand recognition as a deliverability factor. Most indie developers and small teams get meaningful coverage from the free path before considering a VMC.

Not sure your DMARC alignment is solid enough for BIMI?

DMARCdrift monitors your DMARC alignment continuously, so you know when every sender is passing and you're actually ready to add BIMI without risking your policy.
