Free BIMI Record Checker
BIMI is what puts your logo next to your emails in the inbox. It only works once DMARC is enforced — this checks both, and tells you in plain English what is standing in the way. No signup required.
Selector is optional — almost every domain uses default. Runs entirely in your browser using public DNS-over-HTTPS. We never store your query.
BIMI needs DMARC at enforcement — that is the hard part. PlainDMARC watches your DMARC reports every week and tells you in plain English when it is safe to tighten, so you get there without breaking your own mail.

Frequently asked questions
What is BIMI?
BIMI (Brand Indicators for Message Identification) is a DNS record that tells mailbox providers where to find your logo. Supporting providers show that logo next to your messages instead of a generic initial. It is published as a TXT record at default._bimi.yourdomain.com.
Why does my logo not show even though I have a BIMI record?
Almost always because DMARC is not enforced. Mailbox providers only display a BIMI logo when the domain's DMARC policy is p=quarantine or p=reject — a domain at p=none gets nothing, no matter how correct the BIMI record is. This checker looks at both and tells you which one is missing.
Do I need a Verified Mark Certificate?
For Gmail, yes. Gmail requires a VMC (or a Common Mark Certificate) issued by a certificate authority, which needs a registered trademark and is a paid annual certificate. Other providers, including Yahoo and Apple Mail, can display a logo from the record alone. That is why this checker reports the two cases separately.
What kind of image file does BIMI need?
A specific constrained form of SVG called SVG Tiny Portable/Secure, served over HTTPS. Ordinary SVG exports usually fail, because the profile forbids scripts, external references and animation. This checker verifies the record points at an HTTPS .svg URL; it does not fetch or validate the file itself.
