Domain name

The checker queries the default BIMI DNS record for the entered domain.

What this tool does

This tool queries the BIMI TXT record at default._bimi for a domain through the server DNS resolver.

It shows the published BIMI tags and checks their basic structure without downloading logo or certificate files.

How to use the tool

Enter a domain name without a protocol, path, or email address.
Run the check to query the BIMI record at the default selector.
Review the published record and notes about the version, logo URL, and authority URL.

Useful applications

Checking whether a domain publishes a BIMI record at the default selector.
Documenting a published logo or authority URL from a DNS configuration.
Finding basic syntax errors in a BIMI record before sending test messages.

Notes and limitations

A syntactically plausible BIMI record does not guarantee that mailbox providers will show a brand logo.
The tool does not fetch the referenced SVG logo or certificate file, so it does not assess their contents or availability.

Frequently asked questions

Does the checker verify that mailbox providers display the BIMI logo?

No. The checker validates the DNS record and its basic format. Display also depends on the requirements and decisions of the individual mailbox provider.
