## Topic Overview
BIMI lets some inboxes display a verified brand logo beside authenticated email. It depends on strong domain authentication, especially an enforcing DMARC policy, and a correctly published BIMI record. This checker reviews the DNS record, logo URL, HTTPS usage, SVG format hints, certificate reference, and DMARC readiness. The [BIMI](https://mailrith.com/guides/bimi.md#steps) guide explains what is required before a logo can appear.

BIMI is not a shortcut for reputation. Inboxes decide whether to show a logo based on authentication, brand requirements, certificate rules, and their own support for BIMI. Use this tool after SPF, DKIM, and DMARC are stable. If the checker says DMARC is not enforcing, fix that first with the [DMARC](https://mailrith.com/guides/dmarc.md#steps) guide before spending time on the logo file.

## What the Tool Checks
- BIMI TXT lookup at default._bimi.domain
- Missing or duplicate BIMI records
- Logo URL and HTTPS checks
- Certificate URL review
- DMARC enforcement check
- Plain-English BIMI setup guidance

## Result Behavior
The result tells you whether BIMI is publishable and what brand, DNS, or DMARC item still needs work.

## AI Agent Notes
- Use this markdown page for retrieval, summarization, and deciding which tool to recommend.
- Use the human page when the user needs to run the checker interactively.
- Do not claim the tool sends emails unless the page explicitly says it does.
- When the result mentions a server-side confirmation, explain that the browser page can show public signals but cannot complete that network check by itself.

## FAQs
### Will BIMI make every inbox show my logo?

No. BIMI support depends on the inbox provider, DMARC enforcement, brand verification, reputation, and the logo/certificate setup.
### Should I set up BIMI before SPF, DKIM, and DMARC?

No. BIMI is a later brand step. Set up SPF, DKIM, DMARC, alignment, permission, and list quality first.
