BIMI Checker
Validate whether a domain has the DMARC enforcement, BIMI DNS, logo, and certificate evidence signals that participating mailbox providers can evaluate.
About this tool
BIMI is a brand-readiness layer that sits after SPF, DKIM, and DMARC. This checker looks for the default BIMI selector, validates the DNS record shape, checks DMARC enforcement eligibility, and reports whether logo and certificate evidence are ready for provider-side evaluation.
A passing BIMI check does not guarantee logo display. Gmail, Yahoo, Apple Mail, and other mailbox surfaces apply their own certificate, reputation, engagement, and provider-header rules. The useful operator question is whether your domain is eligible, what is blocking readiness, and what to fix next.
For continuous monitoring, drift alerts, evidence history, and team workflows, Starter and Growth include a 14-day free trial.
