Endpoint
bimi-checker.underscoredone.com/check
Checks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple Mail, and Yahoo. It looks up the BIMI settings the domain has published, checks the logo file follows the required format, checks any logo certificate is valid and unexpired, and confirms the domain has strict enough email protection turned on. Returns a clear pass or fail per domain, plus a plain list of what is broken when something fails.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
