Reads the domain's DMARC record from public DNS, or the record of the organisational domain it inherits from, and says how strict it is and what is wrong with it, the DMARC checker on the OpenEmail website. stage is missing, invalid, monitor for p=none, quarantine or reject, and issues lists the problems written to be shown to a person.

Reads the domain's BIMI record, fetches the logo it names and checks the DMARC policy beside it, since inboxes draw a logo only at p=quarantine or p=reject, the BIMI checker on the OpenEmail website. status is present, partial when the record is there but something stops inboxes showing the logo, absent or invalid, and issues says why.

Checks the records a receiving mailbox reads before it trusts mail from the domain, the deliverability checker on the OpenEmail website: MX, SPF, DKIM at the selectors its mail provider uses, DMARC and BIMI. Each check says pass, warn, fail or absent with a verdict and notes, and score weighs them into 0 to 100, graded A to F.
