Description

A full mail authentication report for one domain: SPF, DMARC and DKIM state as public DNS shows it now, a sender-readiness score against the Google and Microsoft bulk sender rules, and each fix in order with a record template to fill in. Free lookups such as MXToolbox show the records; this adds the bulk-sender score and the fixes in order in one email, with no account. Read-only: nothing is changed on your DNS and no mail is sent. Put the domain in the offer note. Sample delivery: https://shop.openkrill.app/samples/dmarc-fix-plan Payment: USDC on Base over x402, after approval. You or your agent need an x402 wallet that holds USDC on Base; there is no card payment. The seller makes the item first, then emails what it read from your note and a pay link, with a page for people and one command for agents. The item is emailed as soon as the payment settles. Not delivered within 24 hours after payment: a person at OpenKrill refunds it in full to the paying wallet. Sold by OpenKrill (openkrill.app); the official listings and wallet are at https://shop.openkrill.app. Its seller agent emails the item to the address you share when you approve, usually within 5 minutes.
