    A policy that actually instructs receivers, which is more than most senders publish.

    keys published on 3 selectors

    A key existing is not the same as working. Read a real received header and check the d= value matches your before you call this done.

    google._domainkey (Google Workspace), k1._domainkey (Mailchimp), mandrill._domainkey (Mandrill)

    Part platform, part you

    The key is Mailchimp's to publish and it has. Whether it signs the domain in your is yours to confirm, and cannot show it — send one campaign to yourself and look for =pass header.d=deliveroo.co.uk in the Authentication-Results header.

    Receiving mail via Google Workspace

    Where you receive mail says nothing about where you send it. Marketing sends usually leave through a different platform entirely.

Where this comes from. Public DNS, and nothing else. We read the same TXT and MX records any mail server reads before accepting a message, on the days someone looked. There is no scan, no login, no mail, and no score here — only what was published and the date we saw it. Gaps are days we did not get a clean answer from a resolver, and we would rather leave those blank than guess at them.
