  • Looks fine

    present with p=reject

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

    v=DMARC1; p=reject; fo=1; rua=mailto:dmarc_rua@emaildefense.proofpoint.com; ruf=mailto:dmarc_ruf@emaildefense.proofpoint.com

    From DMARC p=none is monitoring, not enforcementSee what this looks like →

  • Context

    No key found on the selectors we know

    This is inconclusive, not a failure. selectors cannot be listed from , so we probed the common ones for Klaviyo, Google, Microsoft, Mailchimp, SendGrid and Postmark. A custom selector will not show up here.

    From DKIM passing is not DKIM alignedSee what this looks like →

  • Context

    MX records present

    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.
