include:_spf.salesforce.com · google._domainkey is Salesforce and Google Workspace, which is where staff read mail. It says nothing about where campaigns leave from, and a checker that counts it as your sending platform has told you about your inbox, not your list.

This is what your DNS authorises, not proof of what you send. A domain can authorise a platform it stopped paying for two years ago, which is why an include on its own is reported as permission rather than as use. Only a real message names the address that actually sent your campaign.

What this cannot see. DNS tells us what you have published, not what you actually send. It cannot read your consent records, your subject lines, or whether DKIM aligns on a real message — the three things that decide where a campaign lands. For those, send us a real campaign and we read them off the message itself.

Each of these answered an entry it is required to publish, and one it is required not to, before we believed anything it said about you. A list that fails either is reported as unanswered rather than as clean — because a blocklist that declines to reply looks exactly like one giving you the all-clear. How we choose them.
