First blocker
Authentication policy cannot be verified before launch.
Three silent failures can turn a technical gap into a delayed launch, a bad client handoff, or an avoidable incident.
SPF crosses 10 DNS lookups or DMARC is missing.
Receivers can reject or distrust mail while the sending tool still reports a successful send.
The branded tracking hostname resolves, but its certificate is expired or mismatched.
Links can show a browser warning and a client launch can fail after approval.
PTR, forward DNS, HELO, and the live SMTP banner point at different identities.
The egress path looks inconsistent even when domain authentication passes.
The workflow stays attached to evidence from diagnosis through repair.
Enter one sending domain. The free check reads public DNS in your browser.
See Ready, Needs Fix, or Do Not Launch with the first source-backed action.
Rerun the same evidence after the DNS or infrastructure change.
Create a client-ready signoff or keep the approved baseline under recurring checks.

There are no invented testimonials or outcome metrics here. Open the sample report to inspect the verdict, evidence, fixes, and share format. Read the methodology to see how Unknown and conditional checks are handled.
Start with one domain. Pay when the decision needs to become signoff or an operating control.

Each asset runs only its applicable checks. Conditional checks run only when the required evidence is present.
No. OutboundQA checks visible infrastructure readiness. It does not guarantee inbox placement, and it keeps placement evidence separate from infrastructure evidence.
It checks public MX, SPF, and DMARC records for one sending domain. DKIM, tracking SSL, SMTP identity, inbox settings, and conditional history require more input or a full workspace run.
No. The free check reads public DNS. A full workspace can be defined with asset details or a CSV without mailbox passwords or a sending-platform API key.
Unknown means the available evidence cannot support a decision. OutboundQA names the missing evidence and the next check instead of treating uncertainty as a pass.
Use a Launch Report when a client or internal owner needs a shareable signoff for one launch. Use Continuous QA when approved infrastructure needs recurring checks and drift alerts.
One domain. Three public DNS checks. One first action you can verify.
