[ By role ]

What this means for you

Choose your role for practical next steps.

IT / Mail Admin

Protect inbound mail routing

Listrak bounce handling belongs on its dedicated subdomain.

Next steps

  1. Do not change root MX for bounce handling.
  2. Apply the intended list branding.
  3. Verify DKIM activation with a controlled send.

CISO / SecOps

Separate branding from authentication

A branded link is useful but cannot prove aligned message authentication.

Next steps

  1. Inspect receiver results.
  2. Check all shared-domain senders before policy changes.
  3. Require list-level evidence and review.

Founder / Non-technical

Accept each brand separately

A multi-brand account can have list-specific sending and bounce identities.

Next steps

  1. Name the owner for each list.
  2. Approve the list-to-domain mapping.
  3. Keep campaign rollout conditional on test evidence.

Frequently asked questions

Is the Domain Alias also the bounce domain?

No. Listrak describes the alias for branded links and a separate bounce domain for delivery feedback.

Where should the bounce MX record be published?

At the dedicated bounce subdomain specified for the setup, never at the corporate root as a shortcut.

How do I avoid sending the audit message accidentally?

Inspect the branding audit at the confirmation stage and cancel that flow; conduct any authorized live test separately with a verified one-recipient filter.

Does dkim=pass alone prove DMARC passes?

No. Check signing-domain alignment with From or an aligned passing SPF result, plus the receiver’s DMARC outcome.

Should I replace the root SPF record with the bounce-domain example?

No. They authenticate different identities. Review the exact owner and preserve existing legitimate sending systems.

What remains unverified?

Tenant settings, live DNS, list-specific received-message identities, functional outcomes and human SME approval.

Enterprise provenance

Why top financial institutions and governments retired their email security dashboards.

Traditional email authentication platforms sell you a dashboard and ask your engineers to do the labour. In high-stakes environments, manual oversight means delayed enforcement, configuration drift and unmonitored shadow domains.

EmailAuth is the agentic email provenance platform. Our agents enforce p=reject, keep third-party senders aligned and move your domains to full RFC 9989 compliance, the new DMARC standard,, with human-in-the-loop auditability.
