[ By role ]

What this means for you

Choose your role for practical next steps.

IT / Mail Admin

Verify both DNS and signing

MailCamp documentation requires provider-side DKIM activation after record checks.

Next steps

  1. Confirm direct versus reseller SPF instructions.
  2. Use the account's issued selector and record type.
  3. Inspect the actual DKIM signature after activation.

CISO / SecOps

Review alignment changes narrowly

Removing strict SPF alignment changes a domain-wide control.

Next steps

  1. Inspect received identities before changing aspf.
  2. Require evidence for any claimed custom Return-Path feature.
  3. Document old sending permissions before retiring them.

Founder / Non-technical

Approve the final campaign identity

Combined mailing lists can produce sender settings that need their own review.

Next steps

  1. Name the owner of each campaign or automation.
  2. Confirm the final From and reply-to addresses.
  3. Keep a pause and recovery option for domain changes.

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.
