Frequently asked questions
Does DMARC stop lookalike domains?
No. DMARC protects your exact domain only, so lookalikes need monitoring and takedown.

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.
