What we actually do
DMARC Engine is a hosted email-authentication platform. Customers delegate their DNS to us once, and from then on we host and keep their DMARC, SPF, DKIM, MTA-STS, TLS-RPT and BIMI records correct and aligned as their sending changes. Where a customer wants it, we also run the done-for-you rollout: we ingest their aggregate reports, watch the live traffic, and take the policy from p=none through quarantine to enforced p=reject on a monitored schedule, with no email outage.
That is the important thing to know about the writing on this site: the people producing it are the same people who provision these records in production and read the reports that come back. When a guide says a particular provider trips over SPF flattening, or that a forwarding path breaks DKIM alignment, it is because we have watched it happen in real report data, not because we read it somewhere else.
Where the expertise comes from
Email authentication is a small, deep field. The specifications, RFC 7489 for DMARC, RFC 7208 for SPF and RFC 6376 for DKIM, are public, but the hard-won part is what happens when real senders meet them: the third-party tool that was never aligned, the subdomain nobody remembered, the reject policy that silently bounced a department's invoices. Our day-to-day work is exactly that gap between the specification and live mail, across many domains and providers at once, which is what our guides, glossary and free tools are built from.
How we write, and what we will not claim
We hold our own content to the same standard we hold our product. Guides are written in British English and reviewed for accuracy before they go out. We try to be genuinely useful rather than exhaustive, and to say when something does not help: DMARC stops exact-domain spoofing, for example, but it does nothing about lookalike domains or display-name tricks, and we say so plainly. We do not promise guaranteed protection or perfect deliverability, because no honest vendor can. If a page ever reads like it is overselling, that is a bug, and you can tell us.
