Email authentication, done for you

Nothing dramatic happens when your DMARC is wrong.

"No bounce, no error — the email just quietly lands in spam, and nobody ever finds out." That's what a broken SPF, DKIM, or DMARC setup looks like from the outside. We find the exact record that's wrong, show you, and fix it.

dig TXT _dmarc.example.com
_dmarc.example.com. 3600 IN TXT "v=DMARC1; p=none; rua=mailto:reports@example.com"
# found on a real audit — domain name changed
p=none This only logs spoofed mail. It doesn't block anything — and it doesn't stop legitimate mail from silently landing in spam either.
What's actually broken

Three DNS records decide whether an inbox trusts your mail

None of this is exotic. It's three plain-text entries in your DNS, and most domains — even well-built, professionally designed ones — are missing at least one, or have it set wrong.

SPF

Sender Policy Framework

A DNS record listing which mail servers are allowed to send email as your domain. Receivers check the list; anything not on it is suspect.

DKIM

DomainKeys Identified Mail

A cryptographic signature attached to outgoing mail, checked against a public key in your DNS. It proves the message wasn't altered and really came from where it claims.

DMARC

The policy layer

Tells inboxes what to do when SPF or DKIM fail on mail claiming to be from your domain — and sends you reports on who's sending mail as you, authorized or not.

The most common finding is DMARC set to p=none — or no DMARC record at all. Either way, legitimate mail that fails authentication (a customer's inbox is picky, a forwarding rule mangles a header) can land in spam with no bounce and no error. Nobody notices until someone asks why an invoice never arrived.

Proof, not warnings

We don't tell you to worry. We show you the actual problem.

Most of this space sells on fear — vague "your business could be at risk" copy backed by a demo. What's actually worked, every time, is the opposite: find one real, specific, verifiable broken record on your own domain, and show it to you before asking for anything.

That's not just how we get a reply to a cold email. It's the whole approach. A generic warning is easy to ignore. Your own DMARC record set to p=none is not.

Illustrative example — not a real client

example.com  TXT  "v=spf1 include:_spf.example-esp.com ~all"

SPF exists, but DMARC is missing entirely — nothing tells receivers what to do when a spoofed message fails SPF, and nothing reports back on who's actually sending mail as this domain. That's the kind of specific, checkable thing we lead with, on your domain, not someone else's.

Why this is current, not hypothetical

Google and Yahoo already made this a requirement — not a best practice

Feb 2024

Google and Yahoo started requiring SPF, DKIM, and DMARC for anyone sending 5,000+ emails a day to Gmail or Yahoo addresses — with enforcement that's escalated since to outright rejection, not just a spam-folder risk.

2025

Microsoft added its own authentication requirements for Outlook, Hotmail, and Live.com addresses. The three biggest inbox providers now agree on this.

May 2026

DMARC itself got its first major standards update in a decade (RFC 9989). The guidance on what "done right" looks like just changed — see how it works.

If you send under 5,000 emails a day, none of this is technically mandatory for you yet. But the failure mode — mail quietly failing with no error — doesn't care about that threshold. It happens at any size.

Done for you, not another dashboard

A person does the work and tells you what changed

Most tools in this space hand you a dashboard and a pile of DMARC aggregate reports to interpret yourself. That's a real product category, and it's not what we do.

Here, a person reads your domain's actual setup, tells you what's wrong in plain language, and makes the fix — or hands you exactly what to paste, if you'd rather do it yourself. Most first findings turn around within 24 hours.

The usual approach
  • Sign up, connect your domain, wait for reports to accumulate
  • You read the aggregate XML reports and decide what they mean
  • You make the DNS changes yourself
  • Ongoing subscription, self-serve from here
Brillux
  • We check your domain and find the specific problem
  • You get a plain-language explanation, not a report to decode
  • We make the fix (or hand you exactly what to paste)
  • Staged, monitored rollout — not a one-time toggle
Low-pressure, on purpose
