You don’t need to be a DNS expert to get DMARC right

Let’s be real: Email authentication shouldn’t require a DNS certification. But if your team has ever stared down a confusing TXT record or scratched their heads at a DMARC failure report, you know how quickly things can get complicated.

Most IT and security professionals understand the “why” of DMARC. It protects your domain from being used in phishing attacks. It gives you visibility into who’s sending on your behalf. And when properly enforced, it’s one of the most effective ways to protect your brand’s email reputation.

But the “how”? That’s where things break down.

You need to understand SPF, DKIM, alignment, reporting, enforcement policies, and oh yeah, not break anything your marketing team or vendors are sending. No pressure.

Here’s the thing: You don’t need to be a DNS expert to get DMARC right. You just need a partner who is.

Why DMARC feels harder than it should

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is built on top of two other standards: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). That means you’re working with a chain of dependencies, and if something breaks upstream, DMARC will fail too.

Here are a few of the most common pain points teams face:

1. SPF’s 10 DNS lookup limit

SPF checks authorized senders by looking up DNS records. But it can’t handle more than 10 lookups per check. Go over that limit, and your legitimate email starts failing SPF, and by extension, DMARC.

Unfortunately, many companies unknowingly exceed that limit by adding multiple third-party email services (think: Salesforce, Marketo, Mailchimp, etc.). Each of these adds DNS lookups, and if you’re not actively managing the record, you’ll likely hit a wall.

2. DKIM complexity

DKIM works by cryptographically signing messages with a private key that matches a public key stored in your DNS. Sounds straightforward, but…

• Keys expire
• DNS records get deleted
• Vendors rotate keys without warning
• Misalignment issues tank authentication

DKIM is powerful, but fragile, and requires constant maintenance and upkeep.

3. Misconfigured DNS

DNS is challenging to manage and unforgiving.

One misplaced character, one wrong policy setting, and suddenly your email delivery tanks.

4. Confusing DMARC reports

You finally publish a DMARC policy, and now you’re getting XML reports from hundreds of inbox providers. What are you supposed to do with that? How are you supposed to read the DMARC report?

Unless you’ve built a parser or hired someone to interpret those reports, it’s all just noise.

Pro tip: Valimail Monitor makes it easy to read DMARC reports and provides them in a readable format that lists all the senders by name.

5. No in-house expertise

Not every team has a dedicated email security engineer, let alone someone who understands the nuances of DNS authentication. You’re already stretched thin, juggling endpoints, firewalls, and identity access management. DNS is one more thing on a growing to-do list.

You don’t need DNS expertise, you need a guide

• Discover all the third-party senders using your domain
• Resolve SPF and DKIM misalignment issues
• Avoid the 10 DNS lookup limit without custom scripting
• Read and act on DMARC reports in plain English
• Implement and enforce policies without breaking legitimate email

And here’s the part that sets us apart: our support team is with you every step of the way.

We don’t just toss documentation your way and hope for the best. Our team of experts guides you through deployment, monitors your progress, flags risky configurations, and helps troubleshoot sender issues as they come up. And if you need extra support and care to manage your complex DNS infrastructure? You can upgrade to our Valicare support packages.

Think of it as having a DNS expert on speed dial, without needing to add headcount.

What getting DMARC right actually looks like

When DMARC is done right, it’s a game-changer.

• Your domain can’t be spoofed anymore — no more exact-domain impersonation phishing.
• Your customers and partners trust your email because it’s authenticated.
• You gain visibility into every sender using your domain — legitimate or otherwise.
• Your brand is protected, and your risk of business email compromise (BEC) drops significantly.

Plus, achieving DMARC enforcement shows regulators, customers, and leadership that you’re serious about email security, and that your domain isn’t the low-hanging fruit attackers love to exploit.

Valimail makes email authentication manageable 

Valimail was the first to offer hosted DMARC, and we’ve continued to lead by turning complex DNS authentication into something that’s actually manageable.

We don’t treat email authentication like a side feature — it’s our entire focus. We built our platform and support model specifically for security and IT professionals who need:

• Clear guidance without jargon
• Solutions (not just “tools”) that keep working after launch
• Confidence that their DNS records and senders are always aligned

You don’t need to write regex or manually parse DMARC XML to get results. You just need a partner who’s done this before, thousands of times.
