Protect every Klaviyo send

Stop silent email failures.
Lock down your DKIM, DMARC, SPF & BIMI.

DMARC Protector continuously validates your DNS authentication records against every campaign and flow you send. We catch misconfigurations before inbox providers do.

Monitors DKIM, DMARC, SPF & BIMI on every send Detects spoofing & shadow sending Built specifically for Klaviyo senders

We’ll review your current records, highlight issues, and send a plain-English summary.

How it works

Fix your DNS once. Monitor it forever.

Deliverability issues usually start in DNS, not in Klaviyo. We help you set up DKIM, DMARC, SPF, and BIMI correctly and then watch them continuously as you send campaigns, flows, and transactional emails.

1 Setup & Baseline

We audit your domains & senders

We map every domain and subdomain used in Klaviyo: from your primary brand domain to dedicated tracking or transactional domains. Then we pull current DNS records and build a baseline of what inbox providers see today.

  • Inventory of sending domains
  • Snapshot of existing records
  • Identification of misconfigurations
2 Configuration & Alignment

We help you configure the right records

You get clean, copy-paste DNS records written in plain English, plus guidance on alignment so your Klaviyo traffic passes modern DMARC checks.

  • SPF built to avoid lookup limits
  • DKIM selectors aligned to your from domain
  • DMARC tuned (monitor → quarantine → reject)
3 Continuous Monitoring

We watch every send for drift & abuse

DNS doesn’t stay still. New tools, ESPs, and internal changes can quietly break your setup. DMARC Protector tracks your DNS and DMARC reports and alerts you when something looks off.

  • Notification when a record changes
  • Alerts on new or suspicious senders
  • Detection of spoofing attempts
Email authentication basics

DKIM, DMARC, SPF & BIMI explained

If you use Klaviyo, these four DNS records decide whether inbox providers trust you. Here’s what each one does and why it matters.

SPF: Sender Policy Framework

“Who is allowed to send?”

SPF is a DNS record that says, “Only these servers are allowed to send email as yourdomain.com.” When an email arrives, the receiving server checks the IP or sending service against this list.

yourdomain.com. TXT "v=spf1 include:email.your-esp.com ~all"

How we help: we consolidate duplicate records and keep your SPF under technical limits.

DKIM: DomainKeys Identified Mail

“Did this email get tampered with?”

DKIM adds a cryptographic signature to each email. Your DNS holds the public key, and the sending service (like Klaviyo) holds the private key. The recipient checks whether the signature matches.

selector1._domainkey.yourdomain.com. TXT "v=DKIM1; p=..."

How we help: we verify that your Klaviyo DKIM selector exists and is aligned with your sending domain.

DMARC: Domain-based Message Auth...

“What should happen if SPF/DKIM fail?”

DMARC sits on top of SPF and DKIM. It tells inbox providers how strict to be (p=reject) and where to send reports about traffic claiming to be you.

_dmarc.yourdomain.com. TXT "v=DMARC1; p=reject; rua=..."

How we help: we guide you from “monitor-only” to “fully enforced” and analyze the incoming reports.

BIMI: Brand Indicators...

“Show your logo beside your email”

BIMI lets supported inboxes (like Gmail) display your logo next to your message in the inbox. It is a visual reward for having strong DMARC enforcement.

default._bimi.yourdomain.com. TXT "v=BIMI1; l=logo.svg"

How we help: we confirm your authentication meets BIMI requirements and help you publish the record.

DMARC indexing & alerting

Turn noisy DMARC XML into clear, actionable alerts.

DMARC generates machine-readable reports about every server sending as your domain. DMARC Protector indexes those reports, correlates them with your Klaviyo sending, and alerts you when something changes.

What we index from DMARC reports

We ingest aggregate DMARC reports and normalize them so you can see patterns over time, not just one-off spikes.

  • Source IPs and sending services claiming your domain
  • Pass/fail rates for SPF, DKIM, and alignment
  • Breakdown of traffic by “From” domain and subdomain
  • Which mailbox providers are enforcing your policy

Cases we alert you about

You choose the sensitivity level, and we’ll alert you when DMARC tells us something worth paying attention to.

  • A new IP or provider begins sending as your domain
  • Authentication failures spike for Klaviyo
  • Your DMARC, SPF, or DKIM record is changed or removed
  • Spoofing attempts gradually ramp up
Simple plans

Start with a health check. Grow into full monitoring.

Every engagement starts with a Klaviyo-specific deliverability health check. From there, you can stay on an advisory plan or move to continuous monitoring.

Health Check

A one-time assessment of your Klaviyo sending domains, DNS records, and current deliverability risk.

  • Review of DKIM, DMARC, SPF & BIMI records
  • Analysis of your sending domains used in Klaviyo
  • Risk report with prioritized fixes

Guided Setup

We work alongside your team (or your DNS admin) to implement the recommended records and alignment.

  • Hands-on help publishing correct DNS records
  • Safer rollout of DMARC enforcement
  • Verification of changes with real-world sending

Continuous Monitoring

Ongoing DMARC indexing, record monitoring, and alerting so you always know what’s happening in your email ecosystem.

  • Daily processing of DMARC aggregate reports
  • Alerts when records change or new senders appear
  • Monthly or quarterly summary reports

For exact pricing, share your sending volume and number of domains: [email protected].

Questions & next steps

FAQ & getting started

Do you need access to our Klaviyo account?

For the initial health check, we can usually work from read-only access or exported data about your sending domains. For ongoing monitoring, limited access can help us correlate DNS changes with specific campaigns and flows.

Can you work with our agency or internal IT/security team?

Yes. We’re used to acting as the translator between marketing outcomes (inbox placement) and technical standards (DNS, DMARC XML, etc.).

Will enforcing DMARC hurt our deliverability?

Enforced DMARC (p=reject) only hurts deliverability if your setup is broken. The whole point of DMARC Protector is to clean up SPF/DKIM alignment first, then move you into enforcement gradually.

What about transactional emails not sent from Klaviyo?

Most brands use multiple services. We can include non-Klaviyo senders in the audit and monitoring so your entire email footprint is consistent and protected.
