From DNS Gaps to Inbox Confidence

Use your scan results to close SPF, DKIM, DMARC, and BIMI gaps before your next campaign send. We help you deploy clean authentication records, protect your sender identity, and improve inbox placement with a clear implementation plan.

Stop Guessing Where Your Emails Land

A single unauthorized domain config can silently tank your campaign ROI. Our deliverability scanner is a ruthless domain health check that validates the exact DNS records mailbox providers (like Gmail and Yahoo) use to trust your sender identity.

We run a deep dive on your SPF, DMARC, DKIM, and BIMI alignments in one seamless workflow. If a record is missing, fractured, or risky, we don't just alert you—we hand you the exact DNS-ready values to fix it instantly. Move from diagnosis to rock-solid infrastructure in minutes.

Why Domain Authentication is Non-Negotiable

Major inbox providers have aggressively tightened their authentication requirements. Hitting the primary inbox is no longer about just great copy—it's a technical mandate. Regular checks enforce sender integrity and maximize your campaign scale.

  • Bulletproof brand trust: Instantly shut down spoofing, phishing, and domain impersonation.
  • Maximized inbox placement: Flawless authentication is the fastest way to get your messages accepted by filtering algorithms.
  • Unshakeable performance: Stable sender reputations yield significantly higher open rates and consistent revenue.
  • Frictionless scaling: Hardened domains are a strict prerequisite for high-volume list growth and major product launches.

SPF Foundation Validation

Verify your Sender Policy Framework isn't bloated with risky include chains. We ensure your SPF record strictly authorizes your actual sending infrastructure, eliminating third-party vulnerabilities.

DMARC Policy Enforcement

Take complete control of rogue sends. We analyze your DMARC alignment to ensure you're safely transitioning from monitoring mode to a strict quarantine or reject policy without dropping legitimate mail.

DKIM Cryptographic Check

Sign your outbound messages with absolute authority. We validate your active DKIM selector coverage and key strength to guarantee recipients (and inbox algorithms) trust your message integrity.

BIMI Brand Presence

Dominate the inbox visually. We check your BIMI TXT readiness and logo specifications so you can proudly display your brand logo directly next to your messages in supporting email clients.

Domain Health Check & Deliverability FAQs

How frequently should I audit my domain health?

Audit your domain any time you onboard a new ESP, rotate encryption keys, adjust DNS settings, or prior to massive seasonal campaigns. A monthly health check is standard protocol for high-performance brands.

Is this scanner safe to use before I enforce a strict DMARC policy?

Absolutely. Our tool is critical for the monitoring phase (p=none). It ensures your SPF and DKIM foundations are flawlessly aligned before you confidently flip the switch to quarantine or reject policies.

Can the tool actually fix my missing records?

Yes. When the scanner detects a gap, it automatically surfaces a contextual generation wizard. You can input your parameters and instantly copy paste-ready, perfectly formatted TXT records directly to your DNS provider.

Will a perfect score guarantee my emails hit the inbox?

Perfect authentication is the heavy iron door of deliverability—it gets you inside the building. To reach the inbox consistently, you still need pristine list hygiene, hyper-relevant content, and engaged subscribers. Use this tool to solidify your technical foundation, then focus on your strategy.
