Everylayerofemaildeliverability.
Infraova runs 25 checks on every domain catching the issues that kill deliverability before your clients ever see them.

SPF Monitoring
CatchSPFfailuresbeforetheybreakauthentication.
SPF (Sender Policy Framework) tells receiving mail servers which IP addresses are authorized to send email on behalf of your domain. A misconfigured SPF record too permissive, too strict, or exceeding the 10-lookup limit causes authentication failures that hurt deliverability across every client using that domain.
Outcome
Stop SPF failures from silently tanking client deliverability.
v=spf1 include:_spf.google.com include:sendgrid.net ~all
DKIM Monitoring
Confirmsigningkeysarepublishedandvalid.
DKIM lets a sending domain attach a cryptographic signature to outgoing email. Receiving servers use the public key published in DNS to verify the signature. Rotated keys, deleted records, or short key lengths break this verification silently and most agencies only find out when deliverability drops.
Outcome
Never miss a rotated or deleted DKIM key again.
DMARC Monitoring
Trackpolicystrengthandcatchweakconfigurations.
DMARC builds on SPF and DKIM to give domain owners control over what happens when authentication fails. But a DMARC policy set to p=none does nothing it only reports, it doesn't protect. Many domains sit at p=none indefinitely because nobody notices.
Outcome
Move every client domain from p=none to enforcement.
SPF Enforcement
DetectweakSPFendingsthatletunauthorizedsendersthrough.
An SPF record is only as strong as its final enforcement mechanism. ~all (soft fail) marks unauthorized senders but still delivers their mail. +all (pass all) lets anyone on the internet send as your domain.
Outcome
Ensure every SPF record actually rejects unauthorized senders.
Current record ending
DMARC Coverage
FlagpartialDMARCenforcementbeforeitcreatesafalsesenseofsecurity.
The DMARC pct= tag controls what percentage of messages the stated policy is applied to. A domain with p=reject; pct=10 is only rejecting 10% of unauthorized mail the other 90% gets through.
Outcome
Ensure DMARC policy applies to 100% of mail, not a fraction.
Subdomain DMARC
Checkwhethersubdomainpolicyissetorinheritingaweakparent.
Subdomains inherit the parent DMARC policy unless an explicit subdomain policy (sp=) is set. If the parent domain is at p=none, every subdomain is effectively unprotected too even if the main domain is on its way to enforcement.
Outcome
Close the subdomain gap in DMARC coverage.
Blacklist Monitoring
KnowthemomentaclientdomainorIPgetslisted.
A blacklist entry can appear overnight and cause immediate deliverability damage before anyone notices. By the time a client calls to say their open rates dropped, the entry may have been there for days. Infraova checks against major blocklists continuously.
Outcome
Catch blacklist entries in minutes, not days.
DNS Change Detection
LogeveryDNSchangesoyoucantraceproblemstotheirroot.
Most deliverability incidents have a DNS change at their root a record edited during a migration, a TTL change nobody documented, an MX record quietly updated by a hosting provider. Without a change log, tracing the incident means guesswork.
Outcome
Trace any deliverability incident back to its root cause.
MX Records
Validatemailexchangerecordsarepresentandresolving.
MX records tell the internet where to deliver email for a domain. Missing, misconfigured, or non-resolving MX records mean inbound email bounces often silently. Agencies frequently inherit domains where MX records were set up years ago and never audited.
Outcome
Catch MX misconfigurations before inbound mail fails.
SSL Certificates
Trackcertificatevalidityandexpiryacrosseverysendingdomain.
An expired SSL certificate on a client's sending domain triggers browser security warnings that destroy trust instantly. Most agencies manage enough domains that manual expiry tracking is unreliable.
Outcome
Never let a client SSL certificate expire unnoticed.
Domain Expiry
Alertbeforeaclientdomainlapses.
A lapsed domain is one of the most avoidable disasters in email infrastructure and one of the most damaging. When a domain expires, email stops, the website goes dark, and in worst cases the domain gets picked up by someone else.
Outcome
Prevent the most avoidable client infrastructure failure.
PTR / Reverse DNS
ConfirmreverseDNSrecordsmatchthesendinghostname.
PTR records map an IP address back to a hostname. Many receiving mail servers check that the PTR record for a sending IP matches the hostname used in the SMTP greeting a mismatch is a common reason for messages being flagged or rejected.
Outcome
Eliminate a common and overlooked rejection cause.
Null MX
Signalthatnon-sendingdomainsacceptnomail.
RFC 7505 defines the null MX record as the correct way to signal that a domain does not accept inbound email. Without it, sending servers attempt SMTP delivery and queue messages indefinitely when they get no response.
Outcome
Eliminate pointless delivery attempts to non-mail domains.
MTA-STS
EnforceTLSoninboundmailtopreventdowngradeattacks.
MTA-STS lets a domain publish a policy that requires sending servers to use TLS when delivering inbound mail. Without it, an attacker can downgrade a TLS connection to plaintext and intercept email in transit.
Outcome
Protect inbound mail from interception and downgrade attacks.
TLS-RPT
EnableTLSfailurereportingsodeliveryproblemsarevisible.
TLS-RPT lets remote mail servers report TLS negotiation failures back to your domain. Without a TLS-RPT record, you have no visibility into whether inbound TLS connections are failing.
Outcome
Get visibility into TLS delivery failures before they compound.
BIMI
Verifybrandlogodisplayiscorrectlyconfigured.
BIMI lets domain owners publish a verified logo that appears next to their emails in supported mail clients like Gmail and Apple Mail. A missing or misconfigured BIMI record means the logo never shows.
Outcome
Ensure every client domain shows its logo in the inbox.
Spoofing Detection
Getalertedthemomentsomeoneimpersonatesaclientdomain.
Domain spoofing happens when an attacker sends email pretending to be one of your clients. DMARC aggregate reports contain forensic data about every message that claimed to be from your domain including unauthorized senders.
Outcome
Catch impersonation attacks before the client ever finds out.
DNSSEC
ProtectDNSrecordsfromtamperingandcachepoisoning.
Without DNSSEC, an attacker who controls DNS resolution can silently redirect MX records, modify SPF or DMARC, or intercept mail entirely. DNSSEC cryptographically signs your DNS records so resolvers can verify they have not been tampered with.
Outcome
Prevent DNS hijacking and MX record tampering.
CAA Records
RestrictwhichcertificateauthoritiescanissueTLScertificatesforyourdomain.
Without CAA records, any CA in the world can issue a certificate for your domain. CAA records prevent unauthorized certificate issuance before it happens.
Outcome
Prevent unauthorized TLS certificate issuance.
Nameserver Change
DetectunauthorizednameserverchangesbeforeattackerscontrolyourDNS.
A nameserver change is the highest-severity DNS event. If an attacker controls your nameservers, every other check becomes irrelevant - they can modify MX records, bypass SPF and DMARC, and intercept all mail.
Outcome
Catch DNS hijacking at the registrar level immediately.
Registrar Lock
Verifydomaintransferlockisenabledtopreventunauthorizedtransfers.
Registrar lock prevents unauthorized domain transfers without touching DNS or hosting. An unlocked domain can be stolen via social engineering at the registrar - no DNS access required.
Outcome
Prevent domain theft at the registrar level.
DANE/TLSA
CryptographicallybindTLScertificatestoyourMXhosts.
DANE uses TLSA records in DNS to bind TLS certificates to your MX hosts. When combined with DNSSEC, this eliminates reliance on Certificate Authorities for SMTP security and prevents TLS certificate substitution attacks.
Outcome
Eliminate CA dependency for SMTP TLS security.
SPF Record Length
CatchoversizedSPFrecordsbeforetheycausesilentauthenticationfailures.
SPF records that exceed the 255-byte DNS string limit are truncated or rejected by some resolvers. A truncated SPF record causes silent authentication failures with no obvious error.
Outcome
Prevent silent SPF failures from oversized records.
DKIM Key Strength
FlagweakDKIMkeysbeforetheycanbeexploited.
A 1024-bit DKIM key can be factored with enough compute. A compromised key lets attackers forge signed mail from your domain, bypassing DKIM checks entirely. 2048-bit is the current recommended minimum.
Outcome
Ensure all DKIM keys meet current security standards.
Health Scoring
Onenumberthattellsyouwhichdomainneedsattention.
Individual checks tell you what is broken. The health score tells you how serious the overall situation is. Infraova combines results from all 25 checks into a single 0-100 score per domain, weighted by severity.
Outcome
Turn 25 checks into one actionable priority signal.
