As Featured In
Everything You Need in One Dashboard
iO™ DMARC covers every layer of email authentication, setup, monitoring, enforcement, and reporting, so you do not need five different tools.
Expert-Assisted Onboarding
Your initial setup is lead by a real person, not just an automated wizard. We walk you through DNS changes and verify everything is working before you go live.
Multi-Domain Support
Manage email authentication for every domain you own from a single dashboard. Add domains as you grow, each at $37/month.
Sender Discovery
See every service sending email on your behalf, even ones you did not know about. iO™ DMARC identifies senders from your DMARC reports and shows which are aligned and which are not.
Weekly Summary Reports
Get a plain-language email every week with your authentication status, compliance score, and any issues that need attention. No logging in required.
DNS Record Hosting
We host your SPF (via flattening), DKIM, BIMI, and MTA-STS records where supported, reducing the DNS changes you need to manage and eliminating propagation delays.
Compliance-Ready Reporting
Export authentication reports for cyber insurance renewals, compliance audits, and client questionnaires. Show auditors your domain is protected with real data, not just a checklist.
Change Monitoring and Alerts
iO™ DMARC watches your DNS records and alerts you when something changes, whether it is a record you modified intentionally or a third-party sender that updated their infrastructure.
Flat, Transparent Pricing
$37/month per domain. $150 one-time professional setup. No tiers, no feature gating, no surprise invoices. Every feature is included for every customer.

Check Your Email Authentication Right Now
From First Scan to Full Enforcement in Four Steps
iO™ DMARC walks you through every stage of email authentication, with expert support at every step.
Assess and Align
See where every protocol stands
Run a full domain scan to see where your SPF, DKIM, and DMARC records stand. iO™ DMARC identifies every sending source and shows you exactly what is aligned, what is missing, and what needs to change.
Configure
Guided, one-click DNS setup
Set up or fix your DNS records with guided, one-click configuration. iO™ DMARC generates the exact TXT records you need and tells you where to add them. No DNS expertise required. Your onboarding specialist reviews everything before you go live.
Monitor and Tune
Readable dashboards, weekly summaries
Once your records are live, iO™ DMARC collects aggregate and forensic DMARC reports and translates them into readable dashboards. Discover unauthorized senders, track alignment rates, and get weekly summaries so you always know where you stand.
Enforce
From p=none to p=reject, safely
When your authentication is solid, iO™ DMARC guides you through tightening your DMARC policy, from none to quarantine to reject. You will see exactly which senders are ready before each step, so you never accidentally block legitimate email.
Complete Email Authentication Management
See issues at a glance, apply guided fixes, and keep every protocol enforced. iO™ DMARC manages your full authentication stack from one dashboard.
SPF Management
One-click setup. Lookup counting. Include flattening.
Set up and maintain your SPF records with one-click configuration. iO™ DMARC flattens nested includes, tracks your DNS lookup count, and prevents the syntax errors and lookup overflows that silently break deliverability. When a third-party sender changes their infrastructure, you will know before it becomes a problem.
DKIM Management
Every selector, every sender, every key.
See every selector in one place, generate and rotate keys, and keep DKIM alignment solid across all your sending services. iO™ DMARC handles multi-sender environments where each service has its own selector, so nothing falls through the cracks.
DMARC Management
Guided setup. Readable reports. Safe enforcement.
Guided DMARC DNS setup ensures your RUA and RUF records are properly configured from day one. iO™ DMARC translates raw XML reports into plain-language dashboards with compliance scoring, sender discovery, and the data you need to move from p=none to p=reject with confidence.
BIMI Management
Your brand logo, right next to every authenticated email.
Display your brand logo next to every authenticated email. iO™ DMARC converts your logo to the required SVG Tiny PS format, hosts it for you, and can even host your Verified Mark Certificate (VMC), so setting up BIMI is as easy as uploading an image.
MTA-STS and TLS-RPT Management
Enforce encrypted delivery. Watch it with TLS reports.
Enforce encrypted email delivery and monitor it with TLS reporting. iO™ DMARC configures your MTA-STS policy and TLS-RPT records, hosts the required policy files, and parses incoming TLS reports so you know when encrypted connections fail, before your recipients do.
Blacklist Monitoring and Reporting
Catch listings the moment they happen. Get back to inboxing fast.
Stay ahead of every major email blocklist before a listing kills your deliverability. iO™ DMARC continuously checks your sending IPs and domains against the blocklists that matter (Spamhaus, Barracuda, SpamCop, SORBS, SURBL, URIBL, and more), alerts you the second something gets listed, and shows you exactly why you were listed and how to get delisted fast.

Check Your Full Email Authentication with iO™ DMARC
SPF is one piece of the puzzle. Use these tools to check the rest of your email authentication stack.
SPF Checker
Validate any domain's SPF record. See authorized senders, count DNS lookups, and flag syntax issues that could hurt deliverability.
DKIM Checker
Verify a domain's DKIM signature, key size, hash algorithm, and selectors. Confirm that outgoing emails are cryptographically signed.
DMARC Checker
Check any domain's DMARC policy and alignment settings. See whether authentication failures are being monitored, quarantined, or rejected.
BIMI Checker
See if a domain has BIMI configured to display its brand logo in supported inboxes. Check the BIMI record, logo format, and VMC status.
MTA-STS Checker
Check whether a domain enforces encrypted email delivery via MTA-STS. Verify the policy file, mode, and max age configuration.
TLS-RPT Checker
Verify a domain's TLS reporting setup. Confirm that encrypted delivery failures are being captured and reported.
