See what is actually sending
Consolidate aggregate reports into readable sending sources, message volumes, authentication evidence, countries, and infrastructure roles.
Email authentication operations, made understandable
Turn email authentication data into a clear operating picture.
DMARC123 brings policy management, DNS validation, aggregate reporting, TLS reporting, geolocation, and sending-source intelligence together so teams can protect domains without stitching together raw XML, spreadsheets, and separate DNS tools.

Why DMARC123
Email authentication is easier to operate when policy, evidence, and action stay connected.
DMARC123 is designed for organizations that need to understand who is sending mail for their domains, whether those messages authenticate correctly, and which DNS or transport controls require attention.
Manage policy with context
Set DMARC, SPF, MTA-STS, and TLS reporting choices before generating the exact DNS records required for each domain.
Focus on what needs action
Separate compliant traffic, review items, threat or unknown sources, and forwarded mail instead of treating every report row the same.
Capabilities
One place to manage domains and investigate the evidence behind them.
Operational views are organized around the questions domain owners and administrators need to answer.
Compliance classification
Multi-select Compliant, Needs Review, Threat/Unknown, and Forwarded views with evidence-level drilldown.
Geolocation reporting
Map sending volume by country and compare the top locations for each compliance category.
Generated DNS setup
Produce registrar-ready CNAME and TXT records from saved policy rather than assembling records manually.
Public DNS validation
Compare published records and hosted MTA-STS policy behavior with the configuration DMARC123 expects.
Source intelligence
Use reverse DNS, infrastructure classification, country data, and cached blacklist evidence to investigate senders.
Account-secured access
Application administrators can oversee every account while account users see only the domains assigned to them.
How it works
A practical path from domain policy to ongoing monitoring.
DMARC123 keeps setup and reporting in the same product so the configuration you publish can be compared with the results you receive.
- 1
Define policy
Choose the DMARC, SPF, MTA-STS, and TLS reporting behavior appropriate for the domain.
- 2
Publish and validate DNS
Enter the generated records at the registrar, then verify the public result from DNS Validation.
- 3
Review real traffic
Use dashboards and reports to identify expected senders, configuration gaps, forwarding, and suspicious sources.
