Your domains, watched around the clock
Email security isn't a once-a-year audit - records change, certificates expire, domains get listed. DMARCER continuously re-checks every domain you manage, so problems surface in minutes, not months.
Re-check cycle – not on-demand, always
Controls watched on every domain
RFC-level compliance checks behind the score
Audits go stale the day after you run them
A point-in-time check tells you how a domain looked once. But SPF records get edited, DKIM keys rotate, MTA-STS certificates lapse, and IPs land on blocklists – constantly. The gap between “we checked” and “something changed” is where incidents live.
The full stack, re-checked continuously
Every domain is re-evaluated on a tight cycle against the complete set of email-authentication and transport-security controls. Nothing waits for someone to remember to look.
- SPF, DKIM and DMARC authentication
- MTA-STS and TLS-RPT transport security
- DNSSEC and blacklist / reputation status
- Registration, nameserver and lock-status changes
Drift detection, not just checking
DMARCER remembers how every record looked last time and tells the difference between “re-checked, still fine” and “this actually changed.” A real change – a weakened SPF, a dropped DMARC, a new blocklist entry – is what triggers an alert, so you’re notified about movement, not noise.
- Before / after on every monitored record
- Transient lookup blips don’t cause false alarms
- Parked domains auto-flip when they start sending
Built for one domain or ten thousand
