Monitoring
A one-time check tells you where things stand today. Email configuration changes — a DNS provider migration, an expired record, a new sending service someone added without telling you — and a clean result can quietly go stale. Monitoring re-checks a verified domain on a schedule and alerts you when something changes.
What monitoring adds
- Scheduled re-checks (daily on the free tier, more frequently on paid tiers).
- Email alerts when a finding changes — not just a repeat of the same report.
- History of past results for a verified domain.
- On Pro and Agency: DMARC aggregate-report analytics, showing known and unknown senders observed over time — see DMARC reports.
Verification required
Monitoring, history and DMARC report analytics require proving control of the domain (a DNS TXT challenge) before they unlock — the anonymous check never requires this.
