Your SPF record broke on Tuesday.
You found out on Friday.
We check your domain's SPF, DMARC, MX, and BIMI records every day and email you the moment anything changes, weakens, or disappears — before your customers notice.

How it works
1. Add your domain
Domain + alert address. Double opt-in — no one can subscribe your inbox to noise. A baseline snapshot is taken on confirmation.
2. Daily checks
Every day at 06:15 UTC we resolve your SPF, DMARC, MX, and BIMI records over Cloudflare DNS and diff them against yesterday's snapshot.
3. Alert on change
Something changed? You get a before/after diff within the hour. Nothing changed? We stay silent. Zero-noise monitoring.

Made for the person who owns “why is our email in spam?”
- ✓ Agencies managing client domains
- ✓ Teams that just migrated DNS or registrars
- ✓ Anyone who passed Google/Yahoo's 2024 sender requirements and wants to stay passing
- ✓ Brands with BIMI logos that must not silently break
FAQ
What exactly gets monitored?
Four DNS record families that control your email deliverability — SPF (root TXT), DMARC policy (_dmarc TXT), MX records, and BIMI (default._bimi TXT) — plus blocklist (DNSBL) checks of your mail servers' IPs against SpamCop, PSBL, and Barracuda. Checks run once a day via Cloudflare DNS-over-HTTPS.
What is DMARC report analysis?
When you activate a monitor you get a personal report address to add to your DMARC record's rua tag. Mailbox providers (Google, Microsoft, Yahoo…) then send us their aggregate reports about your domain, and your weekly digest shows the pass rate and — crucially — which sources are failing authentication or spoofing your domain. Free during beta.
When do I get alerted?
Instantly when something changes: a record is modified, added, or — the dangerous one — removed, with a before/after diff. Plus one optional weekly digest on Mondays summarizing all your domains ('all quiet' or what changed) — turn it off with one click and keep only the change alerts.
Why does this matter?
A deleted or broken SPF/DMARC record doesn't announce itself — your mail silently starts landing in spam, and most teams find out days later from customers. DNS records get broken by registrar migrations, well-meaning teammates, and expired includes all the time.
Is it really free?
Yes — the free tier covers up to 3 domains per email address, and stays free. Monitor Pro ($9/month) raises that to 10 domains with priority DMARC processing. Any existing Aarunya Pro license also unlocks Monitor Pro automatically.
Do you need access to my mail server or DNS account?
No. Monitoring is read-only public DNS resolution — the same lookups any mail server does. You give us nothing but a domain name and an alert address.
