DMARC Monitoring & Spoofing Alerts
Your emails reach inboxes until they don't.
DMARC reports arrive as gzipped XML that nobody reads. We parse them and alert you when something drifts.
No credit card required. Free tier monitors 1 domain. See pricing

Deliverability fails silently.
By the time a customer tells you their password reset went to spam, you've already lost emails. DMARC aggregate reports are the earliest signal that something is wrong with your domain's alignment, but they arrive as gzipped XML, and unless you're running a monitoring stack, you read zero of them.
Every ESP you use (Resend, Postmark, SendGrid) affects your DMARC alignment. Add a new marketing tool, misconfigure an SPF record, and alignment quietly drops. You won't see it until Google does.
Postmark charges $14 per domain per month for their DMARC monitor. If you run eight domains across your projects, that's $112 per month to know what you could know for $9. Self-hosting parsedmarc is the other option: a Saturday well spent learning what alignment_mode: relaxed means.

Parse
Every report arriving at your rua= address is fetched, decompressed, and parsed. Alignment tracked across SPF and DKIM for every sending source. You never touch the XML.
Summarize
Alignment percentage, message counts, and every sender organized by volume, flagged when unrecognized. Weekly or monthly, your choice.
Alert
When alignment drops, an unknown source appears, or your DMARC record changes, you get a direct alert. Most domains: fewer than one per week.
If your alignment is stable and your senders are recognized, you hear nothing. That's the point.
How it works
- 01
Sign up
Create a free account. No credit card required.
- 02
Add your domain
You get a dedicated inbound address:
d-<id>@in.dmarcdrift.com. Add it to your_dmarcTXT record as therua=value. We show you the exact record to set. - 03
Reports start flowing
Google, Yahoo, and Microsoft send aggregate reports to your address within 24–48 hours. We parse them, track alignment, and email you a digest. You do nothing.
Glance once. Move on.
All your domains in one view. Click into any row when an alert fires, review the sending source, and close the tab. Most weeks you never open it.

This isn't for you if…
- –You need a compliance audit trail or regulatory reporting.
- –You have a security team that handles email authentication.
- –You need BIMI setup support or logo-in-inbox certification.
- –You need multi-user workspaces or role-based team access.
For enterprise DMARC, dmarcian, easydmarc, and Valimail exist. They're good at what they do.
Simple pricing. Pays for itself the first time it catches something.
No per-domain fees. Most competitors charge $14 per domain. Solo covers 15 domains for $9 flat.
