Free DMARC Monitoring
Monitor your domain's email authentication for free. Get a full dashboard, automatic DMARC report processing, security scoring, and alerts across all eight email security protocols. No credit card required.
What You Get for Free
Our free tier is not a limited trial. It is a production-ready monitoring setup that covers everything a small business needs.
2 Domains
Monitor your primary domain and a secondary or staging domain at no cost.
All 8 Protocol Checks
SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, DNSSEC, and DANE. The same checks paid plans get.
Security Score & Grade
A single score that tells you where you stand. Track improvements over time.
DMARC Report Processing
We receive and parse your DMARC aggregate reports automatically. See who sends email as your domain.
TLS-RPT Report Processing
Know when sending servers fail to establish encrypted connections to your mail servers.
Email Alerts
Get notified when your security score drops or a DNS change breaks your authentication.
Free DMARC Tools Compared
Several tools offer free DMARC features, but the scope varies widely. Here is how MailShield's free tier stacks up.
| Feature | MailShield Free | Postmark | Cloudflare | dmarcian |
|---|---|---|---|---|
| Dashboard | ||||
| Multi-protocol | ||||
| Report processing | ||||
| Alerts | ||||
| Business use | ||||
| Domains | 2 | 1 | Unlimited* | 1 |
Postmark DMARC: Free weekly email digests, but no dashboard or multi-protocol monitoring.
Cloudflare DMARC: Free for Cloudflare DNS customers only. DMARC-only, no other protocol checks.
dmarcian: Personal/non-commercial tier only. Business use requires a paid plan.
Other tools: Most competitors (Valimail, EasyDMARC, PowerDMARC) offer free trials only, not a permanent free tier.
Why Free Matters for Small Business
Small businesses are the most targeted by email spoofing and phishing attacks, yet they are the least likely to have DMARC configured. The reason is simple: most DMARC tools are built for enterprises with enterprise pricing to match.
Without DMARC monitoring, a small business has no way to know if someone is sending email pretending to be their domain. Their legitimate emails may land in spam, and they will never find out why. A single DNS misconfiguration can silently break delivery for weeks.
MailShield's free tier is designed to change that. It is not a stripped-down demo or a 14-day trial. It is a full monitoring setup that covers 2 domains with all 8 protocol checks, automatic report processing, security scoring, and email alerts. It is production-ready for business use, permanently free.
What Happens When You Outgrow Free
If you need more than 2 domains, additional team members, or higher email volume, paid plans start at €15/month (billed annually). You get the same protocol checks and monitoring, just with higher limits and additional features like notification channels, API access, and advanced reporting.
There is no pressure to upgrade. The free tier does not expire, and we will never remove features from it to push you toward a paid plan.
