Stop email spoofing, enforce DMARC, and monitor DNS health — all from one delightful dashboard. Built for teams that take their inbox seriously.
Trusted by security teams at companies worldwide
From DMARC enforcement to real-time alerts — six powerful features that work together beautifully.
Our scanner checks every critical DNS record, returns a 0–100 health score, and tells you exactly what to fix — no DNS expertise required.
MailShield ingests aggregate DMARC reports from every major provider and breaks down exactly which sources are passing, failing, or spoofing your domain.
No complex setup. No engineers required. Add your domain and MailShield handles everything automatically.
Here's exactly what happens after you sign up — and how each tool protects your domain.
Type your domain (e.g. yourcompany.com) on the dashboard. MailShield instantly resolves every relevant DNS record, scores your email security posture from 0–100, and tells you exactly what's missing.
MailShield gives you a unique rua=mailto: address. Add it to your DMARC TXT record (we show you exactly how). Within hours, Google, Microsoft, Yahoo and every other major mailbox provider start sending you daily reports — and we parse them automatically.
This is where MailShield earns its keep. The Sender / Vendor Discovery view shows every IP and service that has ever sent mail using your domain — your CRM, your invoicing tool, your support platform, and any spoofers trying to impersonate you.
Once you can see all your legitimate senders, MailShield walks you from p=none → p=quarantine → p=reject. We tell you exactly when it's safe to upgrade, and warn you if a legitimate sender would break.
MailShield watches your DNS and DMARC streams 24/7. The moment a record changes, an unauthorised sender appears, or your pass rate dips, you get a notification — by email, Slack webhook, or both.
Every week MailShield emails you a one-page Executive PDF: total messages protected, spoof attempts blocked, top senders, current health score, and the trend versus last week. Forward it to your CTO, your client, or your compliance team — done.
See your first DMARC reports inside 24 hours.
