Your email lands in spam. The fix is one DNS record.

Check your domain, or send us one real email. You get the verdict, the reason in plain English, and the exact record to paste.

How it works

From the first scan to full protection, without guessing.

  1. 1 Scan

    Free

    Email, DNS and expiry checks and a grade, with a plain-English reason for every problem.

    FailPass
  2. 2 Fix

    Free

    The exact record to paste, built and checked by code. AI explains it, never writes it.

    Example: a domain with no DMARC
    v=DMARC1; p=none; np=reject
  3. 3 Monitor

    Paid

    Daily rescans and DMARC reports, and your website every 5 minutes. Alerts when the site goes down, a record changes, a lookalike domain appears or a certificate nears expiry.

    daily rescan → alert

  4. 4 Enforce

    Paid

    When your reports show every real sender passes, you get the stricter record. You publish every record yourself.

    none → quarantine → reject

Monitoring

The scan is free. Monitoring keeps you healthy.

Records drift silently, and the road to p=reject (receivers refuse mail forged in your name) takes weeks of evidence. Monitoring watches every day and hands you the next record when your reports say it's safe.

  • Your website checked every 5 minutes from five locations, with an email when it goes down and when it's back
  • Alerts: record changes, blacklist listings, domain & SSL expiry
  • Reports from Gmail, Outlook and others: who sends mail as you, and whether it passes
  • The next, stricter DMARC record as soon as your reports show it's safe
  • Or Automatic DMARC: add one CNAME once, then move to the next step with a click
  • Lookalike domains: names registered close to yours, scored daily
  • No per‑email fees · 12‑month history
