WHY MONITORING

A passing check today does not mean it will work tomorrow.

A free tool diagnoses what is wrong now. Monitoring tells you when it changes, breaks, and recovers.

FAQ

Does DomainPulse send test email?

No. Public SMTP tests stop before DATA and never change a domain configuration.

Do I need to own a domain to run a public check?

No. A public domain is enough for a one-time check. Monitoring requires an account.

Can DomainPulse guarantee email delivery?

No. It evaluates public technical signals and explains scanner limitations.

A CLEAR PATH

From a quick check to infrastructure control.

You do not need to understand every standard before the first check. DomainPulse helps you see the risk, understand the evidence and monitor only the domains that matter.

  1. 1
    Check a domain

    Enter a domain without creating an account and get one clear DNS, email, SMTP and TLS report.

  2. 2
    Understand priority

    See the confirmed issue and its impact first, then technical evidence and recommendations.

  3. 3
    Keep watch

    Save an important domain to receive separate incident and recovery notifications.

FOR TEAMS AND OPERATORS

A clear outcome for managers, evidence for engineers.

The overall result does not hide the details: reports retain discovered records, SMTP/TLS state and a history of material changes. Domain settings and data stay separated by workspace.
