Free Monitoring & Email Alerts
Keep an eye on your SSL certificate expiry, IP blacklist status, a DNS record, or your email authentication records (SPF, DMARC, MTA-STS, TLS-RPT) - and get an email the moment something changes. No account, no password: just an email address and a link to manage or stop the monitor whenever you like.
Create a monitor
How it works
- Create a monitor. Pick what to watch and where to send alerts.
- Confirm by email. We send a one-click confirmation link. Monitoring only starts after you confirm (this protects against someone using your address).
- Get alerted on change. We check on your chosen schedule and email you only when something meaningful changes - an SSL certificate nearing expiry, an IP becoming blacklisted, or a DNS record value changing.
- Manage anytime. Every alert email includes a private link to view or delete the monitor. No account or password is ever required.
Privacy
We store only the email address you provide and the check you ask us to run. Alerts go only to that address. There are no accounts and no tracking of your monitors beyond what is needed to run the checks and send alerts.
How this tool works: This tool runs in your browser and on our server in real time. Depending on the tool, results are computed directly from the input you provide or retrieved from live, authoritative data sources at the moment you run a lookup. We do not sell your data, and your lookups are kept private — any history shown here is stored only on your device.
