🔴 DOWN Alert: {domain} — {reason} | A site becomes unreachable | Red list | Adds the detected cause to the subject — an HTTP status, a DNS failure, a timeout — so you can tell the fault apart without opening anything. The reason is dropped from the subject when the cause was not identified. |
🟢 Recovery: {domain} | A site that was down becomes reachable again | Green list | Filed under green rather than red, so your recovery notices can go somewhere different from your failure notices. |
{level}: {domain} | An SSL certificate crosses one of your thresholds | That level’s list | The level is spelled out in the subject — “Initial Alert: example.com”, “Warning Alert: …” or “Critical Alert: …”. Sent as a formatted email showing the expiry date and the days remaining, not just the banner text. |
🟢 Certificate Renewed: {domain} | A new certificate replaces one you were warned about | Green list | Filed under green, like a recovery, so the all-clear can go to different people from the warnings. Includes the new expiry date and issuer. |
🔴 Certificate Missing: {domain} | A site answers without a valid certificate | Red list | Sent once, alongside the push, with the certificate the app saw at the previous check. |
🔴 Certificate Error: {domain} | A certificate is broken rather than expiring — a name mismatch, bad chain, or untrusted issuer | Red list | The most detailed message the app sends. It probes the site on plain HTTP to tell you whether the server is still running, and includes a short list of the usual causes with fixes. |
| Integrity findings — five separate subjects, all to the red listDespite the orange markers on the push versions, every integrity email is sent to the red list — that is the only per-level control the settings have. Each carries the recorded details and a “what to do” paragraph naming the likely real-world cause. |
|---|
🔴 Monitoring Stalled: {domain} | Monitoring has stopped producing results for a site | Red list | |
🟠 Security Headers Weakened: {domain} | Browser-side security headers were removed or loosened | Red list | |
🟠 Page Content Changed: {domain} | A page that had been stable changed substantially | Red list | |
🟠 Site Responding Slowly: {domain} | A site became persistently far slower than its own normal | Red list | |
🔴 Domain Expiring: {domain} | A domain registration is approaching its expiry date | Red list | |
🔴 Beyond Site offline: {sites} not being checked | The device running the app loses its connection | Red list | Sent once per offline period rather than hourly. It opens with exactly the banner’s words, the same Before and Now and the same sentences, then explains what the gap means. This is the one alert whose meaning inverts the others: it is not saying your sites are down, it is saying the app can no longer see them. |
🔴 {type} Records Changed: {domain} | A watched DNS record changes | DNS list | Off by default: switch on DNS Email Alert in Alert Settings and give it its own recipients. One email per site per check lists every change with its records before and now, and says “DNS Records Changed” when several types changed. Orange instead of red when no change is significant. |
| None | A scheduled background check finishes | — | No email. The routine summary stays on the phone, which is what keeps a mailbox from filling with “all good” messages. |
