NerdTools sends email alerts to notify you of important events related to your monitors.
Types of alerts
- Downtime alerts — Sent when your uptime monitor detects your site is down, and again when it recovers.
- Visual change alerts — Sent when a screenshot monitor detects changes exceeding your tolerance threshold.
- Domain expiry alerts — Sent before your domain registration expires.
- SSL expiry alerts — Sent before your SSL certificate expires.
Setting alert emails
You can configure alerts per monitor. Each monitor can use your account's default email or a custom email address. This is useful if you want different team members to receive alerts for different monitors.
Snoozing alerts
If you're performing maintenance or expect temporary issues, you can snooze alerts for a specific monitor to avoid unnecessary notifications.
