Alerts when your site is actually down
Every check is confirmed from multiple regions before we post. No 3 a.m. channel storm over a blip that fixed itself.
Free on every plan
Slack alerts are included from the Free tier up — no SMS credits, no per-channel add-on, no calculator needed.
One place for every signal
Down, recovery, SSL/domain expiry, and cron-job failures all land in the same channel with the monitor name and timestamp.
How to set up Slack alerts
What you'll need: A Slack workspace you can authorize · A target channel
- 1
Connect your Slack workspace
In UptimeEye, open Notifications → New channel → Slack and authorize the workspace in one click. No webhook URLs to copy or paste.
- 2
Pick the channel
Choose the channel the alerts should post to — a dedicated #alerts channel or wherever your on-call already watches.
- 3
Attach it to what you monitor
Add the channel to any monitor, cron job, SSL check, or status page — on every plan, including Free. Send a test alert to confirm it lands where your team actually looks.
What triggers a Slack alert
Downtime & recovery
When a monitored website, API, or server goes down — confirmed from multiple regions — and again the moment it recovers.
SSL & domain expiry
Early warnings before a TLS certificate or domain expires, so you renew before it takes the site offline.
Cron & scheduled-task failures
Dead Man's Switch alerts when a scheduled job fails or misses its window, so silent background jobs never rot unnoticed.
Ways teams use it
- Route production downtime to #incidents and staging to #eng so the noise stays separate.
- Give a client their own channel with alerts for the sites you manage for them.
- Catch an expiring SSL certificate weeks before it takes the site down.
Slack monitoring FAQ
Do Slack alerts cost extra?
No. Slack notifications are included on every plan, including the free tier. There are no SMS-style credits and no per-channel add-on.
Will I get spammed with false alarms?
UptimeEye confirms a failure from multiple regions before it alerts, so a single flaky check from one location won't wake the channel. You also get a recovery message when the service comes back.
Can I send different monitors to different channels?
Yes. Create a Slack channel per team, client, or severity and attach each to the relevant monitors, cron jobs, and status pages.
What information is in each alert?
The monitor or task name, whether it went down or recovered, and the timestamp — enough to know what broke and when without leaving Slack.
