Pushover delivers an alert to your phone and desktop as a push notification. For teams who want something louder than a chat channel but do not need the per-message cost of SMS, it sits neatly in between.
Most escalations have a gap between "posted in a channel nobody is reading" and "woke someone with a text". This fills it.
A push notification surfaces on a locked phone, which a message in a busy channel does not.
With no per-message cost, you can afford to use it on monitors that would not justify a text.
If you are the whole on-call rota, this is often all the escalation you actually need.
Push notifications depend on a data connection. For the genuinely critical path, SMS or a phone call is more reliable.
Put it after a short wait so brief outages resolve themselves before your phone buzzes.
The default. The step fires once and resets on recovery rather than repeating throughout.
Connect Pushover, send a test, and wire it into your first flow.
