Signal Notifications Templates control the content of the emails and SMS messages HEAL sends. Each template uses placeholder variables that resolve to live values when the notification fires.
When notifications fire
There are two Lead Signal types: Early Warning and Problem. HEAL sends a notification when:
- A signal is created (status Open).
- A new service is added to the timeline (status Open).
- A signal is upgraded (status Upgraded).
- A signal is closed (status Closed).
- A new severe event is added to the timeline (status Open).
- Signal severity changes (status Open).
- A signal is open for long or open for too long (regular reminders, status Open).
You only get notifications for services in applications assigned to you.

Use any of these variables across the templates.
- Signal ID
- Signal Description (impact summary)
- Signal Type (Problem or Early Warning)

- Root Cause Services (can be multiple)

- Affected Applications (applications tagged to the affected services, not the signal’s primary application)
- Total Events Count (across the signal’s life)
- Latest Event Count (on this update)

Scenario walkthrough
Two users, two applications.
- Jack. Assigned to Application A1 (Travels) with services S1 (Travel Web), S2 (Hotels), S3 (Hotel Inventory), S4 (Bookings), and S5 (Booking DB).

Signal opens. S1 has transaction failures. Five events on S1. Latest event count is one. Status is Open. Jack gets the notification.
Signal update 1. Three events on S2 and two on S3. S2 and S3 join the timeline. Two more events on S1. Latest event count is three. Status is Open. Jack gets the notification.
Signal update 2. Four events on S4. S4 joins the timeline. Two more events on S1 and S2. Latest event count is four. S4 is part of A1 and A2. Status is Open. Jack and Joe both get the notification.
