Last reviewed: August 19, 2026Notification templates
Notification templates control how a notification is formatted before it’s sent. Alertmanager renders them at send time, after grouping, so a template describes a whole group of alerts rather than one.
This is different from templating a rule’s annotations, which the ruler does per alert instance during evaluation. Refer to Templates.
