You can use message templates to customize notification messages for the contact point types.
To create a message tempplate:
1. In the Grafana menu, click the **Alerting** (bell) icon to open the Alerting page listing existing alerts.
2. In the Alerting page, click **Contact points** to open the page listing existing contact points.
3. From Alertmanager drop-down, select an external Alertmanager to create and manage templates for the external data source. Otherwise, keep the default option of Grafana.
The `define` tag in the Content section assigns the template name. This tag is optional, and when omitted, the template name is derived from the **Name** field. When both are specified, it is a best practice to ensure that they are the same.
