# Alert message templates

You can change the text of your alerts. Use **tags** to add the details of the event.

## Where to change the text

| Where | What it changes |
| --- | --- |
| In a **channel**, under **Custom Message Template (optional)** | All alerts sent through this channel. |
| In a **rule**, with **Override the default message template for this rule** | Only alerts from this rule. This wins over the channel text. |

Leave the fields empty to use the default text.

Email channels have a **Subject** and a **Body**. Slack channels have one **Message**. Webhook channels send data, not text, so they have no template.

## The default email

- **Subject:** `Pastmark Alert: {{rule_name}}`
- **Body:** `{{message}}` and `{{count_line}}`

## Tags you can use

| Tag | What it shows |
| --- | --- |
| `{{rule_name}}` | The name of the alert rule. |
| `{{message}}` | The message of the event. |
| `{{severity}}` | The severity: info, warning, error, critical or debug. |
| `{{event_type}}` | The group of the event, for example `user` or `authentication`. |
| `{{action}}` | The action, for example `failed_login`. |
| `{{condition_type}}` | The kind of rule. |
| `{{timestamp}}` | When the event happened. |
| `{{count}}` | How many times the event happened. |
| `{{threshold}}` | The number of events the rule waits for. |
| `{{count_line}}` | A sentence like "Occurred 6 times (threshold: 6)." |
| `{{log_url}}` | A link to the event in your log. |
| `{{log_id}}` | The event ID. |
| `{{site_name}}` | Your site title. |
| `{{site_url}}` | Your site address. |
| `{{admin_email}}` | Your site's admin email. |

The list of tags is also under **Available Tags** in the form.

## Example

```
Subject: [{{site_name}}] {{rule_name}}

{{message}}
Severity: {{severity}}
See the event: {{log_url}}
```

Click **Preview** to see the text with example data before you save.

Always put `{{log_url}}` in your alerts. Then you can open the event with one click.
