# Usage of the If/Switch Macros with the Advance Alert, Default Subject Field

It is possible to customize the subject line for alert email notification using the `if` or `switch` macros. For example, to set the subject line to “It is a warning!” in the case of a WARNING (notification level), you can set the subject line using the `switch` macro as follows:

`${switch ("${NotificationLevel}","Warning","It is a warning!","Critical","Down","Improved","Up","NA")}`

Once implemented, when a warning alert is triggered for the test, the notification in the inbox will have the subject line as “It is a warning!”.

Note: When using the `if` or `switch` macro with the email subject, they can only be used with the macros in the [Alert Email Macros](https://docs.catchpoint.com/docs/Alert-Email-Macros).

Following are screenshots of the subject and alert notification sent based on the above example:
