## Availability

<table>

## Syntax

```
EndImpressionRegion(boolEndAllRegions)
```

The `EndImpressionRegion()` function has one parameter:

- `boolEndAllRegions` (boolean): If `true` or `1`, the function ends all previous impression regions. If `false`, the function only closes the preceding impression region. The default value is `false`.

## Usage

To call the function, determine whether you want to end all impression regions, or only the impression region that preceded it.

This example ends the preceding impression region only.

```
%%=EndImpressionRegion(false)=%%
```

This example ends all of the impression regions in the message.

```
%%=EndImpressionRegion(true)=%%
```

The system automatically ends all impression regions that aren’t explicitly closed by the end of the email.
