# BeginImpressionRegion()

Denotes the beginning of a region to track with impression tracking.

**note:** Impression regions are only supported in outbound messages. CloudPages don't support impression regions.

## Syntax

```
BeginImpressionRegion(regionName)
```

The `BeginImpressionRegion()` function has one parameter:

- `regionName` (string): Required. The name to assign to the impression region.

## Usage

To call this function, specify a name for the impression region.

```
%%=BeginImpressionRegion("Header")=%%
```

The system begins an impression tracking region called "Header." The function has no output.

Use the `EndImpressionRegion()` function to close the impression region. If the impression region isn’t closed by the end of the email, the system closes it for you automatically.
