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

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

The BeginImpressionRegion() function has one parameter:

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

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

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.
