Sometimes its necessary to limit a campaign to a specific number of users/recipients no matter how big the segment is. In order to do that we created the Limiting-functionality in the campaign settings.
When choosing the segment for the campaign you have the option to limit it to a custom number, connected to a specifc user-trait. If no specific user-trait is needed for the use-case, its possible to simply use the xng.GlobalUserId since this trait exists for every single user, no matter if any other identifier exists.
Important:
- The limit is a campaign setting, but applies to every single message in a campaign separately, e.g. if there are two messages with a subsegment each, the limit will apply to both individually.
-
The Limit is not actually random! If the segment itself is static with always the same users, the limit result will also always include the same users. The way it works is that it checks the full segment user list and then chooses the first or last users of the list (depending on ASC or DESC)
