Use Split into a list to take a smaller group from a segment. For example, save 200 contacts from Active subscribers as Spring launch – batch 1. Each split selects contacts at random. The new list is a fixed selection: it does not update when the segment changes.

​
Create the List

1

Open the segment menu

Go to Audience → Segments. Open the segment’s ⋯ menu and choose Split into a list.The segment menu with Split into a list

Choose the number and name

​
Send to the Rest Next Time

To send to the rest of Active subscribers after using Spring launch – batch 1:
  1. Open your next campaign’s Recipients step.
  2. Choose the Active subscribers segment as the audience.
  3. Under Do not send to, click Add → Lists and choose Spring launch – batch 1. Add any other earlier batch lists you want to skip.
The campaign excludes people in those lists and sends to the remaining eligible contacts in the segment. Campaign Recipients with Spring launch – batch 1 selected under Do not send to
A second split of the same segment can include contacts from the first split. Excluding a list only in the campaign skips those contacts; it does not replace them with others to fill your batch.
To create a fresh batch from Active subscribers, first edit that segment. Keep All conditions (AND), choose Add condition → List is not → Choose lists, select the earlier batch lists, and save. Then split the segment again.

​
If a Split Cannot Start

If the segment changes while the list is filling, the final list may contain fewer contacts than you requested. Check the saved count before using it. See Lists and Segments for more ways to group contacts, or Send Campaign to use your new list.
