Split A List

Splitting a list allows you to take an existing list and split it into smaller chunks (split groups). For example, you could take a list of 100k contacts and split into three sub-lists each containing a percentage of the original list (ListA: 50%, ListB 25%, and ListC 25%). Contacts from the original list will be randomly distributed onto the split groups.

About this task

You can split a list into 5 separate lists (splits), each with it's own random group of contacts from the original list.

Splitting A List

To split a list:

Procedure

  1. Go to Contacts > Lists.
  2. Click on the name of the list you want to split.
  3. Click Split.
  4. Optional: Change the internal list name if needed.
    By default, the Internal Name text box is pre-populated with the internal name of the original list. Any subsequent list splits will use the internal name specified here. For example, My List - Split A, where My List is the internal name.

    Changing the internal name on the list split page does not change the internal name assigned to the original list when it was created.

  5. Optional: Click in the Name text box for each list split group and change its name.
    This text will appear after the internal name used for the list split. For example, if you had the internal name Example List, and changed the Group A split name to Split Number One, the Group A split would show up (in tables, list pickers, etc.) as Example List - Split Number One
  6. Assign percentages for each list split group.
    You can split the original list up to five times. If you would like the list to be split into fewer than 5 groups, leave those percentage values at zero.
    Note: The list split percentages must add up to 100%. You can view the total split percentage on the right side of the page.
  7. Click Split.
