Split a list

Split a list to create multiple static lists with a percentage of the list's records. You can use split lists to test subsets of a list. For example, you can split a list of contacts that receive marketing materials and use the split lists to test different marketing campaigns.

To get individual samples of a list with a certain number or percentage of records, you can create a random sample instead.

1. In your HubSpot account, navigate to CRM > Lists.
2. Click the name of the list of which to create a sample.
3. In the top right, click Actions, then select Split list.
4. To distribute records equally across lists, toggle the switch on. If your source list won't split evenly, leftover records will be equally distributed across your splits.
   
   
5. To create custom splits:
   • Enter a name for the new list.
   • Enter the desired percentage of records for each list. The number of records will automatically populate so you can view the count breakdown. 
   • To add another split, click Add split. You can create up to 10 splits.
     
     
6. Click Create lists.
7. A pop-up will appear to confirm the new static lists were created. To navigate to a new list, click the list name. To close the pop-up and return to the source list, click Got it.
   

To track how many splits have been created from a list, you can review the source list's details. Learn more about editing or using lists.
