# Segmentation of customers
The segmentator is used for e.g.:
* combining several groups into one new group,
* deleting from a group of contacts that are in another group,
* create a new group based on filters or percentage breakdown.
1. After logging into the panel, go to **Contacts** -> **Group List** and click -> **Group Segmentation**:
2. Name the newly created group, or select from the list the group already in the account on which you want to segment,
3. Select what operation you want to perform:
2. Specify the parameters of the operation.
3. In the example below, we combine two groups previously imported into the account (Test Group 2 and Test Group) into a new group called "New Test Group." With this operation, a new item will appear in the list of groups.
