## Actions

### Segment-level Actions

You can open a segment directly by clicking its name. If you click anywhere else in the row, the segment is selected and a toolbar appears at the top of the page. The toolbar provides quick access to **Edit** and additional options under **More**.

| **Action** | **Description** |
| --- | --- |
| Edit | Opens the segment in edit mode. |
| View | Opens the segment in view mode. |
| Copy | Creates a copy of the selected segment. You must assign a unique name. |
| Calculate | Calculates how many contacts match the segment criteria. |
| Delete | Deletes the segment after confirmation. See [Delete Segments](/v1/docs/delete-segments). |
| Transfer | Adds the selected segment to a group. See [Add Segment to a Group](/v1/docs/add-a-segment-to-a-group). |
| Archive | Moves the segment to the archive. Archived segments can be viewed using the toggle below the table. See [Archive Segments](/v1/docs/archive-segments). |

### General Actions

Active vs. Archived Segments

At the top of the overview, you can switch between **Active Segments** and **Archived Segments**.

The list updates after a short loading period.

| **Action** | **Description** |
| --- | --- |
| Create | Opens a window to create a new segment. |
| Delete (Mass Deletion) | The trash can icon at the bottom of the page opens **Mass Segment Deletion**, which allows you to delete multiple segments based on selected criteria. Segments currently in use are not deleted and will be marked as “Failed”. See Delete Segments. |
