# Multi-Domain Segments

Multi-domain segments are segments that exist across two or more domains within your organization enabling the management and targeting of your audience across multiple properties.

## Segment List

The segment list page shows you all multi-domain segments that exist within your organization. The table includes the following columns:

* **Name**: The name of the multi-domain segment that will be shown on within each individual domain's segment list.
* **Estimated Reach**: The total number of subscribers across all of your domains that match the segment criteria.
* **Domains**: The number of domains that this multi-domain segment includes. Hovering over the text in each row will display a breakdown of estimate reach for each individual domain.
* **Created**: The date segment was created.

### Bulk Adding Domains

When you need to add domains to existing segments you can take advantage of the `Bulk Actions` dropdown on the segment list. Select one of more segments you want to add domains to and then choose `Add Domains` from the bulk actions dropdown.

From here you can choose one or more domains to add to the selected segments. Once you've selected the domains click `Submit` to complete the process.

## Segment Create & Update

Saving multi-domain segments works the same as creating or modifying [domain-level segments](/platform/segments.md). The only difference is the addition of a component that allows you to choose which domains will be attached to the segment.

Once the multi-domain segment is created it will be available to target from the both the [organization notification context](/platform/organizations/multi-domain-notifications.md) as well as when creating a notification on an individual domain.

You can add or remove domains from the segment at any time. When removing a domain from the segment the segment will be archived within the individual domain.
