Yes. You can generate an extract of subscribers filtered by the source of their unsubscribe event by using the tracked unsubscribe target expression with a source field filter.

Prerequisites: This feature requires that unsubscribe events have been logged against subscriber profiles via the Taguchi custom tracking API, with a Subscriber Event Custom Field (e.g. source) capturing the unsubscribe source value. If this field does not appear in the target expression builder, ensure it has been created under Settings > Custom Fields with the field type set to Subscriber event.

Steps

1. Navigate to the Subscribers tab and click Extract Subscribers, or open any activity and click Extract Recipients in the top-left of the activity editor.

   This will bring up the subscriber extract window.

2. In the Target expression field, enter a tracked unsubscribe expression that filters by the unsubscribe source. For example:

   | Expression | Description | | ---------- | ----------- | | tracked unsubscribe source = "preference-centre" | Subscribers who unsubscribed via the preference centre | | tracked unsubscribe source = "sms-reply" | Subscribers who unsubscribed via SMS reply | | tracked unsubscribe source = "call-centre" | Subscribers who unsubscribed via the call centre | | tracked unsubscribe source = "preference-centre" last 30 days | Subscribers who unsubscribed via the preference centre in the last 30 days |

   Replace source with the name of your Subscriber Event Custom Field, and replace the quoted value with the unsubscribe source value you want to filter on.

3. Under Extract type, select Subscriber Profile.

4. Click Generate extract.

The extract will start generating. A notification will appear in the **Notifications tray** (top-right of the interface) once it is ready to download.
