Question: How do I get a list of subscribers from LianaMailer into a segment in LianaAutomation?

Create a new segment in Automation.

Select the channel: LianaMailer.

Define the event criteria
Choose the event criterion: Mailing List membership updated.

Add conditions
Add the condition: Mailing List membership list name is [the name of the list you want].

Add another condition: Mailing List membership status is Subscriber.

This way, all current subscribers from the selected LianaMailer list will be added to the segment.

The last checkbox means that the automation will always check the subscriber’s most recent status.
If a person has unsubscribed or has been removed from the list, they will no longer be included in the segment.

Save the segment.
