Open Supporters and switch to the Lists tab.
Lists are named groups of supporters (for example “Capital campaign 2026” or “Monthly donors”). Use them as the audience for Emails → Campaigns and as triggers for Automations.
You can:
Create a list and add supporters from the dashboard
Let a campaign auto-add donors when a gift completes (campaign settings)
Import or upsert contacts with the Supporters API (paid plans, write key)
A supporter can belong to more than one list. Removing someone from a list does not delete their donation history.
