Create reusable groups of contacts. Add and remove members as your customer relationships change, while keeping preferences separate.
Audience membership and permission to send answer different questions.
Maya belongs to Harbor members and has an email address available for the campaign.
Membership identifies the cohort. Preferences and suppressions are checked when sending begins.
Alex remains in Harbor members for customer organization, but has opted out of marketing email.
Removing membership does not record an unsubscribe. Keep the customer’s sending preference authoritative.
Build audiences from the contacts you want to reach.
Paste addresses into an audience or assign audience IDs when importing contacts. Existing members retain their original join date when added again.
Public audiences use static membership. If your CRM or warehouse calculates a segment, synchronize both additions and removals. Changing a contact property alone does not recompute the list.
A channel label indicates a stored identifier, not consent or reachability. Removing a contact from one audience leaves the contact and other memberships intact.
Organize teams in workspaces, control API access, and trace changes through audit logs.
