Unsubscribing a contact from a list blocks emails for that list, but allows the contact to receive emails for other lists.
For example, if a contact no longer wants to receive promotional emails, but still wants to receive newletter emails, then they could be unsubscribed from the promotional list, but still subscribed to the newsletter list.
To unsubscribe a contact from a list:
- Open a contact
- Under the "List Subscriptions" section
- Next to the appropriate list, click "Subscribed"
- This will toggle the contact to "Unsubscribed" for the list
- Clicking "Unsubscribed" will toggle the contact back to "Subscribed" for the list
