Why was a record unsubscribed?

Generally, an unsubscribe happens via Campaign Monitor. When a person receives an email, they can click to unsubscribe, or if you have a preference center, they can remove themselves. When our primary sync next runs, it will update Salesforce.

If you want to make a person unsubscribed via Salesforce, there are a few options:

1. On the subscriber list membership record, simply click the email opt-out.
2. Using flow or custom apex, you can use an invokable action to unsubscribe a record.
3. If you have enabled the email opt-out options via our general settings tab, this can also unsubscribe a record.

Note: Import wizards or subscriber rules can add a person to a subscriber list or set them to deleted if enabled. They won't, however, change the status to unsubscribed.
