Subscribers added with a status of "Unsubscribed"
|Knowledge Article Number||000214351|
When sending using the Salesforce Marketing Cloud Connector, records are added to the Marketing Cloud for the recipients in order to manage the subscriber's status. It's possible for an Unsubscribed subscriber to be added.
This happens when the Email Opt Out checkbox is checked on the Salesforce record that's included in the target for a Send. Even though the subscriber is never sent an email, there's a record created within the Marketing Cloud with a status of "Unsubscribed."
If the record should not be opted out then the "Resubscribe" button can be used on the Contact or Lead record to make the record active within the Marketing Cloud.
