X2CRM version 8.0
A contact unsubscribes from a specific campaign category email, such as Marketing. The contact email address is then listed in the appropriate x2_list_items table as unsubscribed.
Create a new campaign with the Marketing category specified. Include the Contact that has unsubscribed in the contact list for the campaign.
Launch the campaign from the interface by clicking the 'Launch' button.
The result of this is the contact is not emailed because they have already unsubscribed. THIS IS THE EXPECTED RESULT
Same as above except schedule the campaign for some time in the future.
When the campaign fires, the result is the contact is emailed. UNEXPECTED RESULT
