this may seem like a silly question, but I copied a previous mailing and it copied the campaign from that mailing. Now I can't figure out how to remove that campaign from my new mailing?
You can update the campaign for the mailing id 123 via one of the below method
- Run SQL code
UPDATE civicrm_mailing SET campaign_id = NULL WHERE id=123;
- API 3 explorer - Navigate to CiviCRM >> Support >> Developer >> API Explorer v3
