Okay so I'm currently running a Subject Line A/B test for a newsletter I'm sending out. The winning factor is Click-Open Ratio. The winning subject line email is scheduled to send out next Tuesday. But after getting the analytics on the test back, I don't want the winning subject line to be used. Instead I want the losing subject line to go out. I've tried deleting the campaign all together and it won't let me. Is there a way I can edit the campaign at this point so that the winning subject line doesn't go out, and so I can chose what subject line goes out? If not, is there a way I can delete the campaign all together?
