Subject Line, Subject Line Subject Lines and Subject Line Tests

Subject lines are so interesting to me, because i would also argue that, if you get to a certain level of reply rate, who cares about your open rate? Right? I think opens can be taken somewhat with a grain of salt um, unless everything else isn't hitting the mark. If you're getting the right engagement and the right type of replis, don't be hard on your tcause, preo, pain.
