So the way it used to be , you would select the lists you wanted to send the campaigns to and then you would put a checkmark in the box by each list and click on ADD. Then it would show in the top and you would see and make sure you had the right ones going out. Then you would hit SEND. It would normally do a delay of 10 min (which for me was a bit long so I'm happy with the quicker send right now).
Once you hit send you would see a screen and it showed you what lists the campaign went to. This way if you screwed up you had time to quickly pause the scheduling and fix it. I send out campaigns to lists of 500, 700 etc so yeah, I don't need to do a mixup! And with this new fast send, there is no time to pause if I notice I mixed it up.
So when we are adding the lists to the campaign it needs to be the checkbox and the ADD button so we can see exactly what we are adding and and big confirmation before we hit that big red button! I've made that mistake before and there is no grief like having 500 people emailing you to tell you that you send them the wrong email! Now I am super careful and cautious and this new design makes it very stressful to ensure that it doesn't happen again. So dont' make me run over to MailChimp please because I prefer CC but I need to have fail safes when sending to make sure I'm sending to right lists.
