So for my trial subscription drip campaign there's 5 different email messages. The flowsteps have a wait step of after this date and time, send trial 2. Then a wait step of after this date and time, send trial 3, etc. and the last step just removes them from the flow and they get added to another list. So if someone missed the cut off period from when I activated the drip campaign, can I still add them, but I want them to receive the trial 1 email and not the other ones?
