We would like to automate an email to send each day to those who had a certain activity exactly 20 days ago (in this case, their trial ended exactly 20 days ago, which throws them into a new lifecycle stage - so there is a data value change we can filter on).
As far as I can tell, there is not a way to do this with the filter constraints, as if I were to use an exact day (is) then I cannot automate it, and if I use "in past" then I include more than I want to. This is not something that we have time to develop - we need a fast fix. Long term, I would add this into the general communication flow and make use of wait steps, but we don't have time for that right now. Any suggestions, solutions, hacks?
