I want to send reminders 45 days, 30 days, 21 days before the event start date. I have mentioned all those 3 in process builder. Please see the screenshot. The problem I am facing is if I create a task with only 21 days left to the event start, it triggers the 45 days and 30 days email alert too because it thinks the date has already passed, so it kind of triggers them. Is there any way system can only send email alerts for the upcoming reminder dates not the ones that have already been passed.
