I am trying to create a Zap that will trigger when a record reaches 45 days from a renewal date. My team sends Marketing materials to prospects that are 45 days away from contract renewal dates. Currently this is done by a Marketing specialist filtering an excel spreadsheet and then manually importing those emails to a list in our CRM. I would like to set up a zap that fires and sends those communications automatically once a prospect reaches 45 days from their contract renewal date. I imported the data from the excel sheet to a table in Zapier table. The question I have now is how do I set up the Zap to fire once the renewal date is 45 days out?
