Hello, let say that I set a campaign that start from a lead list and send one email after 5 days. What data does the system take into account for that? 5 days after what?  
  
I’m asking because I have a lead list that has grown very much (now 50.000) and I would like to build a campaign that send e-mails in some order, avoiding sending 50.000 e-mail/days.
