How do I use Follow-up Messages?

When creating a new message, select the Followup message type... The first message is marked follow-up message #1 and has a few options that you'll want to pay attention to, Check for new connections every X number of days. (this will basically look for contacts with the tag set for the follow-up message in intervals that you set) 

Once you save that message and create another follow-up message, this one will be labeled Followup Message #2. There will be a different option, it will say Send after X number of days. (will send this message in an interval of days after the last message was sent) 

The Followup message becomes really powerful because after you've pushed your initial prospects through the funnel, to start new prospects in the same funnel, all you have to do is add a tag to that contact, then when the scan happens it'll automatically start them at message 1.
