The idea of using a funnel as a metaphor for Sales & Marketing processes in business really stems from the classic Marketing concept, AIDA. Attention, Interest, Desire, Action. These 4 elements generally describe how you build customer relationships, but they can also describe lots of other things too (like how to structure a really good sales letter or sales pitch).
Quite literally ClickFunnels is going to organize and arrange the two pages, the only two pages you need to build a massive email list, and they're going to show them to you right here. And they've got all these templates that you can choose from. As you can see over here, the final steps is quite literally the chronological or the stage-by-stage steps that your funnel will need to appear in and then you have these templates over here on the side that you can choose from at any given moment, that are really great. And they will sort them in converting order.
Now your marketing automation funnel is giving you a boost at every stage: It responded within five minutes of their first contact, and that helped get you the chance to make your pitch. Now, after the pitch, you're ready to stay in contact and respond to objections in a friendly, targeted way. (And if they love the pitch, automation can help you stay in close touch until closing.)
