If you are pretty confident you will become a ClickFunnels customer after a free trial, I recommend signing up and using this Click Funnels pricing "trick" to save money.   On the Standard Package, you can save almost $200 over the year.  On the Etison Suite Package, you can save over $500 over the year.  I made this quick video explainer because after my first year on ClickFunnels, I wish I would have done this!  Check it out...
If you’re using an email service like Mailchimp, then you might be stumped on how to send content upgrades without adding subscribers to a gazillion lists and thereby paying for your subscribers multiple times. LeadPages makes this a very simple fix.

For example, your first email or two might go out on the day they first signup, then one email per day might go out afterwards. How much of that will be story-based and how much will be pitches?
