There are two options: pro pricing and free signup. Signing up is as simple as possible. You just need to create a username and password. Once you get in and start using their tools, you’ll have to upgrade. The free account limits the number of forms you can use. When you hit that limit, you’re requested to upgrade. Otherwise your account won’t work.
There’s a better solution: Build out an automated email follow-up campaign that speaks directly to this objection. Any time you encounter this problem, you can send that prospect information that seems designed just for them. A multi-month educational campaign may reduce their content anxiety and nurture them toward a sale. Yes, it’s work up front, but once finished, this campaign will work for you always.
