Looking for feedback on Leeflets

I've been working on something new (https://leeflets.com) for the past 6 months that allows people to create "single-page" websites for all kinds of niche-specific things in about 5-10 minutes (e.g. Newsletters, Profiles, Pay Me pages, Portfolios, etc.). Leeflets started as a side-project because I wanted something simple for my own profile/newsletter, but as I started sharing what I was up to, there was definite interest from others as well. I'm at a point now where Leeflets has existed publically for a few months and while I have nearly 100 paying customers, the growth definitely isn't even close to where it needs to be to continue full-time.

I'm looking for unbiased/honest/critical feedback from people I don't know because everyone I do know is telling me how great it is which generally is the equivalent of your Mom telling you how great something you did is. It's good to hear, but at the same time, I have to wonder if they really mean it, or if they're just trying to be supportive. If anyon's willing, please do "kick the tires" — you don't need to create an account to try it. Just create a page, customize it a bit and let me know what you think.
