Suggestion: it would have been nice to have the need to purchase this separately indicated alongside the Sitely app pricing on the site. It means that, for some people at least, Sitely is an $100-150 more than you expect to be paying. As far as I can tell, this isn’t anywhere on your website, just inside the app itself.
We don’t expect the vast majority of our customers to ever need this. That’s why it’s a not very publicized add-on.
For those that do need the extra features, and the complexity and ease of breaking your privacy, security and layout integrity, the option is there. We expect only people who will extract way more value than the cost will be interested. So the pricing isn’t a problem in this case.
