Why these are ungated
A tool behind an email form is a lead magnet, not a tool. These are meant to be used in the middle of doing the work, you should be able to land here from a search, get the number you need and leave without an account. Nothing you type is transmitted or stored.
Poststack is a social media management tool for agencies. If these are useful you might look at the product, but the tools do not require it and are not limited without it.
