An email from them managed to get into my inbox today, so at least my mail filters don't consider the source as spammer. On the other hand, here's the Crunchbase profile of Mr Schroter: crunchbase.com/person/wil-schroter. It seems the CEO of the Fundable-Startups.co-Bizplan bundle doesn't update his Crunchbase profile.
They have a "Testimonials" page with a title saying "Featured Funded Companies," yet no company details are given. There are only the names of the founders they claim to have helped raise capital. I googled several of them yet couldn't find their companies.
Moreover, they claim to be featured on some of the most well-known media, but they don't give any URL--just a non-clickable image containing the logos of Entrepreneur, Forbes, Money, and the WSJ. And you can't just google "entrepreneur investr.com" because it gives you a plethora of irrelevant results.
After all, it might be fun to call them to see what they have to offer.
