Leads do not integrate
It did not work for me. I wanted to create/update/add new conversations with ninjaform submission. So like before, I am still doing this manually
Sync Ninjaform submission to HubSpot (create new HubSpot contact on ninja form submission)

Excellent Plugin!
This is such a professional plugin and integrates so seamlessly. I'm anxious about some of the features being worked on. Specifically custom mapping from static values. That will be some decadent icing on the cake.
Capturing visitors to follow classes we teach
Quick setup, very professional appearance
Inability to tie hidden fields into the submission based on page. It would be easy to make the product interact with meta tags to target the content of the pages the user is viewing.
