<a href="//wordpress.org/plugins/ninja-forms/" rel="nofollow ugc">Ninja Forms</a> is a great WordPress plugin and this plugin makes it even greater!
If you’re using Ninja Forms for gathering data and one or more of textbox fields 
must be unique, this plugin is for you. The plugin is pretty straightforward to 
install, and has few settings only (language settings, basically).
Once installed, it will validate every submission to make sure the values for 
one or more fields are unique.
