This plugin does exactly what it says. If you want very basic go with the FREE one. But if you want more functions, and great support from Anssi, and develop it further then please don't hesitate to go PRO. The price you pay is fully worth and more. I believe he will add more functions to this as he continues to build it, and we can support with valid ideas from us. The plugin it self is simple, elegant and does what its supposed to. I had an issue with SEND MESSAGE function, which Anssi explained was due to how my Wordpress mail was setup, with the default being php mail. I am not an expert in coding and figuring out back-end issues, but he sent an example link and how to fix it with a SMTP out going e-mail set up and it worked beautifully! He continued to fix few small issues and it works perfectly on my site!
