[Plugin: Newsletter] – Using form outside WordPress folder

Hello,

I´m testing to insert the subscription form outside WP Folder and for now it´s working fine. But I coudn´t find a way to get the response if the new subscription was inserted on database or not.

I´s using the code below to insert the subscription form ia a page (outside wordpress folder)

Here you can see the code: http://pastebin.com/vLzcFKFS
