I am not receiving emails
Try and switch your email method.
1. Go to your wordpress admin
2. Go to NEX-Forms->Global settings
3. Change the email method and test
If you do not receive emails from any method make sure form your hosting provider that mail() is enabled from the server's php.ini settings.
1. check you spam folder
2. Make sure that there are no proxy settings blocking the email (find out from you network administrator)
