Plugin Name: GF Upload to Email Attachment
Plugin URI: http://wpcms.ninja/
Description: Gravity Forms was built to be able to store all uploaded files to the server and email you a link. There are times that you need to have that file get attached to the notification email. You can now tick a checkbox in the notifications area to specify whether or not you want the file attached. If multiple files you are then able to have it attempt to zip before sending too. Also ability to delete files on email getting sent.
