Email Whitelisting via Script

I am looking for someone to create a script that automatically whitelist my "from address" when I'm sending emails to my subscribers. Once the user subscribes to my site via web form, the script should run, automatically adding my "from address" to their contact list thus allowing me to email them without it going to spam. It will need to add my "from address" to the 3 major ESPs - Gmail, Yahoo, and Outlook/Live.
