Inviting People From Dashboard Sending Automated Emails To The

My question to any of you is how can I send an automated email to the people I invited thru the dashboard, I do have that invite plugin installed and in use, but I like the invite system where i can fill out peoples info and stuff, and wondering if there’s a plugin for automated email so when I invite someone from either filling out there info, or even that “Invite Friends” plugin where an email will grab the persons email addy and send them an email. Cause right now, I have to manually send each and everyone an email and it takes forever.
