How do I send a white paper to someone who has completed a survey

Hi I hope someone can help. 

I am sending out a survey form which I have completed. What I am trying to do is once they have completed the survey that they are taken to a landing page where they can claim a White paper. The promise is complete the survey and I will send  a white paper as a thank you for taking the survey. Or is there a way in the survey form when they click submit they get a thankyou email with the white paper. I hope this make sense
