How do respondents get their own answers via email?

@michaelo91 - welcome to the community. 

you have a couple of options: 

• if your plan permits, you can use the Settings - Notifications menu options to get to the Respondent Notifications which will send them an email with the results of the test (once you configure the email body to read how you would like.) 
• you can also connect your typeform to something like google sheets and use a merge template in Docs or Slides and an add-on called Document Studio to merge the data into the document, convert to pdf and attached to an email. 

there are several posts in the community on the topic.. 

cheers
