Hi @Sudhir Bhatt thanks for dropping by the community! This is a great question. 

We don’t have an option to import contacts and emails into Typeform, but you can pass your respondent’s information into the form through hidden fields an use another service, such as Mailchimp, to send the form to them via email. 

You would want to setup a process like this to pass in the respondent’s information. Does this help a bit?
