MailChimp Integration - How to send an email

I have set up mailchimp integration and i would like to know if  I am  able to have a mailchimp email send to the person who completes my form? If so how?

Thanks! 

Yes, that is possible. In the integration, you have the option to send an Opt-in Email and  Welcome Email:

These emails are using your default MailChimp's email settings so if you need to customize them, you have to access your MC account and modify it here. The following MailChimp articles would help you configure the Forms and Response Emails:
