InfoPath Dev

Hi, I have a requirement where I am building workflows for a client in SP2013. I am using Infopath and Nintex. The client has a specific requirement that all end-user actions need to be handled from within the outlook email body context i.e. the Infopath form will be embedded within the email body from where each user within the worklfow will access the form and interact based on their actions. So my query is, 1) How to control the Views for each user within the Infopath form if its to be embedded within the Outlook email. 2) How to control the actions for the user interaction (submit, approve, reject, etc.) so as to ensure the workflow proceeds with its process cycle as expected. In the whole scenario, the end-user wont access the inofpath form in the web browser or the infopath client application. It will be accessed from within the Outlook email
