Contact us form with Angularjs

iam creating a single page application with Angularjs and one of my pages is a “contact us” page, i hosted the application in a server and created an Email in the same server and have been trying to get my contact form to work for four days been haven’t been successful so my questions are:

  1. How does sending a mail from a website with my setup works exactly?

  2. Should i create an Alias and send the information from the contact form to it and then it sends it to my hotmail?

  3. Must i send the information from the contact form through the controller then to the php script? or can i just ignor the controller and send it directly to an email?

  4. should i simply use a Mailform in html and ignore all if the above?
