Emails

Open up email.ex and you will see a list of functions that generate Swoosh email structs. Eg:
def confirm_register_email(email, url) do
  base_email()
  |> to(email)
  |> subject("Confirm instructions")
  |> render_body("confirm_register_email.html", %{url: url})
  |> premail()
end
If I run this function in IEX I can see the Swoosh struct:
An Swoosh.Email struct can be delivered to an email address by a Swoosh mailer (see mailer.ex). Eg:
  Remindly.Email.confirm_register_email(user.email, url)
  |> Remindly.Mailer.deliver()
So email.ex creates the Swoosh structs and the functions for actually delivering emails like the previous code example are in user_notifier.ex. Think of email.ex functions like view templates, and user_notifer.ex functions like controller actions. 
So the steps to creating a new email will be:
1.Create the function to generate a Swoosh struct in email.ex
2.Ensure it looks good by navigating to "http://localhost:4000/dev/emails" and creating a new action in email_testing_controller.ex that simply renders the html_body value of the struct
3.Create a new user_notifier.ex function for use in our application
