How to send email from template using RazorEngine - asp.net-mvc

Question

I am trying to use a .cshtml template to send an email with RazorEngine. The documentation on their site shows how to use it with a string containing the razor syntax. How would I go about using it by loading a .cshtml file instead?
This is what I have
string templatePath = "~/Templates/InitialApplicationBody.cshtml";
var result = Engine.Razor.RunCompile(templatePath, "templateKey", null, viewModel);

From a MVC Controller, it's easy to generate HTML from a Razor view (CSHTML file).
I have successfully used code from the accepted answer to Render a view as a string, putting it in a base controller.
// Renders a Razor view, returning the HTML as a string
protected string RenderRazorViewToString<T>(string viewName, T model) where T : class
{
ViewData.Model = model;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
viewName);
var viewContext = new ViewContext(ControllerContext, viewResult.View,
ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}

The Mailzory project is a convenient choice for sending emails which have Razor templates. Mailzory uses RazorEngine behind the scene.
// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);
var email = new Email(template);
// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";
// send email
var task = email.SendAsync("mailzory#outlook.com", "subject");
task.Wait()
this project is hosted at Github. Also there is a nuget package available for Mailzory.
