Take a look at the RazorEngine library, which does exactly what you want. I've used it before for email templates, and it works great.
You can just do something like this:
// Read in your template from anywhere (database, file system, etc.)
var bodyTemplate = GetEmailBodyTemplate();
// Substitute variables using Razor
var model = new { Name = "John Doe", OtherVar = "Hello!" };
var emailBody = Razor.Parse(bodytemplate, model);
// Send email
SendEmail(address, emailBody);
