Back ASP.NET MVC View as HTML file for use in email template

Question

I am creating an application that will send user emails to end users.

I created an HTML template from which emails will be created.

I currently have a template populated with tags as placeholders for custom content ...

|Text-Placeholder|

I return the html file as a string to my CreateEMail method:

string html = System.IO.File.ReadAllText(Server.MapPath("~/EmailTemplates/emailTemplate.html"));

And then using String.Replace to replace in custom text / content

html = html.Replace("|Name-Placeholder|", username);

I am curious if there is a method that would allow me to create a template in the form of a RazorView, strictly typed as a ViewModel, which will model the user text / content and return the view as an HTML file or directly as a string to pass to my body property SMTPClient instance for sending to user?

Has anyone done something similar or similar?

Take a look at these libraries:

There is an ActionMailer. Inspired by Ruby ActionMailer.

        From = "[e-mail]";
        Subject = "Welcome to My Cool Site!";

as a small suggestion, instead of placeholders, use resources. you create a resource file, say, in the ~ / Content directory called EMail.resx and add your tokens to it. in a view, you can refer to them as follows: @EMail.Nameand @EMail.Address. the advantage is that if tomorrow you need to send mail in french, you will create EMail.fr.resx with all the tokens, and you will end
