如何調用一個類或使用哪種模式？

Question

我有MailManager它有公共方法像什麼：

public MailMessage ConfirmationEmail(CommonTicketEmailViewModel viewModel) 
     { 
      var template = ReadTemplate("ConfirmationEmail.cshtml"); 
      string result = Razor.Parse(template, new { ConfirmationUrl = viewModel.Url, Token = viewModel.Code }); 

      var mailMessage = new MailMessage(); 
      mailMessage.Subject = "Confirmation E-mail"; 
      mailMessage.Body = result; 
      mailMessage.IsBodyHtml = true; 
      mailMessage.To.Add(viewModel.ToEmail); 

      return mailMessage; 
     } 

這個類只是MAILMESSAGE準備發送。請問這個班級有多正確？
