Creating dynamic email templates using C# and Office Outlook

It is quite common for many applications to send automated email notifications. Couple of months ago, I have worked on improving our old email template format to make it more user friendly.

In this tutorial I will walk you though regarding how I took advantage of Microsoft Outlook to quickly generate custom email template and later using the html template for building an automated custom email application using C#.


  • Creating Templates: Using the rich text editor support  in Outlook create a nicely formatted email. Use placeholder text for the values you like to change dynamically based on your task completion status.

    To keep this tutorial simple, I have created a  simple table with placeholder text inside the third bracket [place holder text]. However, you can use anything supported by outlook editor.
Figure: Email Template

  • Getting HTML code: Send the created email to your own address. After that, open the sent email and right click to view source. It will display the HTML source of the email body with all the formatting you have made. Copy the HTML source to a separate file and save it as EmailTemplate.html

HTML Source of the email
C# Application
Create a C# Console application and add the  EmailTemplate.html file  to your project
  • Now in the  C# console application you can read all text from the HTML file and replace the placeholder content with the value of your corresponding variable.
    • For example, in the following code sample I am replacing the placeholder text in the HTML with my own value.
      private string GenerateEmailBody(JobLoadParam jlp)  
           string emailBody = string.Empty;  
             string strHTML = File.ReadAllText("EmailTemplate.html");  
             strHTML = strHTML                 
                     .Replace("[SourceFileName]", jlp.SourceFileName)  
                     .Replace("[SourceFileNetworkPath]", jlp.SourceFileNetworkPath)  
                     .Replace("[ExceptionFileName]", jlp.ExceptionFileName)  
                     .Replace("[ExceptionNetworkPath]", jlp.ExceptionFileNetworkPath)  
                     .Replace("[TrackingReferenceCode]", jlp.TrackingReferenceCode);  
             emailBody = strHTML;  
           catch (Exception ex)  
             System.Diagnostics.EventLog.WriteEntry(ex.Source, ex.Message, System.Diagnostics.EventLogEntryType.Error);  
           return emailBody;  

  • After that, you can set the updated html text from above as Body of the MailMessage and can send the email using SMTP client. Make sure you have the IsBodyHtml property of the MailMessage object set to true.

 MailAddress to = new MailAddress("email@domain");      
 MailAddress from = new MailAddress("email@domain");  
 MailMessage mail = new MailMessage(from, to);      
 mail.Subject = "Test email";  
 mail.IsBodyHtml = true;  
 mail.Body = GenerateEmailBody(jlp);  
SmtpClient smtp = new SmtpClient();  
smtp.Host = "your host address";  
smtp.Port = "port";  

Cheers! Your user will be very happy.

By taking a dynamic content block in your email copy, your subscribers get the matching email but the copy can have separate images, product offers, and even the call-to-actions can be reformed based on their customer personas.

Persian Music - Homayoon - Nemitonam English lyrics

I love this song. I have requested one of my Persian friend to translate it for me and she did really nice job.. I am sure you will love it.. " "The person who was the only person I had, was the only refuge of my lonely heart, Left me alone and went from my side I am restless form the pain of her separation … I thought she stays with me sings love song for me I thought she understand my words I didn’t know she’s unkind … Though gone, but still I am full of her love Her thought is always with me Wherever I go, she is in front of my eyes, in front of my eyes I want to stand out find a way to reduce my pain of her separation But it is not possible, There is no way I cannot bear I cannot bear The person who was the only person I had, was the only refuge of my lonely heart, Left me alone and went from my side I am restless form the pain of her separation … I thought she stays with me sings love song for me I thought she understand my words I didn’t know she’s u

Code Review - Best Practices

Code review is a great learning and knowledge sharing tool not only for the new members of the team but for the long time company veterans as well. Having a code review process in place dramatically improves the code quality and helps detect bugs in an early stage. Much of what I wanted to write here has already been captured in this great post form smartbear. However, here are the important bits:   Author: Size matters. Keep it under 400 lines. For bigger change, break down the review in meaningful chunks. Add TODO comments for future CR. Keep you changes under feature flag or in a separate feature branch to facilitate smaller incremental changes which are not ready to be released in production. Provide a detailed context of the change. I prefer documenting context in commit message and will recommend to follow similar format from Linux project [ link ] Provide details of tests performed to verify the current change. Unit tests, integration tests, verific
