add an embedded code for an application that handles emails

Using the sample in this page, you can add: body.AppendLine("login");

 

When you do add a target, it will open in another page.

 

Best regards,

Jeff

mailMessage.IsBodyHtml = true; 

var body = new StringBuilder();

body.AppendFormat("Hello, {0}\n", name);

body.AppendLine(@"Your KAUH Account about to activate click

the link below to complete the actination process");

body.AppendLine("login");

mailMessage.Body = body.ToString();

Here you can see anchor tag in body.
Same way you have add
