How to do it...

Navigate to the RegisterUser function and make the following changes.
Add a new string variable that accepts new input parameter named email from the request object:

         string firstname= inputJson.firstname;
         string lastname=inputJson.lastname;
         string profilePicUrl = inputJson.ProfilePicUrl;
         string email = inputJson.email;

         UserProfile objUserProfile = new  
          UserProfile(firstname,lastname,profilePicUrl,email);

Add the following code immediately after instantiating the message object:

        message = new Mail();
        message.Subject = "New User got registered 
         successfully.";
        message.From = new Email("donotreply@example.com");
        message.AddContent(new Content("text/html","Thank you so much 
         for getting registered to our site."));

        Personalization personalization = new Personalization();
        personalization.AddTo(new Email(email));
        message.AddPersonalization(personalization); 
        ....
        ....
        ....
  

        public class UserProfile : TableEntity
        {
            public UserProfile(string lastName, string firstName,string 
             profilePicUrl,string email)
            {
               ....
               ....
               this.ProfilePicUrl = profilePicUrl;
               this.Email = email;
            }
              ....
              ....
            public string ProfilePicUrl {get; set;}
            public string Email  { get; set; }
        }

Instead of hardcoding, we are passing the values of the Subject, body (content), and From address dynamically via code. It's also possible to change the values and personalize based on the needs. Note that the email will be sent to the end user who got registered by providing an email address.

Let's run a test by adding a new input field email to the test request payload, shown as follows:

        {
            "firstname": "Praveen",
            "lastname": "Sreeram", 
            "email":"example@gmail.com", 
            "ProfilePicUrl":"A Valid url here"
        }

This is the screenshot of the email that I have received:
