Requesting Email Read Receipts using C# Code

In today’s digital age, communication via email has become an integral part of our personal and professional lives. Often, when sending important emails, we want to ensure that the recipient has read and acknowledged our message. This is where email read receipts come into play. In this step-by-step tutorial, we will guide you through the process of requesting email read receipts using C# with Aspose.Email for .NET.

Introduction to Email Read Receipts

Email read receipts, also known as email tracking or return receipts, allow you to receive notifications when the recipient opens and reads your email. It’s a valuable feature, especially in business communications, as it provides confirmation of message delivery and engagement.

Prerequisites

Before we dive into the code, make sure you have the following prerequisites in place:

  • Visual Studio installed on your system.
  • Aspose.Email for .NET library downloaded and referenced in your project.

Step 1: Creating a MailMessage Instance

The first step in implementing email read receipts is to create an instance of the MailMessage class. This class represents an email message and allows you to set various properties of the email.

MailMessage message = new MailMessage();

Step 2: Specifying Message Details

Now, let’s specify the details of the email message, including the sender, recipient, HTML body, and delivery notification options.

message.From = "sender@sender.com";
message.To.Add("receiver@receiver.com");
message.HtmlBody = "<html><body>This is the Html body</body></html>";
message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;
message.Headers.Add("Return-Receipt-To", "sender@sender.com");
message.Headers.Add("Disposition-Notification-To", "sender@sender.com");

Step 3: Creating an SmtpClient Instance

To send the email, we need to create an instance of the SmtpClient class, which is responsible for sending the message.

SmtpClient client = new SmtpClient();

Step 4: Configuring SMTP Settings

Configure your SMTP server settings by specifying the host server, username, password, and port number.

client.Host = "smtp.server.com";
client.Username = "Username";
client.Password = "Password";
client.Port = 25;

Step 5: Sending the Email

Finally, use the client.Send method to send the email message. If the message is sent successfully, a “Message Sent” notification will be displayed.

try
{
    client.Send(message);
    Console.WriteLine("Message sent");
}
catch (Exception ex)
{
    System.Diagnostics.Trace.WriteLine(ex.ToString());
}

With these five simple steps, you can request email read receipts when sending emails using C# and Aspose.Email for .NET. This feature adds a layer of assurance to your email communications, ensuring that you know when your important messages are read.

SmtpClient client = new SmtpClient();

// Specify your mailing host server, Username, Password and Port No
client.Host = "smtp.server.com";
client.Username = "Username";
client.Password = "Password";
client.Port = 25;

try
{
	// Client.Send will send this message
	client.Send(message);
	// Display ‘Message Sent’, only if message sent successfully
