Sometimes we may want to test email functionality without sending email to actual user. Email will be saved locally so that we can verify it sending out emails in real scenario.
In below code, SmtpClient settings are configured in App.Config. We don't need to retrieve and assign these values to SmtpClient object. These configurations should be picked up automatically by SmtpClient from App.Config. It helps to keep our code clean.

There are two parts of Code:
- Code to Send Email
- App.Config Configuration to be used to test this code.
Code to Send Email
We need to define "PickupDirectoryLocation", which will be the path where email will be saved. This should be absolute path for the disk else it will throw exception. It can also be a shared path if you want to save emails on Shared network drive.
using System;
using System.Net.Mail;
namespace SendEmailUsingC_Sharp
{
class Program
{
static void Main(string[] args)
{
var smtpClient = new SmtpClient();
var mailMessage = new MailMessage();
try
{
mailMessage.To.Add("receiversEmail@gmail.com");
mailMessage.From = new MailAddress("abc@xyz.com", "Test User");
mailMessage.Subject = "Test Email using C-Sharp";
mailMessage.Body = @"<h1>Test Email</h1>
<br/>
This is
Test Email.";
mailMessage.IsBodyHtml = true;
try
{
smtpClient.Send(mailMessage);
Console.WriteLine("Email sent successfully.");
}
catch (SmtpException smtpSpecificException)
{
Console.WriteLine(smtpSpecificException.Message);
}
}
catch (Exception ex) //General Exception
{
Console.WriteLine(ex.Message);
}
Console.ReadLine(); // This is just to pause Console Screen.
}
}
}
App.Config Configuration
<?xml version="1.0" encoding="utf-8" ?>
