Hey Guys, In this Article, we’re going to Create a very simple Email Sending Contact Form Application using C# with Asp.net Core. We’ll use a beautiful HTML5 Contact Form Template by colorlib for this Tutorial.

Email Sending Contact Form

Setting Up Project

Let’s start by creating a new Asp.net Core Project. I’m going to create an Empty Project using Dotnet CLI.

Run this Command to create a new Empty Project.

dotnet new Web

Update your “Startup.cs” to ready your Project.

public class Startup
    public void ConfigureServices(IServiceCollection services)
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        if (env.IsDevelopment())
        app.UseMvc(routes =>
                name: "default",
                template: "{controller=MailSender}/{action=Index}/{id?}");

Create 3 Folders as “Controllers”, “Views” & “wwwroot” at the root directory of your project.

Creating Controller

Inside your “Controllers” Folder Create a new File as “MailSenderController.cs” & Add this Code.

using System.Net;
using System.Net.Mail;
using FluentEmail.Core;
using Microsoft.AspNetCore.Mvc;

public class MailSenderController : Controller
    public ActionResult Index()
        return View();

    public string SendEmail(string Name, string Email, string Message){
            // Credentials
            var credentials = new NetworkCredential("[email protected]", "your-password");

            // Mail message
            var mail = new MailMessage()
                From = new MailAddress("[email protected]"),
                Subject = "Email Sender App",
                Body = Message

            mail.IsBodyHtml = true;
            mail.To.Add(new MailAddress(Email));

            // Smtp client
            var client = new SmtpClient()
                Port = 587,
                DeliveryMethod = SmtpDeliveryMethod.Network,
                UseDefaultCredentials = false,
                Host = "smtp.gmail.com",
                EnableSsl = true,
                Credentials = credentials


            return "Email Sent Successfully!";
        catch (System.Exception e)
            return e.Message;

Don’t Forget to Update your Email & Password Credentials in this Line of Code in the above Code.

var credentials = new NetworkCredential("[email protected]", "your-password");

Setting Up Contact Form Template

Now, we need to Create a Contact Form for Sending Emails.

I’m going to use this beautiful Email Sending Template by colorlib.

So, go to this Link & download the Source Code of Contact Page.

Extract the downloaded file & you’ll get this

contact form 2

Now, copy all the folders from the above image & paste inside the “wwwroot” directory in your project which we have created earlier.

Creating View

Create a new Folder inside the “Views” Folder as “MailSender” at the root directory of your Project.

Now, create a new file inside “MailSender” Folder as “Index.cshtml” & Add this Code.

<!DOCTYPE html>
<html lang="en">
  <title>Contact V2</title>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/png" href="images/icons/favicon.ico"/>

  <link rel="stylesheet" type="text/css" href="css/util.css">
  <link rel="stylesheet" type="text/css" href="css/main.css">

  <div class="bg-contact2" style="background-image: url('images/bg-01.jpg');">
    <div class="container-contact2">
      <div class="wrap-contact2">
        <span class="contact2-form-title">
          Contact Us

        <div class="wrap-input2 validate-input" data-validate="Name is required">
          <input class="input2" type="text" id="name">
          <span class="focus-input2" data-placeholder="NAME"></span>

        <div class="wrap-input2 validate-input" data-validate = "Valid email is required: [email protected]">
          <input class="input2" type="text" id="email">
          <span class="focus-input2" data-placeholder="EMAIL"></span>

        <div class="wrap-input2 validate-input" data-validate = "Message is required">
          <textarea class="input2" id="message"></textarea>
          <span class="focus-input2" data-placeholder="MESSAGE"></span>

        <div class="container-contact2-form-btn">
          <div class="wrap-contact2-form-btn">
            <div class="contact2-form-bgbtn"></div>
            <button class="contact2-form-btn" onclick="SendEmail()">
              Send Your Message

  <script src="vendor/jquery/jquery-3.2.1.min.js"></script>
  <script src="vendor/bootstrap/js/popper.js"></script>
  <script src="vendor/bootstrap/js/bootstrap.min.js"></script>
  <script src="vendor/select2/select2.min.js"></script>
  <script src="js/main.js"></script>


    function SendEmail(){

        type: "POST",
        url: '@Url.Action("SendEmail", "MailSender")',
        data: {
          Name: $("#name").val(),
          Email: $("#email").val(),
          Message: $("#message").val()
        error: function (result) {
        success: function (result) {


Testing Application

Email Sending Contact Form

Fill the Form & click on “Send Your Message” Button.

You’ll Get an Email at the Given Email Address.

Complete Source Code of the Example is also available at Github.

Secure Client Problem

You might get this Exception while trying to send an Email from your Local Host.

less secure client error

In this Case, you need to Allow Access for Less Secure Apps.

Using the same Google Account you have used in your Controller to Send Email, Go to this Link https://www.google.com/settings/security/lesssecureapps

& Allow Access for Less Secure App.

Google Less Secure App Access

Now, Test your Application again, you’ll be able to receive Email from your Application.
