Crazy Coding: Send Email in ASP.NET MVC

In order to send emails using the SMTP server in ASP.NET MVC application, you can use the "WebMail" helper class with a method called "Send" using the namespace "using System.Web.Helpers". For details, please follow the steps below.

First of all, we have to create a new Asp.Net Application; let us see the description of how to create it.

Open Visual Studio
File>New>Project
Visual C#>Web>ASP.NET Web Application(.NET Framework)>Enter the Project Name and Browse the file path and click OK, then select MVC click OK.
Open the "Web.config" file and add the following code for SMTP settings.

Note:

Set username is your Gmail(email) and password is your email password.
You can use any SMTP server to send emails using respective port number(Here I am using Gmail).

Create a "RegisterModel.cs" class in the Model folder and add the following code.

using System.ComponentModel.DataAnnotations;

namespace EmailNotification.Models
{
    public class RegisterModel
    {
        [Required]
        public string Name { get; set; }

        [Required]
        public string Email { get; set; }

        [Required]
        public string Subject { get; set; }

        [Required]
        public string Message { get; set; }
    }
}

Go to Views > Home Open an "Index.cshtml" file and add the following code.

@model EmailNotification.Models.RegisterModel

@{
    ViewBag.Title = "Home Page";
}


@if (TempData["Success"] != null)
{
    
@TempData["Success"]
    
}

@if (TempData["Error"] != null)
{
    
@TempData["Error"]
    
}

@using (Html.BeginForm("SendEmail", "Home", FormMethod.Post))
{
    @Html.AntiForgeryToken()

@Html.ValidationSummary(true, "", new { @class = "text-danger" })
        


@Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
            


@Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
            


@Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
            


@Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control", @type = "email" } })
                @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
            


@Html.LabelFor(model => model.Subject, htmlAttributes: new { @class = "control-label col-md-2" })
            


@Html.EditorFor(model => model.Subject, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Subject, "", new { @class = "text-danger" })
            


@Html.LabelFor(model => model.Message, htmlAttributes: new { @class = "control-label col-md-2" })
            


@Html.TextAreaFor(model => model.Message, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Message, "", new { @class = "text-danger" })
            




            


}

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

Go to the Controller folder and open "HomeController.cs" file and add the following code.

using EmailNotification.Models;
using System.Web.Helpers;
using System.Web.Mvc;

namespace EmailNotification.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult SendEmail(RegisterModel model)
        {
            if (ModelState.IsValid)
            {
                string body = "Hi " + model.Name + "

";
                body += "" + model.Message + "
";
                WebMail.Send(model.Email, model.Subject, body, null, null, null, true, null, null, null, null, null, null);
                TempData["Success"] = "Email sent successfully.";
                return RedirectToAction("Index");
            }
            TempData["Error"] = "Error occured while sending Email.";
            return RedirectToAction("Index");
        }

    }
}
