Try this free email delivery service:http://zender.sharptag.com First of all you need to get new API Key by registering & confirming your email in Zender In your Visual Studio project, Install the package from Nuget. This package will add a reference to Zender.Mail in your .NET application. Zender.Mail is the client library that is built to consume Zender Web API (Alternatively, you can also download and add the Zender.Mail.dll (1.0.0.0) reference manually): PM> install-package Zender.Mail The code to send a new email: ZenderMessage message = new ZenderMessage("Your zender API Key"); MailAddress from = new MailAddress("[email protected]"); MailAddress to = new MailAddress("[email protected]"); message.From = from; message.To.Add(to); message.Subject = "Welcome!"; message.Body = "Lorem ipsum dolor sit amet, consectetur adipiscing elit."; message.IsBodyHtml = true; message.SendMailAsync();

You can send email messages with HTML formatting and attachment by using Aspose.Email for .NET Library. Try it: http://www.aspose.com/.net/email-component.aspx

Also if you are using this application on your Local Server then change the port from "587" to "25".
Anubhav Chaudhary12y ago
Hey Shaik, you are getting that error because the mail Id you are using is not authenticated by the Gmail(Google) or you are not using the Gmail Id, if you are using the Yahoo Id then SMTPClient will be "smtp.mail.yahoo.com" and if you are using Hotmail account then SMTPClient will be "smtp.live.com".

Hi Sourabh,I tried your instructions and it has worked well, thank you. I was wondering though, isn’t it a security risk to have the credentials hardcoded into the source code, considering that the code can be inspected using disassemblers? Dev

Here is my error:Error 1 The type or namespace name 'Models' does not exist in the namespace 'SendMail' (are you missing an assembly reference?) \\nc\z\users\larry.oslund\documents\visual studio 2013\Projects\Emailer1\Emailer1\Controllers\SendMailController.cs 19 42 Emailer1

I am trying to code and run your example. I am using VS2013, and am getting this error:

Introduction

Sending email is a very common task in any web application for many purposes. In daily development we need to add some mail functionality to our project to send e-mail to the customer or another in our web site.

Using the code

For sending mail from ASP.NET MVC we use the "System.Net.Mail" namespace. Let's see how to do this.

Open Visual Studio
"File" -> "New" -> "Project..."
Choose Visual C#- Web then select ASP.NET MVC4 Web Application
Add a new Internet Application then click OK

Step 1

Create a new Model Class in the model folder.

The following is the code for the new Model.

MailModel.cs

public class MailModel {
public string From {
get;
set;
}
public string To {
get;
set;
}
public string Subject {
get;
set;
}
public string Body {
get;
set;
}
}

Step 2

Create a New SendMailerController in the Controller folder.

The following is the code for the design of the new Controller.

SendMailerController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;
namespace SendMail.Controllers {
public class SendMailerController: Controller {
//
// GET: /SendMailer/
public ActionResult Index() {
return View();
}
[HttpPost]
public ViewResult Index(SendMail.Models.MailModel _objModelMail) {
if (ModelState.IsValid) {
MailMessage mail = new MailMessage();
mail.To.Add(_objModelMail.To);
mail.From = new MailAddress(_objModelMail.From);
mail.Subject = _objModelMail.Subject;
string Body = _objModelMail.Body;
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("username", "password"); // Enter seders User name and password
smtp.EnableSsl = true;
smtp.Send(mail);
return View("Index", _objModelMail);
} else {
return View();
}
}
}
}

Index.cshtml

@model SendMail.Models.MailModel
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<fieldset>
<legend>
Send Email
</legend>
@using (Html.BeginForm())
{
@Html.ValidationSummary()
From:
@Html.TextBoxFor(m=>m.From)
To:
@Html.TextBoxFor(m=>m.To)
Subject:
@Html.TextBoxFor(m=>m.Subject)
Body:
@Html.TextAreaFor(m=>m.Body)
<input type ="submit" value ="Send" />
} </fieldset>

In the code above we have the following 3 fields:

To
Subject
Message

When the user clicks the "Send" button, the mail will be sent to the specified mail address that you provide in the To TextBox. So add the following code for the [HttpPost] Method for the send button click.

SendMailerController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;
namespace SendMail.Controllers {
public class SendMailerController: Controller {
//
// GET: /SendMailer/
public ActionResult Index() {
return View();
}
[HttpPost]
public ViewResult Index(SendMail.Models.MailModel _objModelMail) {
if (ModelState.IsValid) {
MailMessage mail = new MailMessage();
mail.To.Add(_objModelMail.To);
mail.From = new MailAddress(_objModelMail.From);
mail.Subject = _objModelMail.Subject;
string Body = _objModelMail.Body;
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("username", "password"); // Enter seders User name and password
smtp.EnableSsl = true;
smtp.Send(mail);
return View("Index", _objModelMail);
} else {
return View();
}
}
}
}

Understanding the Code

In the code above we have a,

ViewResult Index(SendMail.Models.MailModel _objModelMail)

user defined method. In this method, we have a parameter of our MailModel object. Now we create a MailMessage object.

MailMessage mail = new MailMessage();

MailMessage is the main class for sending mail, it is in the System.Net.Mail namespace.

The MailMessage class has properties, the important ones are:

To
From
Cc
Bcc
Subject
Body

So we add our data into specified properties.

mail.To.Add(_objModelMail.To);
mail.From = new MailAddress(_objModelMail.From);
mail.Subject = _objModelMail.Subject;
string Body = _objModelMail.Body;
mail.Body = Body;

For sending mail we need a SMTP Server, so in ASP.Net we have the SmtpClient class, we set the SMTP settings using the properties of that class.

SmtpClient smtp = new SmtpClient();

The SMTPClient class has these basic properties:

Host
Port
UseDefaultCredential
Credentials
EnableSsl
Send

smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("username", "password");
smtp.EnableSsl = true;

In the code above is,

smtp.Host = "smtp.gmail.com";

That is the SMTP Host address of Gmail, if you want to use any other SMTP host service then please add a different SMTP host protocol, for example for Hotmail it is smtp.live.com.

For example, in,

Smtp.Port=587

587 is the port for Gmail, so for any other service port you need to change the port correspondingly.

smtp.Credentials = new System.Net.NetworkCredential("username", "password");

Smtp.Credentials specifies the Network Credentials of your Gmail id so please add your username and password instead of ("username", "password");

The following is for a secure mail server, so you enable your SSL layer.

smtp.EnableSsl = true;

Smtp.Send sends the mail so please add your MailMesssage object here. Then, based on the properties, your mail will be sent.
