In this article I will explain with an example, how to send Email using
Web API and
jQuery AJAX in ASP.Net MVC Razor.
When the
Send Button is clicked, the
SendEmail Action method of the
Web API is called using
jQuery AJAX and the Email is sent.
Mail Server Settings in Web.Config file
The following Mail Server settings need to be saved in the
Web.Config file.
Note: It is necessary to use the sender’s email address credentials while defining the
Gmail SMTP Server Credentials as
Gmail the sender’s email address must be same as the
Gmail Username specified in credentials.
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="sender@gmail.com">
<network
host="smtp.gmail.com"
port="587"
enableSsl="true"
userName="sender@gmail.com"
password="GMAILor2STEP-PASSWORD"
defaultCredentials="true"/>
</smtp>
</mailSettings>
</system.net>
MailMessage class properties
Following are the required properties of the MailMessage class.
From – Sender’s email address.
To – Recipient(s) Email Address.
CC – Carbon Copies (if any).
BCC – Blind Carbon Copies (if any).
Subject – Subject of the Email.

UseDefaultCredentials – Set to True in order to allow authentication based on the Credentials of the Account used to send emails.
Credentials – Valid login credentials for the SMTP server (Gmail: email address and password).
Port – Port Number of the SMTP server (Gmail: 587).
Model
The Model class consists of following properties.
public class EmailModel
{
public string Email { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
}
Controller
The Controller consists of the following Action method.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
}
Namespaces
You will need to import the following namespaces.
using System.Net;
using System.Net.Mail;
using System.Configuration;
using System.Net.Configuration;
Web API Controller
The
Web API Controller consists of following Action method.
Action method for Sending Email
This Action method handles the
POST call made from the
JavaScript XmlHttpRequest (XHR) function.
Inside this Action method, the
Sender email address (from) is fetched from the
SmtpSection of the
Web.Config file and the values of
Subject and
Body are fetched from their respective properties of
EmailModel class object.
Setting Body of Email
The IsBodyHtml property of MailMessage class is set to TRUE.
Then, object of the
SmtpClient class is created and the settings of the Mail Server such as
Host,
Port,
EnableSsl,
Username and
Password are fetched from the
mailSettings section of the
Web.Config file and are set in respective properties of the
SmtpClient class object.
Finally, an email is sent using
Send method of the
SmtpClient class and a
Success Message displayed using
JavaScript Alert Message Box.
public class AjaxAPIController : ApiController
{
[Route("api/AjaxAPI/SendEmail")]
[HttpPost]
public string SendEmail(EmailModel email)
{
//Read SMTP section from Web.Config.
SmtpSection smtpSection = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
using (MailMessage mm = new MailMessage(smtpSection.From, email.Email))
{
mm.Subject = email.Subject;
mm.Body = email.Body;
mm.IsBodyHtml = true;
using (SmtpClient smtp = new SmtpClient())
{
smtp.Host = smtpSection.Network.Host;
smtp.EnableSsl = smtpSection.Network.EnableSsl;
NetworkCredential networkCred = new NetworkCredential(smtpSection.Network.UserName, smtpSection.Network.Password);
smtp.UseDefaultCredentials = true;
smtp.Credentials = networkCred;
smtp.Port = smtpSection.Network.Port;
smtp.Send(mm);
}
}
return "Email sent successfully.";
}
}
View
HTML Markup
The View consists of two TextBoxes, a TextArea and a Button.
The Button has been assigned with a
jQuery click event handler.
Submitting the Form
When the
Send button is clicked, the TextBoxes and TextArea values are passed to the
SendEmail Action method of
Web API using
jQuery AJAX function.
Finally, the received
Success Message is displayed using
JavaScript Alert Message Box.
