Send Email using WCF Service in

Hi Friends,

In this article I will tell you how to send email using WCF Service. We can send email directly from the client; however, in some cases you can't send external emails directly. In that case we need WCF service for sending email from client.
In this article, I will first explain how to create WCF service then I will try to implement email functionality using WCF Service. In this article I am using Gmail to send email., that why user must have gmail account for sending email.

1.    Create WCF Service Class Library

Create a new Project WCF Class Library Project and Name it EmailServices. 

Step 1: Create service contract as IEmailService and add OperationContract SendEmail for sending email. This method uses gmailuseraddress ,password and email to and cc subject as parameter

    public interface IEmailService
        string SendEmail(string gmailUserAddress, string gmailUserPassword, string[] emailTo,string[] ccTo, string subject, string body, bool isBodyHtml);

Step 2: Add EmailService class and Implement IEmailService. 

public class EmailService : IEmailService
        private static string SMTPSERVER = "";
        private static int PORTNO = 587;

        public string SendEmail(string gmailUserName, string gmailUserPassword, string[] emailToAddress, string[] ccemailTo, string subject, string body, bool isBodyHtml)
            if (gmailUserName == null || gmailUserName.Trim().Length == 0)
                return "User Name Empty";
            if (gmailUserPassword == null || gmailUserPassword.Trim().Length == 0)
                return "Email Password Empty";
            if (emailToAddress == null || emailToAddress.Length == 0)
                return "Email To Address Empty";

            List<string> tempFiles = new List<string>();

            SmtpClient smtpClient = new SmtpClient(SMTPSERVER, PORTNO);
            smtpClient.EnableSsl = true;
            smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = new NetworkCredential(gmailUserName, gmailUserPassword);
            using (MailMessage message = new MailMessage())
                message.From = new MailAddress(gmailUserName);
                message.Subject = subject == null ? "" : subject;
                message.Body = body == null ? "" : body;
                message.IsBodyHtml = isBodyHtml;

                foreach (string email in emailToAddress)
                if (ccemailTo != null && ccemailTo.Length > 0)
                    foreach (string emailCc in ccemailTo)
                    return "Email Send SuccessFully";
                    return "Email Send failed";


Step 3: Build your Class library.

2.    Add WCF Service Application Project

Step 1: Add reference of Classlibrary Project to that WCFServiceHost project.
Step 2: Delete IService1.Cs and codebehind file
Step3 : Right click on that SaleService.svc and select view Markup:

Step 4: Change the Service Name from that markup:
<%@ ServiceHost Language="C#" Debug="true" Service="EmailServices.EmailService" CodeBehind="EmailService.svc.cs" %>

Step 5: And build the solution and WCFServiceHost set as startup project and EmailService.svc set as startup page and run the service


3. Testing Email Service

1.       Use WCFSTORM for testing WCF Service . You can download WCFSTORM from
2.       Open WCF Strom add following endpoint http://localhost:53818/EmailService.svc?wsdl

By using this, we have successfully send email using WCF Service

Happy Programming!!
