 <p>As far as I know, there is no such .net class as <code>EmailService</code> Typically you use the <code>SmtpClient</code> class to send emails:</p> <pre><code>SmtpClient client = new SmtpClient("server.address.com"); MailAddress from = new MailAddress(fromAddress, fromName); MailMessage msg = new MailMessage(); msg.From = from; foreach(string addr in to) msg.To.Add(addr); msg.Body = content; msg.Subject = subject; client.Send(msg); </code></pre>
