Short, practical summary for a contact-us form that reliably sends mail. Common reasons a working form fails are: SMTP settings missing or wrong, hosting providers blocking outbound SMTP, using an outdated mail API, or sending from an address that fails SPF/DMARC checks. ’s class is a useful starting point, but it uses the older System.Web.Mail namespace and contains a likely typo in Send() that references _smtp instead of the SMTP field shown earlier; that will prevent the SMTP server from being set. For classic ASP.NET on the .NET Framework prefer System.Net.Mail; for newer ASP.NET Core apps prefer a library such as MailKit.

A minimal, modern approach (System.Net.Mail) looks like this:

using System.Net;
using System.Net.Mail;

var msg = new MailMessage();
msg.From = new MailAddress("no-reply@yourdomain.com", "Website");
msg.To.Add("owner@yourdomain.com");
msg.ReplyToList.Add(new MailAddress("visitor@example.com"));
msg.Subject = "Contact form subject";
msg.Body = "Message body here";

using (var smtp = new SmtpClient("smtp.yourhost.com", 587))
{
    smtp.Credentials = new NetworkCredential("smtpuser", "smtppass");
    smtp.EnableSsl = true;
    smtp.Send(msg); // or SendMailAsync in async code
}

Practical troubleshooting checklist (apply in order): confirm the SMTP host, port and credentials; enable SSL/TLS if required; verify the From address belongs to the sending domain and place the visitor’s address in ReplyTo; catch and log SmtpException (StatusCode and InnerException often show the provider response); test connectivity from the server (telnet or a simple console app) to the SMTP port; check hosting docs for blocked ports or required relay settings; and inspect mail server / spam filter bounce messages for SPF/DKIM/DMARC failures. Tutorials referenced earlier by and can help with step-by-step configuration, but the key is to capture the exact exception and SMTP response string — that is the most useful data to diagnose a failed send.

I've always used this class.. always worked like a charm.. and very easy to implement:

using System;
    using System.Web.Mail;
    using System.Collections;

    namespace Service.Classes
    {
        /// <summary>
        /// Summary description for Email.
        /// </summary>
        public class Email : IDisposable
        {

            #region –DECLARATIONS–

                private string strSMTP = string.Empty;
                private string strFrom = string.Empty;

                MailMessage mail;

            #endregion

            #region –PROPERTIES–

                public string SMTP
                {
                    get
                    {
                        return strSMTP;
                    }
                    set
                    {
                        strSMTP = value;
                    }
                }    

                public string From
                {
                    get
                    {
                        return strFrom;
                    }
                    set
                    {
